+# Age Verification Wants Your Face, and Your Privacy

+
+Age verification laws and propositions forcing platforms to restrict content accessed by children and teens have been multiplying in recent years. The problem is, implementing such measures necessarily requires identifying each user accessing this content, one way or another. This is bad news for your privacy.<!-- more -->
+
+For a few years now, several legislators in North America, Europe, and Australia have expressed concern about children and teens accessing certain types of content online. While there is no doubt some online content can be worrisome, implementing a technological solution for this is [extremely problematic](https://www.jonaharagon.com/posts/age-verification-is-incompatible-with-the-internet/).
+
+By mandating platforms to be legally responsible to verify a user's age, regulators effectively force them to identify each user requesting access to content deemed inappropriate under a certain age threshold.
+
+If these regulations continue to proliferate, this could lead to the end of pseudonymity online.
+
+## How can age be verified online
+
+Verifying age online is [difficult](https://www.woodhullfoundation.org/fact-checked/online-age-verification-is-not-the-same-as-flashing-your-id-at-a-liquor-store/). There isn't any magical solution to it, it's either recording how a user looks or scanning official documents.
+
+Conducting verification "on-device" offers only few additional protections considering this information still has to be checked and reported with an external service, somehow.
+
+Moreover, processes used to keep this data "on-device" are often opaque. Taking into account how valuable this information is, it becomes very difficult to trust any for-profit third-party services which such a sensitive task.
+
+Users' faces and official documents are two types of very sensitive information. Who becomes responsible to collect, process, store, and safeguard this data? With whom does this data get shared, and for which other purposes? And how accurate is this data anyway?
+
+### Facial scans
+
+Some platforms and third-party providers of the rapidly growing "[identity verification industry](https://www.businessresearchinsights.com/market-reports/digital-identity-verification-market-118180)" have started to use facial recognition and face scan systems in order to determine a user's age.
+
+The problem is, the systems are [horrible for everyone's privacy](https://www.liberties.eu/en/stories/facial-recognition-privacy-concerns/44518), extremely problematic to use due to [racist and gendered biases](https://www.aclu-mn.org/en/news/biased-technology-automated-discrimination-facial-recognition), [inaccurate](https://www.eff.org/deeplinks/2025/01/face-scans-estimate-our-age-creepy-af-and-harmful) to determine the correct age, and on top of all that, [can be cheated](https://www.theregister.com/2022/05/22/ai_in_brief/).
+
+### Official documents
+
+The second solution is to require users to provide an official piece of ID. Considering an official ID often contain a photo, full legal name, date of birth, home address, and government specific codes, this is even worse.
+
+All this sensitive data then gets collected by either the platform itself or a third-party provider with little oversight or incentive to protect this data at all. Leaks and breaches for this enormous data trove are just around the corner. Unfortunately, this isn't speculative, [data leaks have already occurred](https://www.404media.co/id-verification-service-for-tiktok-uber-x-exposed-driver-licenses-au10tix/).
+
+The more copies of your official documents exist online, the greater the risk this data *will get exposed*, and the less value this document has to actually identify you when it's *truly* needed.
+
+And again, this sort of verification is easy to cheat. Any determined teenager will soon learn how to either create a fake ID, use someone else's ID, or go around this verification system in another way.
+
+Age verification laws will *without a doubt* support a flourishing criminal industry to provide fake or stolen IDs even more easily online.
+
+## Where age verification is (or will be) required
+
+In April this year, [Discord started to test age verification systems](https://www.theverge.com/news/650493/discord-age-verification-face-id-scan-experiment) using facial or ID scans, as a way to comply with [Australia](https://www.bbc.co.uk/news/articles/c89vjj0lxx9o)'s and [UK](https://www.theverge.com/2023/10/26/23922397/uk-online-safety-bill-law-passed-royal-assent-moderation-regulation)'s new laws.
+
+This measure only applies to access certain protected posts for users located in Australia and the United Kingdom and at this time, but don't be surprised if it soon gets implemented at the account level for users everywhere.
+
+In the [United States](https://action.freespeechcoalition.com/age-verification-resources/state-avs-laws/), many states have already passed some types of age verification laws, and several others have proposed such laws. In [Canada](https://www.eff.org/deeplinks/2024/09/canadas-leaders-must-reject-overbroad-age-verification-bill) and [Europe](https://digital-strategy.ec.europa.eu/en/funding/call-tenders-development-consultancy-and-support-age-verification-solution), legislators have also been pushing for similar regulations to block content online subject to age verification.
+
+There is no doubt the more countries pass similar prohibitive laws, the more other countries will soon follow.
+
+Some hope however, this month a US federal judge ruled an age verification [law in Arkansas unconstitutional](https://thehill.com/homenews/state-watch/5228836-judge-blocks-social-media-age-verification-law-in-arkansas/).
+
+## Who decides what is sensitive content
+
+When talking about age verification, most assume this only applies to obvious pornographic content. However, many of these laws have [much wider reach](https://www.eff.org/deeplinks/2025/01/impact-age-verification-measures-goes-beyond-porn-sites).
+
+For example, the Australian law prohibits access to social media altogether for anyone under the age of 16. This means that, once the law comes into full effect after its transitional period, anyone who uses social media in Australia will have to prove they are older than this age. It is likely that all Australian users will have to provide some form of identifying data to continue using their social media accounts. **This is a privacy nightmare.**
+
+When laws target specific content, definition of what is appropriate and what isn't is often too broad. Moreover, this definition is subject to change from one administration to another.
+
+There are also wide differences from one country to another. For example, some countries sadly consider simple discussions of gender identity or sexual orientation to be sensitive content. What is deemed inappropriate to children in one culture might not be the same in another.
+
+Automating this sort of censorship leads to a lot of misfiring. There has already been numerous instances of [breastfeeding photos mislabelled](https://www.cbc.ca/news/world/facebook-clarifies-breastfeeding-pics-ok-updates-rules-1.2997124) for nudity. Important educational material for sex education could get censored and inaccessible to children, who critically need access to it *before* adulthood.
+
+Who will decide which content should be censored and which shouldn't? Will countries hosting the big tech platforms end up having a greater decision power in the matter? Will platforms simply decide to apply the strongest level of restriction worldwide?
+
+## Age verification isn't effective
+
+Even if we could somehow find a global consensus that is perfectly ethical and never misfires on which content children shouldn't access, it will likely fail.
+
+Children, and teenagers especially, are and have always been incredibly effective at going around such limitation to feed their curious minds.
+
+First, there are technical tools such as VPNs and proxies of all sort to go around location-based restrictions. Then, there's the classic fake ID, and its modern evolution: deepfake face. There will also be without a doubt a growing market of pre-verified "adult" accounts up for sale online.
+
+Perhaps age verification measures will work for a couple of months, until products to evade it get the word out, then they'll become useless. Only leaving the ashes of your social media legal consenting adult pseudonymity in its path.
+
+## Why it's bad news for everyone's privacy
+
+Age verification will require all platforms and/or third-party identification service providers to collect an enormous trove of sensitive data on everyone.
+
+This goes against all principles of data minimization, generally a vital part of data protection regulations.
+
+Daily occurrences of data breach incidents have taught us we cannot trust these services to safeguard our data. Data breaches for this sensitive information are only a matter of time.
+
+The concentration of such valuable data will likely be monetized and resold either by the platforms themselves, by the for-profit third-party "age assurance" providers they use, or eventually by the criminals who stole it from them.
+
+This data trove will include face scans of children with their location (trying to pass as adults), and faces and official documents from every adult in the world using social media, if this kind of regulation gets implemented at large.
+
+**The privacy and safety implications of this are absolutely disastrous**.
+
+## Age verification is not the solution
+
+Sadly, age verification legislation will not help safeguard children from harmful content online, but it will effectively remove protection for anyone needing pseudonymity online to [stay safe](privacy-means-safety.md). Moreover, it will put everyone at a much greater risk of victimization by identify theft, impersonation, stalking, and worse.
+
+Despite the perhaps well-intended legislators, technological solutions aren't always adequate to solve every problem we have. Here again, education and content moderation are likely much better ways to deal with this sort of issues.
+
+In the meantime, don't be surprised if you cross a teenager on the street suddenly pointing their phone to scan *your* adult face, or a young relative looking in your wallet. They probably won't be looking for your money, but most likely for your adult ID.

+
+Contrary to what some policymakers seem to believe, whether naively or maliciously, encryption is not a crime. Anyone asserting encryption is a tool for crime is either painfully misinformed or is attempting to manipulate legislators to gain oppressive power over the people.<!-- more -->
+
+Encryption is not a crime, encryption is a shield.
+
+Encryption is the digital tool that protects us against all sorts of attacks. It is the lock on your digital door preventing harmful intruders from entering your home. Encryption is also the door itself, protecting your privacy and intimacy from creepy eavesdroppers while you go about your life.
+
+It's not a crime to lock your home's door for protection, **why would it be a crime to lock your digital door?**
+
+[Encryption protects you](privacy-means-safety.md) from cyberattack, identity theft, discrimination, doxxing, stalking, sexual violence, physical harm, and much more.
+
+## Who says encryption is a crime
+
+Anyone who is well-informed will find it hard to believe someone could want to sabotage such fantastic protection.
+
+Yet, [year](https://www.wired.com/1993/02/crypto-rebels/) after [year](https://www.wired.com/story/a-new-era-of-attacks-on-encryption-is-starting-to-heat-up/), oppressive regimes and lazy or greedy [law enforcement](https://www.techradar.com/computing/cyber-security/anonymity-is-not-a-fundamental-right-experts-disagree-with-europol-chiefs-request-for-encryption-back-door) entities around the world have attempted to [undermine encryption](https://www.howtogeek.com/544727/what-is-an-encryption-backdoor/) using the pretext this is needed to "solve crime", despite all the experts *repeatedly* warning on how [unnecessary](https://arstechnica.com/tech-policy/2019/08/post-snowden-tech-became-more-secure-but-is-govt-really-at-risk-of-going-dark/) and [dangerous](https://www.globalencryption.org/2020/11/breaking-encryption-myths/) this would be. And this is without accounting for all the countries where encryption is *already* [severely restricted](https://www.gp-digital.org/world-map-of-encryption/), such as Russia, China, India, Iran, Egypt, Cuba, and others.
+
+Whether breaking encryption is brought up naively by misinformed authorities, or as a disguised excuse for mass surveillance is up for debate.
+
+Nevertheless, the result is the same: An attempt to destroy **a tool we all need to stay safe**.
+
+## Encryption is a protective shield
+
+Encryption, moreover end-to-end encryption, is a tool we all use in our digital life to stay safe.
+
+In today's world, the boundary between online and offline life is largely dissolved. Almost everything we do "offline" has a record of it "online". Online life is regular life now. It's not just your browsing history.
+
+Your medical record from a visit at the clinic, your purchase transaction from a trip to the store, your travel photos saved in the cloud, your text conversations with your friends, family, and children, are all likely protected with encryption, perhaps even with *end-to-end* encryption.
+
+Such a large trove of personal data needs to be protected against eavesdropping and malicious attacks for everyone to stay safe.
+
+Encryption offers this protection. End-to-end encryption all the more.
+
+## What is end-to-end encryption, and what is the war against it
+
+End-to-end encryption is a type of encryption where only the intended recipient(s) have the ability to decrypt (read) the encrypted data.
+
+This means that if you send a message through [Signal](https://signal.org/) for example, only the participants to this conversation will be able to read the content of this conversation. Even Signal cannot know what is being discussed on Signal.
+
+This greatly annoys some over-controlling authorities who would like to be granted unlimited power to spy on anyone anytime they wish, for vaguely defined purposes that could change at any moment.
+
+End-to-end encryption can also mean a situation where you are "both ends" of the communication.
+
+For example, when enabling Apple's [Advanced Data Protection for iCloud](https://support.apple.com/en-ca/guide/security/sec973254c5f/web) (ADP), it activates end-to-end encryption protection for almost all of iCloud data, including photos. This means that even Apple could not see your photos, or be forced to share your photos with a governmental entity.
+
+Without ADP, Apple can read or share your photos (or other data) if they are legally compelled to, or if they feel like it. The same is true for Google's services, Microsoft's services, and any other online services that aren't end-to-end encrypted.
+
+This is at the root of the latest attack on encryption:
+
+In February this year, it was reported that [Apple was served with a notice](uk-forced-apple-to-remove-adp.md) from the UK's Home Office to force it to break ADP's end-to-end encryption. In response, Apple removed access to ADP from the UK entirely, making this protection unavailable to UK residents.
+
+Do not mistakenly think this attack is limited to the UK and Apple users, however. If this regulation notice or a similar one gets enforced, it would **impact the whole world.** Other countries would likely soon follow, and other services would likely soon get under attack as well.
+
+Moreover, do not feel unaffected just because you use end-to-end encryption with [Signal](https://www-svt-se.translate.goog/nyheter/inrikes/signal-lamnar-sverige-om-regeringens-forslag-pa-datalagring-klubbas?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-US&_x_tr_pto=wapp) or [Proton](https://www.techradar.com/vpn/vpn-privacy-security/secure-encryption-and-online-anonymity-are-now-at-risk-in-switzerland-heres-what-you-need-to-know) services instead of Apple, they are both **under attack** as well in this war.
+
+Just in recent years, the war against encryption has affected the [US](https://www.eff.org/deeplinks/2023/04/earn-it-bill-back-again-seeking-scan-our-messages-and-photos), the [UK](https://www.bbc.co.uk/news/articles/cgj54eq4vejo), [Sweden](https://www.globalencryption.org/2025/04/joint-letter-on-swedish-data-storage-and-access-to-electronic-information-legislation/), [France](https://www.laquadrature.net/en/warondrugslaw/), [Australia, New Zealand, Canada, India, Japan](https://www.theverge.com/2020/10/12/21513212/backdoor-encryption-access-us-canada-australia-new-zealand-uk-india-japan), and all the European Union countries with proposals such as [Chat Control](the-future-of-privacy.md/#chat-control-wants-to-break-end-to-end-encryption).
+
+## The arguments given to break encryption make no sense
+
+Authoritarian entities generally use the same populist excuses to justify their senseless demands. "Protecting the children" is always a fashionable disingenuous argument.
+
+Because no one would disagree that protecting the children is important, it is often used as an attempt to deceitfully make an irrefutable argument to justify breaking encryption.
+
+The problem is, **breaking encryption doesn't protect the children**, it [endangers](https://www.theguardian.com/technology/2022/jan/21/end-to-end-encryption-protects-children-says-uk-information-watchdog) them.
+
+When law enforcement officials claim they need to be able to read everyone's messages and see everyone's personal photos to be able to fight child predators, they seem to neglect that:
+
+- This means they will expose the children's messages, contact information, locations, and photos in the process, potentially *endangering the children further*.
+
+- Exposing everyone's data will make this data much more likely to be found and exploited by criminals, making *everyone* more vulnerable to attacks.
+
+- Predators will simply move to underground channels, [unbothered](https://www.schneier.com/blog/archives/2015/07/back_doors_wont.html).
+
+They use the same kind of deceptive argument trying to justify weakening the protections we have to supposedly catch "criminals" and "terrorists".
+
+Of course the exact definition of what is a "criminal" or a "terrorist" is always vague and subject to change. In the past, human rights activists and authoritarian regime dissidents have been labeled as such, climate change activists as well, LGBTQ+ people even in some countries. Maybe next year this label will include "DEI advocates", who knows where they draw the line and what can be considered a "criminal" worth spying on.
+
+You *cannot* remove everyone's right to privacy and protection from harm while pretending it is to protect them. No one who is well-informed and well-intended could possibly consider this a smart thing to do.
+
+**An attack on end-to-end encryption isn't an attack on criminals, it's an attack on all of us.**
+
+## Magical backdoor only for "the good guys" is a complete fantasy
+
+Let's say the strategy is akin to creating a MagicalKey that unlocks every door (a magical key because thinking encryption backdoors would only be used by "the good guys" is a great example of [magical thinking](https://www.britannica.com/science/magical-thinking)).
+
+Imagine, for the sake of this exercise, the MagicalLock for this MagicalKey is impossible to pick, and imagine only police officers have MagicalKeys. Let's say one thousand police officers each have a MagicalKey.
+
+They argue they need to be able to unlock anyone's door if they suspect a crime is happening inside. "It's for safety!"
+
+Overtime, let's say only 1% of the police officers accidentally lose their MagicalKey. This kind of things happen. Now 10 MagicalKeys are lost in the wild and could be used by anyone else, for any purposes, including crime.
+
+Then, let's say only 0.1% of police officers get corrupted by a crime gang. That's just one right? This corrupted "good guy" lets the gang create a double of the MagicalKey. Which crime gang wouldn't want a key that can magically open any door? They pay the police officer good money for this. It's an investment.
+
+Now, the gang creates doubles of the MagicalKey they have. They obfuscate its serial number, so it cannot be traced back to them. They use it subtly at first to avoid detection. They make sure they never leave traces behind, so victims have no idea their door got unlocked.
+
+During this time, they steal your data, they sell it, they use it to impersonate you, they use it to harm you and your loved ones.
+
+Then, another criminal figures out on their own how to emulate a MagicalKey without even having access to one. The criminal creates a reproducible mold for this Emulated-MagicalKey and sells it to other criminals on the criminal market. Now, the MagicalKey™️ is available to any criminals looking for it. Restrictions on the backdoor are off. **Your personal data is up for grabs.**
+
+This is what is going to happen if backdoors are implemented in end-to-end encryption. But don't worry they say, "it's only for the good guys!".
+
+At least, the criminals' data will also be up for grabs, right?
+
+Nope! The criminals knew about this, so they just started using different channels that weren't impacted. Criminals will have their privacy intact, they don't care about using illegal tools, but **your legal privacy protections will be gone**.
+
+*Backdoored* end-to-end encryption isn't end-to-end anymore, it's just open-ended encryption. This offers pretty much no protection at all.
+
+## Ignoring experts doesn't make facts disappear
+
+Where is the opposition to this? Where are the experts pushing against this nightmare? Everywhere.
+
+Thankfully, opposition has been strong, despite the relentless ignorance or malevolence from authoritarian authorities repeatedly pushing against encryption.
+
+Many people and groups have been fighting valiantly to defend our collective right to privacy and security. Countless experts have patiently taken the time to explain [again](https://signal.org/blog/uk-online-safety-bill/) and [again](https://www.globalencryption.org/2020/10/cdt-gpd-and-internet-society-reject-time-worn-argument-for-encryption-backdoors/) and [again](https://www.schneier.com/wp-content/uploads/2016/09/paper-keys-under-doormats-CSAIL.pdf) how an encryption backdoor only for "the good guys" is simply impossible.
+
+Weakening encryption to let "the good guys" enter, lets *anyone* enter, including criminals. There is no way around this.
+
+Seemingly ignoring warnings and advice from the most respected specialists in the field, authoritarian officials continue to push against encryption. So much so that it has become difficult to assume good intent misguided by ignorance at this point.
+
+Unfortunately, ignoring the experts or silencing the debate will not make the facts magically disappear.
+
+In an encouraging development this week, Apple [won a case](https://www.bbc.co.uk/news/articles/cvgn1lz3v4no) fighting an attempt from the UK Home Office to hide from the public details of their latest attack on encryption.
+
+This battle and all battles to protect our privacy rights, *must* be fought is broad daylight, for all to see and to support.
+
+## Fight for encryption rights everywhere you can
+
+The war against encryption isn't anything new, it has been happening for decades. However, the quantity of data, personal and sensitive data, that is collected, stored, and shared about us is much larger today. It is essential we use the proper tools to secure this information.
+
+This is what have changed, and what is making encryption and end-to-end encryption even more indispensable today.
+
+Mass surveillance will not keep us safe, it will endanger us further and damage our democracies and freedoms in irreparable ways.
+
+We must fight to keep our right to privacy, and use of strong end-to-end encryption to protect ourselves, our friends, our family, and yes also to protect the children.
+
+### How can you support the right to encryption?
+
+- [x] Use end-to-end encryption everywhere you can.
+
+- [x] Talk about the benefits of end-to-end encryption to everyone around you, especially your loved ones less knowledgeable about technology. Talk about how it is essential to protect everyone's data, including the children's.
+
+- [x] Use social media to promote the benefits of end-to-end encryption and post about how it protects us all.
+
+- [x] Write or call your government representatives to let them know you care about end-to-end encryption and are worried about dangerous backdoors or chat control proposals.
+
+- [x] Support organizations fighting for encryption, such as:
+
+    - [Global Encryption Coalition](https://www.globalencryption.org/)
+
+    - [Open Rights Group](https://www.openrightsgroup.org/campaign/save-encryption/)
+
+    - [Fight For The Future](https://www.makedmssafe.com/)

+
+    - [Privacy Guides](https://www.privacyguides.org/en/about/donate/) 💛
+
+Finally, have a look at our [recommendations](https://www.privacyguides.org/en/tools/) if you want to start using more tools protecting your privacy using end-to-end encryption.
+
+This is a long war, but the importance of it doesn't allow us to give up.
+
+We must continue fighting for the right to protect our data with end-to-end encryption, **we owe it to ourselves, our loved ones, and the future generations.**

+
+## :simple-torbrowser: What is Tor
+
+Tor is an overlay network that was specifically designed to protect the privacy of its users. The Tor Network uses multiple layers of encryption and relays in order to protect a person's location and other potential identifiers, such as an IP address.
+
+Its name comes from the acronym for **The Onion Router**, a [routing system](https://en.wikipedia.org/wiki/Onion_routing) using multiple layers that can get peeled off at each step, like an onion 🧅
+
+This special network can be easily accessed by anyone, for free, through the Tor Browser. The Tor Browser is as easy to use as any other browser you are familiar with already.
+
+Both the tools for the Tor Network and the Tor Browser are maintained by a nonprofit organization called the Tor Project.
+
+### The Tor Network
+
+The [Tor Network](https://en.wikipedia.org/wiki/Tor_(network)) was deployed in 2002, although its core principle was developed in the mid 1990s. It was first created at the United States Naval Research Laboratory in order to protect intelligence communication online.
+
+In 2004, the laboratory released the project's code under a free and open source license, and the Electronic Frontier Foundation (EFF) began funding its development. A few years later, the onion routing project officially became the Tor Project.
+
+Today, Tor is one of the [largest](https://metrics.torproject.org/) anonymity networks, with thousands of relays and millions of users worldwide.
+
+#### How does it work
+
+The Tor Network is run by a community of volunteers who operate the relays required for the network to function.
+
+Each time someone uses the Tor Network, the communication passes through at least 3 relays: A Guard Relay, a Middle Relay, and an Exit Relay. Each relay has a different function to protect the communication.
+
+**The Guard Relay** knows where the communication is from (IP address), but doesn't know where it's going (which website is visited, for example). This relay only knows that you want to access the Tor Network. Its task is to send your encrypted communication to a Middle Relay, but it cannot read it.
+
+**The Middle Relay** doesn't really know anything. It doesn't know who you are nor where you are going. It only knows a Guard Relay wants to send encrypted data to an Exit Relay. The Middle Relay transfers this communication from one relay to another, and it cannot read it either.
+
+**The Exit Relay** has no idea who you are. It only knows someone, somewhere, wants to access this website (or other content). The Exit Relay will get the information from the website, then send it back to the Middle Relay, so that you can receive it from the Guard Relay. If you only visit pages using HTTPS, the Exit Relay can know someone is visiting this website, but cannot know what they are doing on it. Visiting *non-onion* websites using HTTPS instead of just HTTP is **[very important](https://support.torproject.org/https/https-1/)** for security and privacy.
+
+<div class="admonition info" markdown>
+<p class="admonition-title">Onion service websites</p>
+
+Onion service websites are special websites that can only be accessed using the Tor Network.
+
+They are easy to recognize because they use the .onion domain at the end, and are often composed of a long string of seemingly random characters. Onion websites offer protections equivalent to HTTPS.
+
+You can see this represented by the [onion padlock icon](https://support.torproject.org/onionservices/onionservices-5/) in the Tor Browser.
+
+</div>
+
+#### How Tor works using a letter and envelopes analogy
+
+Tor works a bit as if you put a letter (request) into an envelope with someone's address. Then, you put this envelope in another envelope addressed to someone else, with instructions. Finally, you put this second envelope in yet another one.
+
+Each envelope protects the content of the other, and can only be opened one at the time by each recipient. In this analogy, each recipient (relay) has a key that can only open the envelope addressed to them, and not the others.
+
+![Graphic representation of a Tor Circuit composed of a Guard Relay, a Middle Relay, and an Exit Relay using a letter and envelopes analogy.](../assets/images/in-praise-of-tor/tor-diagram.webp)
+<small aria-hidden="true">Illustration: Em / Privacy Guides</small>
+
+#### What is a Tor Circuit
+
+The network of randomly selected relays to complete a request on the Tor Network is called a Tor Circuit. This circuit changes each time a new connection is established.
+
+From the Tor Browser, you can see each relay that was selected for a circuit, and even change it manually. To generate a new circuit, click on the "Tor Circuit" button on the upper-left of the browser, then on "New Tor circuit for this site" at the bottom.
+
+![Screenshot from the Tor Browser showing a popup window from the Tor Circuit button.](../assets/images/in-praise-of-tor/tor-torcircuit.webp)
+
+### The Tor Browser
+
+The [Tor Browser](https://www.torproject.org/download/) was created in 2008 to facilitate access to the Tor Network. It is a modified version of Mozilla's Firefox browser, and can be installed on Linux, macOS, Windows, and Android systems.
+
+The Tor Browser start configuration is private by default. No additional extensions are required to make it more secure or more private. Actually, it's even discouraged to install any additional extensions, as this would weaken its [fingerprinting resistance](https://blog.torproject.org/browser-fingerprinting-introduction-and-challenges-ahead/).
+
+<div class="admonition warning" markdown>
+<p class="admonition-title">Highest security settings</p>
+
+Even if the Tor Browser is configured to be private by default, if you are in an especially sensitive situation, for example if you are using Tor as a whistleblower or a dissident activist, you might want to adjust the Tor Browser security level to "Safest".
+
+For this, click on the shield icon on the upper-right, then on the "Settings" button in blue, and select "Safest" instead of the default "Standard".
+
+**Important:** Each time you change the security level, you **must** make sure to restart the browser to ensure all changes have taken effect. Otherwise, [some changes](tor-security-slider-flaw.md) might not have been applied yet.
+
+</div>
+
+![Screenshot from the Tor Browser showing a warning from the SecureDrop website to adjust Tor security level to Safest.](../assets/images/in-praise-of-tor/tor-safestsetting.webp)
+
+The default search engine is the privacy-focused [DuckDuckGo](https://www.privacyguides.org/en/search-engines/#duckduckgo). You will not even find Google in the options for the default search engine. More browsers should follow this good practice.
+
+The first page opening with the Tor Browser will give the option to Connect to Tor. From there, you can click on "Connect" to start browsing through Tor, or on "Configure Connection" if you need additional settings. For example, if you need to set up a [Bridge](https://bridges.torproject.org/) because Tor is blocked from your country.
+
+<div class="admonition warning" markdown>
+<p class="admonition-title">Only connect to Tor if it is safe for you</p>
+
+Be careful when using Tor from a country where Tor might be blocked or perceived as suspicious. Similarly, be careful if you connect from a location where revealing you have been using Tor [could](#depending-on-where-you-are-using-tor-is-likely-safe) be dangerous to you.
+
+</div>
+
+![Screenshot from the Tor Browser showing the "Connect to Tor" welcome page.](../assets/images/in-praise-of-tor/tor-torbrowser.webp)
+
+Once connected to the Tor Network, you will be directed to the DuckDuckGo welcome page, and you can search or type any URLs in the address bar, like you would with any other browser.
+
+If you know an organization has an onion site (a website that is only accessible through Tor), you can type this onion address directly in the address bar.
+
+If you don't know if an organization has an onion site, you might find it from its regular URL. For example, if you visit privacyguides.org from the Tor Browser, you will notice a purple button on the right informing you that an onion version of this website is available, click on it to get redirected to it.
+
+![Screenshot from the Tor Browser showing the Privacy Guides website with an onion available purple button right to the address bar.](../assets/images/in-praise-of-tor/tor-privacyguides.webp)
+
+<div class="admonition info" markdown>
+<p class="admonition-title">Mullvad Browser and the Tor Project</p>
+
+If you are familiar with the Mullvad Browser, know that the Mullvad Browser was developed by the Tor Project team!
+
+The Mullvad Browser was born of a [collaboration](https://blog.torproject.org/releasing-mullvad-browser/) between Mullvad VPN and the Tor Project, to build a browser that offers similar privacy features to the Tor Browser, but while using it through a VPN instead of through the Tor Network (both offering different benefits).
+
+The Mullvad Browser can also be used without a VPN, and will still provide better privacy protections than most other browsers. It cannot be used to access the Tor Network, however.
+
+</div>
+
+### The Tor Project
+
+The [Tor Project](https://www.torproject.org/) is the US-based nonprofit organization maintaining the software and community for the Tor Network, and developing and maintaining the Tor Browser. It's also a privacy advocacy organization, with a mission to advance human rights and freedoms around the world through the free technology it creates.
+
+The nonprofit was founded in 2006 and gets its funding from [various sources](https://www.torproject.org/about/supporters/) including government grants, independent contributors, and individual [donations](https://donate.torproject.org/).
+
+## :octicons-lock-16: What Tor can do
+
+### Improve Privacy
+
+Tor is not magical, but it's by far one of the best privacy tool we have. Using Tor will not make you perfectly anonymous online, but it will greatly reduce the traces your leave online.
+
+Here are a few benefits Tor can provide for your privacy:
+
+- Tor can prevent the websites you are visiting from collecting your IP address (and your IP address can indeed lead to identifying *you*).
+
+- Tor can prevent your Internet Service Provider (ISP), Virtual Private Network (VPN) provider, or authorities requesting information from them to collect a list of the websites you have visited. They will know however that you have been using Tor.
+
+- The Tor Browser isolates each website you visit. This prevents ads and trackers from following you around, potentially popping up later in your [Facebook ads and accidentally outing you](https://www.intomore.com/culture/you/facebook-ads-outed-me/).
+
+- The Tor Browser is fingerprinting resistant. This reduces the ways you can be tracked and identified online, even without your IP address.
+
+- When keeping the default settings, the Tor Browser only uses private windows and will not keep any traces of your browsing history. It will also delete all cookies and site data when closing.
+
+### Circumvent censorship
+
+Because of how the Tor Network redirects traffic, it's a perfect tool to resist censorship. Using Tor can give access to websites or services that aren't accessible from a country blocking them.
+
+Even from a region where Tor itself is actively blocked, the network can still be accessed using [pluggable transports](https://tb-manual.torproject.org/circumvention/).
+
+Using this type of measures to circumvent government censorship will make Tor accessible even from countries with heavily censored internet, such as [China](https://support.torproject.org/censorship/connecting-from-china/), [Russia](https://blog.torproject.org/call-for-webtunnel-bridges/), [Iran](https://forum.torproject.org/t/iran-circumventing-censorship-with-tor/4590), and many others.
+
+<div class="admonition question" markdown>
+<p class="admonition-title">If you can't download the Tor Browser from your country</p>
+
+If you cannot download the Tor Browser because of your country's censorship, and **if it is safe for you to do**, you can try downloading the browser from a proxy website such as the [EFF website](https://tor.eff.org/), the [Calyx Institute website](https://tor.calyxinstitute.org/).
+
+You can even directly email **<gettor@torproject.org>** and send the name of your operating system (Linux, macOS, Windows) to get a direct link to download the Tor Browser.
+
+</div>
+
+If you want to help people around the world access the internet freely, you can volunteer to run a [Tor Snowflake](https://snowflake.torproject.org/) proxy. For more tech-savvy volunteers, you can also help by running a [Tor Bridge](https://community.torproject.org/relay/setup/bridge/), or even a [WebTunnel Bridge](https://community.torproject.org/relay/setup/webtunnel/).
+
+## :octicons-heart-16: Why Tor is so important
+
+### Tor is vital for human rights and democracy
+
+Tor is an essential tool for journalists, activists, whistleblowers, dissidents, and people in vulnerable situations everywhere. It is one of the best tool we have to increase privacy online, and to resist censorship from oppressive regimes.
+
+Thanks to Tor, activists have a safe way to continue fighting for human rights.
+
+Some of the most respected human rights organizations use Tor to offer safe access to their services and information. This includes organizations such as [Amnesty International](https://www.amnesty.org/en/latest/news/2023/12/global-amnesty-international-website-launches-on-tor-network-to-help-universal-access/), [Electronic Frontier Foundation](https://www.eff.org/deeplinks/2023/04/eff-now-has-tor-onions), Freedom of The Press Foundation, and of course the Tor Project.
+
+Without Tor, journalists would lose invaluable sources of information provided by courageous whistleblowers reporting in the public interest.
+
+Without Tor, brave citizens fighting against authoritarian governments would be at much greater risk when organizing and bringing vital information to the public's attention.
+
+Without Tor, victims of domestic violence and LGBTQ+ people living in hostile environments could be in much greater danger when researching life-saving information online.
+
+Without Tor, people living in oppressive regimes would not have access to the crucial information they need to fight for freedom, democracy, and peace.
+
+<div class="admonition success" markdown>
+<p class="admonition-title">Add an onion service for your organization's website</p>
+
+If you would like to add this service for your website to help more people access it safely, you can [read more](https://blog.torproject.org/more-onions-porfavor/) about onion services on the Tor Project Blog. As of 2021, you can even [get](https://blog.torproject.org/tls-certificate-for-onion-site/) domain-validated certificates for your onion site using HARICA, an operator founded by a nonprofit civil society from Greece.
+
+</div>
+
+### Tor is for everyone to use
+
+Tor is a tool that can help so many people. But Tor isn't *only* for people in highly sensitive situations like whistleblowers and journalists, Tor is for everyone!
+
+Of course, people in more dangerous situations will *need* Tor to stay safe, but everyone can benefit from Tor's privacy protections in their daily lives. I personally use Tor when I am forced to visit Google Map. Not because it's dangerous to me, but just because I greatly dislike the idea of Google tracking my location activities.
+
+Tor can also help fighting surveillance capitalism!
+
+Moreover, you can considerably help people in dangerous situations by using Tor for trivial reasons like I do.
+
+By using Tor for banal activities, when you aren't in any danger worse than a nasty ad-attack, you help to normalize the use of Tor and add more noise to the traffic. The more people do this, the more using Tor becomes just something people do when they care about privacy online, and nothing more.
+
+### Who uses Tor?
+
+- Anyone who cares about privacy!
+- Journalists who need to conduct research and protect their sources.
+- Whistleblowers using special websites to communication information to newspapers anonymously.
+- Democracy activists fighting against authoritarian governments who require anonymity online to stay safe from persecution.
+- People living under oppressive regimes who need to circumvent their country's censorship to access information freely.
+- Victims of domestic violence who need to research safe shelters and supportive resources without raising suspicion from their aggressor.
+- LGBTQ+ people living in hostile environments who need to access information online and stay connected with their community.
+- Generous people who want to [help and support](https://blog.torproject.org/support-tor-project-share-your-story/) all the above 💜
+
+The Tor community has gathered this [wonderful collection of anonymous user stories](https://community.torproject.org/outreach/stories/) from people describing why they use Tor.
+
+### Tor is critical public infrastructure
+
+To keep Tor strong for everyone, it's essential to support and grow the network of volunteer-operated relays forming the Tor Network.
+
+Thousands of journalists and activists rely on the Tor Network every day to stay safe and to continue their important work.
+
+Furthermore, **countless privacy-oriented projects depend on the Tor Network**.
+
+To name only a few, the messaging applications [Briar](https://briarproject.org/), [Cwtch](https://docs.cwtch.im/), and [SimpleX](https://simplex.chat/) all use Tor to harden some of their privacy-preserving features.
+
+For whistleblowers to stay safe, both [SecureDrop](https://securedrop.org/) and [Hush Line](https://hushline.app/) use the Tor Network. Many [newsrooms around the world](https://securedrop.org/directory/) host onion services to protect sources, such as The Guardian in the UK, CBC in Canada, ProPublica in the US, and many more.
+
+There's also all the applications protecting people with the highest needs such as [Tails](https://tails.net/), [OnionShare](https://onionshare.org/), and [more](https://github.com/Polycarbohydrate/awesome-tor).
+
+**Losing the Tor Network would mean losing all the applications and features relying on it.**
+
+This would be disastrous for the privacy community, journalists, activists, dissidents, victims of domestic violence, LGBTQ+ population, and so many worldwide.
+
+From a human rights perspective, **we simply cannot afford to lose Tor**.
+
+## :octicons-question-16: Things to consider when using Tor
+
+### Tor compared to VPN protections
+
+When using a VPN, your ISP will not know which websites you visit online (or other activities). Your ISP will see that you are connecting to a VPN, but will not know what you do from there. Your VPN however *could* know which websites you visit. Using a VPN is a transfer of trust from your ISP. When using a VPN, you should always trust your VPN provider more than your ISP.
+
+The websites you visit will see the IP address of your VPN provider instead of yours. This can help protect your identity and location, but they will know this connection uses a VPN.
+
+VPNs can offer great benefits for your privacy. However, if your VPN provider was compelled by law to provide the logs of the websites you visited (or will visit), it is *technically* possible to do for them.
+
+When using the Tor Network correctly, no one knows which websites *you visited*, or other services you accessed. Your ISP or VPN provider will only know you have accessed Tor, but will not know which websites you have visited from there. Even if compelled by law, they could only share that you have accessed Tor, at this specific time.
+
+The websites you have visited also won't know who you are (unless you tell them). They will only know someone accessed their websites through Tor, at this specific time.
+
+The relays used for a Tor Circuit cannot alone re-recreate the link between your IP address and the websites you visit either. This offers much stronger protection for your privacy than a VPN does.
+
+### Who knows you are using Tor
+
+When using the Tor Network, your ISP and the Guard Relay will both know you (the IP address you are using) are using Tor.
+
+To prevent this, you [could](https://www.privacyguides.org/en/advanced/tor-overview/#safely-connecting-to-tor) use Tor from a [trustworthy VPN](https://www.privacyguides.org/en/vpn/).
+
+If you do so, your VPN provider will know you are using Tor, but your ISP will not. Your ISP will only see you are accessing your VPN, and the Tor Guard Relay will see your VPN's IP address instead of yours.
+
+### HTTPS for non-onion websites
+
+The Exit Relay from the Tor Circuit will see someone is accessing this website (or other service).
+
+If you were to use Tor to visit a non-onion website that isn't protected with HTTPS, and log in with your credentials, this Exit Relay *could* technically read this information. Using HTTPS with non-onion websites is *very* important when using Tor. Onion sites offer protections that are equivalent to HTTPS.
+
+### Be careful with files when using Tor
+
+While it's safe to visit secured websites through Tor, be careful when downloading files or opening documents.
+
+Depending on what kind of files it is, there are a number of problems that could arise. For example, it's a [bad idea](https://blog.torproject.org/blog/bittorrent-over-tor-isnt-good-idea) to download torrent files over Tor. Additionally, Tor will not protect you from downloading malware or exposing metadata with shared files.
+
+If you need to share files through Tor with a *trusted* contact, [OnionShare](https://www.privacyguides.org/en/file-sharing/#onionshare) is a good option.
+
+## :octicons-stop-16: Addressing misconceptions
+
+There has been misconceptions floating around about Tor. Most of them repeat similar misinformation attributed to many other privacy tools: Why using this if you have nothing to hide? But this argument is incredibly flawed and comes from a naive understanding of privacy rights and needs.
+
+Most people use privacy tools for protection, and everyone needs protection. Moreover, [privacy is a fundamental right](https://www.privacyguides.org/videos/2025/04/17/is-privacy-dead/) intrinsically connected to democracy and civil liberties.
+
+### The dark web, the deep web, and the surface web
+
+Some misconceptions have spread from confusion on what the *deep* web and the *dark* web are. Because yes, Tor is part of the dark web.
+
+While using the term "dark web" might make for great sensationalist news title, the dark web isn't anything to fear.
+
+It's not "dark" as in "dark intent" or the "dark side of the Force". It's really just dark as in "it's so dark on this road, I can't read the addresses around".
+
+This dark web needs special software, configuration, or authorization to access it. For example, **the Tor Browser is the streetlight you need to navigate on the Onion roads**.
+
+If you use Tor to visit the Privacy Guides onion site, you will be using the dark web. It's a website (or website version) that can only be accessed using a specialized tool. That's it!
+
+The dark web is part of the deep web, which is simply all the online information that isn't indexed by any standard web search engines. Aren't you happy your bank account is on the deep web?
+
+![Illustration of an iceberg where the tip above water represents the surface web, the part underwater represents the deep web, and the part under the iceberg represents the dark web.](../assets/images/in-praise-of-tor/tor-darkweb.webp)
+<small aria-hidden="true">Illustration: Em / Privacy Guides | Inspired by: [Ranjithsiji](https://commons.wikimedia.org/wiki/File:Iceberg_of_Webs.svg)</small>
+
+### Criminals use envelopes, doors, and clothing too
+
+Some fear that Tor is used by criminals. While that might be true some criminals use Tor, a lot of people who aren't criminals at all also use Tor.
+
+This kind of argument really leads nowhere. Criminals also use Google, Facebook, and Twitter (a lot actually). Criminals use envelopes to hide their ransom letters, closed doors to hide their crimes, and clothing to conceal weapons! Are we going to forbid clothing because some (all?) criminals use clothing to hide their weapons?
+
+**We shouldn't ban clothing, and we shouldn't ban Tor either.** There are other better ways to catch criminals than removing a tool millions use to stay safe online.
+
+### Tor receives government funding
+
+Yes, Tor does receive government funding, and that's a good thing. A lot of nonprofit organizations receive government funding as a stable ([usually](https://www.privacyguides.org/articles/2025/02/03/the-future-of-privacy/#the-tools-you-use-might-depend-on-government-funding)) source of income. Our governments *should* be contributing financially to the tools we all use to improve our security and privacy for free, moreover if they are using it themselves.
+
+While any organization should thrive to diversify its sources of income to reduce its dependency on large contributors, it's not always easy to do.
+
+If you feel uneasy about a privacy tool you use receiving government funding, the best thing you can do to fight this is to [donate](https://donate.torproject.org/) directly to reduce its dependence to it.
+
+### Depending on where you are, using Tor is likely safe
+
+If you are not living under an oppressive regime with heavy censorship, it's likely that using Tor is safe for you, and will not put you on "a list". Even if it was putting you on "a list", it likely is a list full of great people working to defend human rights and privacy rights online.
+
+That being said, **if you are living in a region where using Tor is dangerous**, and could put you on a list of anti-regime dissidents, you *should absolutely* be careful and take special measures to hide your usage of Tor.
+
+Additionally, **if you are in a vulnerable situation** where an aggressor has access to your device or ISP information, and could hurt you if they knew you have used Tor, you should use a Tor Bridge and only [access Tor through Tails](https://www.privacyguides.org/articles/2025/01/29/installing-and-using-tails/).
+
+### Tor is fantastic for your privacy, but is not magical
+
+Tor is a great tool to improve your privacy online and make it much harder to identify you, your location, and the content you access online. However, it will not make you magically anonymous.
+
+If you use Tor with files containing metadata about you, this metadata can still identify you.
+
+If you use Tor to log in your Facebook account, then of course Facebook still knows it's you, and now also knows you are using Tor.
+
+If you use Tor to create a new account, but use an email address, phone number, username, or profile picture you used elsewhere when not connected through Tor, then your Tor activity can get linked to your previous activity.
+
+If you use Tor to reveal information so specific that only you, or only someone at your company, or only someone in this small government department could know, then of course authorities can identify you this way.
+
+You should also consider correlation in time when using Tor. If your activity is so specific that it can be narrowed down to only a few people, and your ISP or VPN knows you have accessed Tor at this specific time (and shares this information with authorities), a correlation in time could be enough to de-anonymize you.
+
+### Misconceptions are very detrimental to Tor, and other privacy tools
+
+We need to be extremely careful when spreading information that could be inaccurate or hasn't been verified when talking about Tor (or any other privacy tools).
+
+Misinformation can create mistaken fears and stop people from using a tool they would greatly benefit from.
+
+If someone is so scared of Tor because of some rumor they heard, that they continue their activism from the surface web instead, they could needlessly put themselves at risk.
+
+Furthermore, unjustified bad reputations can severely hurt funding for tools like Tor. This leads to less resources to continue developing the browser, the network, and to advocate for privacy everywhere.
+
+We all have a responsibility to verify which information we share with others, make sure we stop misinformation at its root, and correct harmful misconceptions everywhere we hear them.
+
+## :material-hand-heart-outline: Tor needs our support
+
+**Tor is at risk, and needs our help.** Despite its strength and history, Tor isn't safe from the same attacks oppressive regimes and misinformed legislators direct at encryption and many other privacy-enhancing technologies.
+
+Moreover, due to its US government funding, Tor has already been on the destruction path of the recent hectic government cuts. Thankfully, the US Agency for Global Media finally [rescinded the grant termination](https://www.theregister.com/2025/03/25/otf_tor_lets_encrypt_funding_lawsuit/?td=rt-3a) it had announced on March 15th to the Open Technology Fund, which the Tor Project benefits from. Sadly, considering the unpredictability of the current US administration, this doesn't mean the Tor Project is safe from cuts later on.
+
+As much as the Tor Network relies on generous volunteers to run it, the nonprofit Tor Project relies on grants and donations to survive.
+
+The good news is, we can help with both!
+
+The more individuals donate to the Tor Project, the less it depends on government funding, and the more stable its donation income becomes.
+
+Similarly, the more people volunteer to run a Tor relay, the more stable and reliable the Tor Network becomes.
+
+Tor is a privacy tool so many people, organizations, and applications need to stay safe and secure. It is **our collective responsibility to contribute what we can** to keep Tor strong and thriving for all of us.

+
+If you have been looking for a password manager giving you full control over your data, KeePassium is a fantastic option. The application available for iOS and macOS keeps your password database offline by default. KeePassium still offers synchronization and backup options, but allows you to choose which storage provider to trust with your database, and change it whenever you want.<!-- more -->
+
+![KeePassium logo](../assets/images/keepassium-review/keepassium.svg){align=right itemprop="image"}
+
+[KeePassium](https://keepassium.com/) is a commercial open-source application made by KeePassium Labs, based in Luxembourg.
+
+Because it's open-source, anyone can inspect and download its [code](https://github.com/keepassium/KeePassium) if they wish. Anyone could even [build](https://github.com/keepassium/KeePassium?tab=readme-ov-file#is-it-free) the entire application by themselves, and use the advanced features completely for free.
+
+However, if you do not want to bother with code, you can use either the basic plan for free, or pay for a premium plan to access advanced features and to support the project.
+
+KeePassium is a [KeePass](https://keepass.info/)-compatible project. If you are already familiar with any software from the [KeePass ecosystem](https://github.com/lgg/awesome-keepass), you will feel right at home with KeePassium.
+
+KeePassium's strength resides in how it integrates KeePass' security and features into a well-rounded and well-designed application, that is very instinctive to use, while not compromising on flexibility and customizability.
+
+<div class="admonition abstract" markdown>
+<p class="admonition-title">The KeePassium application</p>
+
+For this review, the words "KeePassium" and "application" refer to both the KeePassium iOS and macOS applications simultaneously, unless otherwise specified. The mobile application was tested first and will be more prominent in the examples and screenshots.
+
+</div>
+
+## :material-apple: Platforms and Compatibility
+
+KeePassium is written in Apple's Swift programming language and is available for Apple devices.
+
+### Mobile
+
+- For iPhone and iPad, KeePassium works on iOS 17.0 or later.
+
+### Desktop
+
+- For Mac computers, KeePassium works on macOS 14.0 (Sonoma) or later.
+- KeePassium is compatible with both Apple Silicon and Intel hardware.
+- The desktop application is new and was [released](https://keepassium.com/blog/2024/12/keepassium-2.0/) on December 17th, 2024.
+
+### Apple Vision
+
+- For Apple Vision, KeePassium works on visionOS 1.0 or later.
+
+### Languages
+
+The KeePassium application is available in the following languages: English, Arabic, Czech, Dutch, French, German, Italian, Japanese, Korean, Polish, Portuguese, Russian, Simplified Chinese, Slovak, Spanish, Swedish, Thai, Traditional Chinese, Turkish, and Ukrainian.
+
+### Cross-compatibility
+
+One great strength of any applications derivative of KeePass is compatibility with other KeePass applications. This is due to implementing of the same `.kdbx` file format for password databases, and often sharing similar features as well.
+
+If you use KeePassium to store your passwords, you will be able to easily transfer your password database to other KeePass-compatible applications, and vice versa. This offers powerful portability for your password database.
+
+<div class="admonition info" markdown>
+<p class="admonition-title">File formats and encryption</p>
+
+KeePassium supports the KDB, KDBX3, and KDBX4 file formats, and implements AES, ChaCha20, Twofish, and Argon2 for encryption algorithms.
+
+Even if compatibility with older database formats is available, it is recommended to use the more recent and [more secure](https://keepass.info/help/kb/kdbx_4.html) KDBX4 format. This latest format will be the default when you create a new database in KeePassium.
+
+</div>
+
+This cross-compatibility is so versatile that you could, for example, use KeePassium on mobile but sync it with [KeePassXC](installing-keepassxc-and-yubikey.md) on desktop.
+
+Similarly, if you have a Mac computer but an Android phone, you could use KeePassium on desktop but KeePassDX on mobile, and so on and so forth. You can consult KeePassium's documentation for a list of all [compatible apps](https://support.keepassium.com/kb/compatible-apps/).
+
+<div class="admonition warning" markdown>
+<p class="admonition-title">Testing compatibility</p>
+
+If you plan on using KeePassium with cloud storage and synchronization between devices, make sure to test your settings well before adding all your passwords to it.
+
+</div>
+
+Depending on your usage and settings, glitches in synchronization *could* corrupt your database file. This has more chances to happen if you use a cloud storage that isn't fully supported, or a KeePass-compatible application that isn't listed in KeePassium's documentation.
+
+Ideally, if you use synchronization, create a dummy database at first to test that synchronization works properly with your specific cloud configuration and between all the devices you use.
+
+It's also advisable to enable the backup feature and even keep a backup copy of your database file in a different directory. That way, if your main synced file were to get corrupted or lost somehow, you could always rely on this secondary backup.
+
+This is important because there is no remote database management done by KeePassium. **You are fully in control of your own data, but you are also fully responsible to protect it.**
+
+## :material-wallet-bifold-outline: Pricing
+
+KeePassium can be used completely for free!
+
+That being said, if you need advanced features, you might want to [pay](https://keepassium.com/pricing/) for a [Premium](https://keepassium.com/articles/why-upgrade-to-premium/) plan (monthly or yearly), or a Pro or Business plan. Fortunately, the monthly Premium plan is very affordable, allowing users to test the Premium features one month at the time before committing to a longer subscription.
+
+Alternatively, if you do not need any advanced features but would like to support the project, you could use the free plan and [donate](https://keepassium.com/donate/) a fix amount to KeePassium.
+
+#### Rent-to-own
+
+Something interesting about KeePassium Premium's plan is that it offers a "[rent-to-own](https://support.keepassium.com/kb/license-rent-own/)" license. This means that if you pay for a KeePassium subscription for 12 months or more, you will always "own" the features you've paid for, even if you stop paying.
+
+For example, if you pay for Premium for only one year then stop, you will keep access to all the Premium features that were available while you paid for Premium, but will not have access to new features added after your stopped paying. This is an excellent model that more applications should adopt.
+
+![Screenshot from the KeePassium website's Pricing page with a description of which features are included in each plan.](../assets/images/keepassium-review/keepassium-pricing.webp)
+
+## :octicons-shield-check-16: Security and Trust
+
+Security and trust are without a doubt the most important characteristics of a good password manager.
+
+While functionality and features are also important, there is no point in having a pretty application that doesn't safeguard your passwords properly. It would defeat the whole purpose of the password manager.
+
+KeePassium does not neglect security for convenience, and has done its homework to earn its users' trust. The database format it uses, its transparency with open source, and its independent security audit, are all factors contributing to build trust in KeePassium.
+
+### Trusted database format
+
+The application is using an encrypted database file format developed by [KeePass](https://en.wikipedia.org/wiki/KeePass), an open-source project with a good reputation in the security and privacy community. KeePass' code and formats are trusted by many other KeePass-compatible projects, including KeePassXC, KeeWeb, OneKeePass, ModernKeePass, MacPass, Keepass2Android, and [more](https://github.com/lgg/awesome-keepass).
+
+Even if the KeePassium application is relatively recent with its first [launch](https://keepassium.com/blog/2019/07/introducing-keepassium-for-ios/) in 2019, the formats it uses to secure password databases had many eyes on since the initial KeePass release in 2003. The fact that so many people have inspected, used, tested, and improved the security foundation of this file format through the years contributes to KeePassium's security as well.
+
+### Open-source code
+
+KeePassium was [created](https://keepassium.com/articles/who-created-keepassium/) by [Dr. Andrei Popleteev](https://popleteev.com/), who founded KeePassium Labs, and continues as its director to develop and maintain the app with a small team of [contributors](https://github.com/keepassium/KeePassium/graphs/contributors). Like KeePass, KeePassium's code is open-source under a [GNU General Public License](https://github.com/keepassium/KeePassium/blob/master/LICENSE.txt).
+
+Open-source code isn't magical, but it helps to build trust by providing full transparency. Because all of KeePassium's code is publicly accessible, anyone could inspect it. This can help to detect and reporting potential vulnerabilities early on, and quickly verifying any claims made. Of course, at least *some* independent qualified people have to inspect the code in order to make this meaningful at all. But this is true for any open-source projects.
+
+#### A note on KeePassium's open-source commercial model
+
+More precisely, KeePassium is a *commercial* open-source application. This means its code is fully open and available to inspect, download, and use (within its license's limits). However, users can also purchase paid plans to access advanced features, without having to build and manage the code themselves.
+
+Paid plans provide a source of revenue to KeePassium, which helps to maintain the application adequately to keep it compatible and secure, providing support to customers, and adding new features down the line.
+
+This commercial model can actually add stability to a project, making it more likely to survive long term. This is reassuring considering all the other KeePass-compatible projects that have stopped getting maintained and are unfortunately no longer usable.
+
+Furthermore, there is some [conflict](https://www.engadget.com/2011-01-09-the-gpl-the-app-store-and-you.html) between certain open-source licenses and publication on Apple's App Store. Because it isn't possible to download an iOS app outside of Apple's App Store (unless you adventure in the perilous waters of [jailbreaking](https://en.wikipedia.org/wiki/IOS_jailbreaking)), KeePassium and all other iOS apps are confined to operate within the App Store's requirements.
+
+Also for this reason, the KeePassium projects cannot accept external contributions to its code, but can still [accept contributions](https://github.com/keepassium/KeePassium?tab=readme-ov-file#how-to-contribute) for bug reports, feature suggestions, and translations.
+
+### Independent security audit (iOS)
+
+Perhaps one of the most compelling argument for trusting KeePassium is the [independent security audit](https://support.keepassium.com/kb/security-audits/) the iOS application went through last year.
+
+The Berlin-based cybersecurity firm [Cure53](https://en.wikipedia.org/wiki/Cure53) conducted a full evaluation and professional pentest of the mobile application in November 2024.
+
+The review included an audit of the source code, application, network communications, and the implemented cryptography. The few vulnerabilities found were all fixed following reception of the report.
+
+It's important to note that only KeePassium for iOS was audited, and not KeePassium for macOS, which was released after the audit. However, many aspects of KeePassium for iOS that were included in the audit are likely to be similar for KeePassium for macOS.
+
+Interestingly, Cure53 has [audited](https://cure53.de/) many other well-known security and privacy-focused or open-source applications such as Proton Pass, 1Password, Bitwarden, Obsidian, Mullvad VPN, Onion Browser, Threema, Briar, SecureDrop, Mastodon, and much [more](https://github.com/cure53/Publications).
+
+### Recommended by other applications
+
+Finally, if you already trust KeePassXC for your desktop password manager, know that KeePassium is one of the apps [suggested](https://keepassxc.org/docs/) by KeePassXC to use on iOS.
+
+## :octicons-lock-16: Privacy and Encryption
+
+Data privacy and encryption are fundamental aspects of any password managers. Because pretty much all data stored in a password manager is highly sensitive data, all data should be protected by strong end-to-end encryption.
+
+### Data collection
+
+On this point, KeePassium delivers. First, a quick look at Apple's privacy label indicates that "the developer does not collect any data from this app". This is a good start, and this description is true for both the iOS and macOS applications.
+
+![Screenshot from Apple's App Store for KeePassium's App Privacy label. The label states that the "developer does not collect any data from this app".](../assets/images/keepassium-review/keepassium-applelabel.webp)
+
+Second, in its current version, KeePassium's [Privacy Policy](https://keepassium.com/privacy/app/) is excellent. This is never a guarantee of course, but the app's [security audit](#independent-security-audit-ios) shows the Privacy Policy statements are likely founded.
+
+KeePassium separates its privacy policies for the application and the website. This is an excellent practice way too rarely adopted by companies. This approach provides much more clarity for what data is collected from where, and is a positive sign that an organization understands well data privacy legal requirements.
+
+The Privacy Policy for the app is detailed and thorough, which are essential qualities to any respectable privacy policies.
+
+It starts by stating clearly that KeePassium does not send any personal data to KeePassium Labs, the company developing the app. Then, it lists all instances where data *could* be collected through the purchase or use of KeePassium, and gives clear instructions on how to opt out for each. This is the kind of privacy policy that shows an organization genuinely values and understands data privacy. I highly encourage you to have a look at it from the link above.
+
+Worth noting as well, KeePassium's Privacy Policy for its *website* states it [does not use any cookies](https://keepassium.com/privacy/website/#our-use-of-cookies-and-tracking). This is certainly refreshing to read.
+
+### Encryption
+
+Although the application is compatible with older formats, KeePassium by default will use the newer KDBX4 file format to encrypt password databases.
+
+This is important because the KDBX4 format offers [significant security improvements](https://keepass.info/help/kb/kdbx_4.html) over the previous KDBX3 format. If you import an older database in KeePassium, it is recommended to upgrade it to KDBX4 and use a different main password for the upgraded database if you keep a backup of the previous one.
+
+<div class="admonition success" markdown>
+<p class="admonition-title">Upgrade from KDB to KDBX</p>
+
+If you need to upgrade an older database file to the newest file format to benefit from better security and KeePassium's full functionality, you can follow KeePassium's [instructions](https://support.keepassium.com/kb/convert-kdb-kdbx/).
+
+</div>
+
+To secure the database, and all the content included in it, KeePassium uses AES256, ChaCha20, Twofish, HMAC, and Argon2 (for KDBX4 only). Because the [KeePass database file format](https://keepass.info/help/kb/kdbx.html) (and so KeePassium's as well) encrypts the whole database, this means that not only passwords are encrypted but also usernames, website URLs, notes, attachments, etc.
+
+<div class="admonition info" markdown>
+<p class="admonition-title">Encrypting all data, not just passwords</p>
+
+Encrypting all user data contained in a password manager entry is *extremely* important, because encrypting passwords only just isn't enough.
+
+In August 2022, the password manager [LastPass suffered a security breach](https://blog.lastpass.com/posts/notice-of-recent-security-incident) where users' password vaults (databases) were stolen from LastPass' servers.
+
+This is bad enough even with end-to-end encrypted data (because vaults with a weak main password could get cracked), but even worse than this, some important data like website URLs were *not encrypted at all*, so this information was [stolen in plain text](https://www.pwndefend.com/2022/12/24/lastpass-breach-the-danger-of-metadata/).
+
+This is the perfect example of why **encrypting all data *and* metadata** input by the user is *crucial* for data privacy and security.
+
+Additionally, the LastPass' breach is a great argument in favor of keeping one's password database *offline,* whenever possible. Something that KeePassium makes possible even by default.
+
+</div>
+
+#### Encryption algorithms used by KeePassium
+
+[AES256](https://en.wikipedia.org/wiki/Advanced_Encryption_Standard): The Advanced Encryption Standard (AES) is a trusted and commonly used block cipher symmetric-key algorithm. It was established in 2001 by NIST, the American National Institute of Standards and Technology. The number following the acronym describes the key size in bits (128, 192, or 256 bits).
+
+[Twofish](https://en.wikipedia.org/wiki/Twofish): Twofish is another block cipher symmetric-key algorithm, which KeePassium can use to secure databases, in 256-bit key size as well. Famous cryptographer Bruce Schneier was part of the team who designed Twofish.
+
+[ChaCha20](https://en.wikipedia.org/wiki/Salsa20#ChaCha_variant) (KDBX4 only): The ChaCha20 algorithm is a variant of Salsa20, both stream ciphers that encrypt and decrypt data in continuous stream instead of blocks. The number refers to the number of rounds in its structure.
+
+[HMAC](https://en.wikipedia.org/wiki/HMAC) (Key Derivative Function): Hash-based Message Authentication Code (HMAC) is a robust hash function. In KeePass-compatible apps, it is used to [verify](https://keepass.info/help/kb/kdbx.html#hbs) the integrity and authenticity of the database before decryption.
+
+[Argon2](https://en.wikipedia.org/wiki/Argon2) (Key Derivative Function, for KDBX4 only): Argon2 is a memory-hard function that offers better resistance against GPU cracking attacks compared to AES-KDF. Argon2 was the winner of the Password Hashing Competition in 2015.
+
+[AES-KDF](https://keepass.info/help/kb/kdbx_4.html#intro) (Key Derivative Function, for KDBX3 only): AES-KDF is a key derivative function based on AES. This method was previously used for the KDBX3 database format, but has since been replaced by Argon2 for KDBX4. This is partly because AES-KDF is not memory-hard, which makes it easier to crack for an attacker using modern technologies.

+
+## :octicons-apps-16: Usage and Features
+
+Once solid security and privacy protections have been confirmed, the second important part of a good password manager is how easy it is to use and the features it offers.
+
+In this regard, KeePassium excels again. Not only does KeePassium offer the features users familiar with KeePass-compatible applications will recognize, but importantly, it implements these features with a polished user interface and obvious consideration for accessibility and user experience.
+
+### Starting with KeePassium on iOS
+
+Installing the app from the App Store is a smooth process. Once installed, make sure to go in Apple's "Settings" > "KeePassium" > "Siri & Search" and disable the Siri options you are not using. Apple very annoyingly puts them all on by default for each new app installed.
+
+Additionally, you can follow KeePassium's [instructions](https://keepassium.com/privacy/app/) from its Privacy Policy to opt out of other Apple settings related to KeePassium.
+
+After installing the app, KeePassium will guide you step-by-step to set up an application PIN (you can also enable application lock with biometrics), and import or create a new database.
+
+If you are not familiar with it already, it's a good idea to read each popup from the welcome screen.
+
+<div class="grid" markdown>
+
+![Screenshot from the iOS app showing the Welcome page after installation.](../assets/images/keepassium-review/keepassium-startwelcome.webp)
+
+![Screenshot from the iOS app showing the page giving options to either create a new database, add an existing database, or connect to a server.](../assets/images/keepassium-review/keepassium-startdatabase.webp)
+
+</div>
+
+<div class="admonition tip" markdown>
+<p class="admonition-title">Secure the application properly</p>
+
+When prompted to select a Passcode to lock the application (which is different from the main password to secure your database), you will have the option to switch from the numeric keypad to a full alphanumeric keyboard. This is recommended to set up a stronger Passcode to protect the application, where your database(s) might be kept unlocked if you choose this option.
+
+</div>
+
+If you create a new database to store your passwords, make sure to choose a [strong main password](https://www.privacyguides.org/en/basics/passwords-overview/#passwords) (or "Master Key") that is *unique*, *complex*, and *long*.
+
+KeePassium will guide you to determine if your main password is sufficiently strong. However, the app cannot know if you have used this password before, so you should make sure that you haven't and this main password is unique.
+
+<div class="admonition danger" markdown>
+<p class="admonition-title">Be careful to remember your main password!</p>
+
+This is the only password that cannot be stored in your password manager, so it's important to secure it properly and also ensure you can **remember it well**.
+
+Due to the nature of end-to-end encryption, there is no way for KeePassium to recover a lost password. Not remembering your main password could mean **getting locked out of your password database permanently**.
+
+</div>
+
+After creating a new database, you will be prompted to unlock it with your new main password ("Master Key").

+
+After you have either created or imported a database, you are ready to explore KeePassium's features.
+
+### Starting with KeePassium on macOS
+
+To download KeePassium on macOS, you will need to go through Apple's App Store. Alternatively, you could also [build](https://github.com/keepassium/KeePassium) the application from the source code, but that is an entirely different process.
+
+![Screenshot from Apple's App Store on macOS showing the KeePassium page.](../assets/images/keepassium-review/keepassium-appstoremac.webp)
+
+Installing the application is a breeze, and the macOS app shares the same welcome sections and features the iOS version has, with a slightly different format.
+
+![Screenshot from the macOS app showing the Welcome page after installation.](../assets/images/keepassium-review/keepassium-startwelcomemac.webp)
+
+The application will guide you to either create or import a database, then you will recognize the same features described below for the iOS version.
+
+![Screenshot from the macOS app showing the New Database section.](../assets/images/keepassium-review/keepassium-newdatabasemac.webp)
+
+### Accessibility
+
+There are a few great accessibility features with KeePassium. First, KeePassium fully works with Apple's VoiceOver. To enable it on iPhone, you can go in the iOS "Settings" > "Accessibility" > "VoiceOver" and enable "VoiceOver".
+
+Second, from the KeePassium app you can tap on the "Settings" gear button on the lower-right to access the "Appearance" menu. From there, you will see a sliding option to adjust the entry's text size. This will change the size of the text in all entries' sections. You also have the option to change the font type from there.
+
+Additionally, when tapping on a Password in an entry section, you can quickly tap on the magnified "a" button (while the blue "Copied" overlay appears) to display the password in large font, with each character separated in an indexed table.
+
+<div class="grid" markdown>
+

+
+![Screenshot from the iOS app showing an entry's password selected with the large font option, which displays each character from a password in a separate indexed box.](../assets/images/keepassium-review/keepassium-largeindexedfont.webp)
+
+</div>
+
+### Security features
+
+In the "Access Control" category of "Settings", there are some important options to customize the app's security features:
+
+#### App Protection
+
+This section gives options to secure the application itself. It includes using the device's biometric lock instead of the app's Passcode, changing the app's Passcode, and choosing when the app gets locked.
+
+#### Data Protection
+
+This section gives options to enable or disable if the database(s)' main password(s) is remembered locally in the device's secure keychain, or if it must be re-entered each time to unlock a database. It also allows you to choose when (if remembered) the database will lock itself again, how long to keep data (including copied passwords) in the device's clipboard, and other security preferences.
+
+A fun (and useful) feature you will find there is that you can decide what happens when the device is "shaken". This can be an important security feature for people in sensitive situations.
+
+<div class="grid" markdown>
+
+![Screenshot from the iOS app showing the App Protection page from the Settings.](../assets/images/keepassium-review/keepassium-appprotection.webp)
+
+![Screenshot from the iOS app showing the Data Protection page from the Settings.](../assets/images/keepassium-review/keepassium-dataprotection.webp)
+
+</div>
+
+#### Protection against weak passwords
+
+When first creating a database, KeePassium will indicate if the main password chosen is too weak and display a warning.
+
+This is an important security feature because **a database is only as protected as the strength of its main password**. It goes without saying the main password for a database should always be *unique* (has never been used elsewhere), *complex* (uses a variety of character types), and *long* (is long enough to not be vulnerable to brute-force attacks).
+
+Passwords chosen for each entry will also display an indicator of strength under each field.
+
+#### YubiKey support (Premium)
+
+For users with Premium plans, KeePassium offers [support for YubiKey](https://www.yubico.com/works-with-yubikey/catalog/keepassium/) to add extra protection to a database using the challenge-response implementation.
+
+The same feature is available on KeePassXC on desktop. For more details on this, you can check our [tutorial for KeePassXC](installing-keepassxc-and-yubikey.md), or our tutorial on [how to set up and back up a YubiKey](yubikey-reset-and-backup.md)'s challenge-response.
+
+#### Passwords audit (Premium)
+
+KeePassium offers to audit database's passwords for potential leaks. This feature works by comparing an obfuscated version of a password with the [Have I Been Pwned](https://haveibeenpwned.com/) service. The password is never shared externally during this process. This is helpful information to get an early warning and change a compromised password before the exposed account is attacked.
+
+### Groups and Smart Groups
+
+Before starting to add entries to a new database, it's a good idea to explore the Groups and Smart Groups features. Groups are directories that can be created inside a database to separate categories of passwords.
+
+Smart Groups are simply Groups created from a search query. If you imported a database already full of passwords, you might not feel like sorting them manually. Smart Groups will help to create Groups using queries to [categorize](https://support.keepassium.com/docs/smart-groups/) entries automatically. This can be very convenient to organize larger databases.
+
+When creating a new database, KeePassium will suggest some Groups, which you can be used as provided, changed, or deleted. To add a new Group or Smart Group, tap on the 3-dot button on the upper-right from inside a database and select "New Group" or "New Smart Group".
+
+![Screenshot from the iOS app showing different groups created within a database.](../assets/images/keepassium-review/keepassium-groups.webp){width="400"}
+
+<div class="admonition info" markdown>
+<p class="admonition-title">Separate databases vs Groups</p>
+
+Using separate databases for different categories of passwords, for example one database for personal passwords, work-related passwords, and family-shared passwords is a good idea because it takes advantage of compartmentalization to add extra security and privacy.
+
+Each database will have its own main password, and if one database were to get compromised, the others might still be protected. KeePassium's free plan only allow to use *one* database at the time, however.
+
+Groups mainly serve to organize passwords and do not provide any additional security, privacy, or portability like separate databases do. For free plan users, Groups can still be a great feature to separate passwords when it isn't a security issue to encrypt them all together using a same main password.
+
+</div>
+
+### Entry options
+
+Once inside a database, users can add a new entry there or first create/enter a Group directory. To create a new entry, tap on the 3-dot menu on the upper-right, then select "New Entry".
+
+Each New Entry section will include a field for the entry's name, choice of icon (or option to download the service's favicon), "User Name", "Password", "URL", "Tags", "Notes", and option to "Set up one-time password (OTP)".
+
+Tapping the plus-sign button at the top will create a new custom text field for an entry. Enabling the "Protected Field" option on the lower-right will hide this field as if it was a password field. That being said, all fields from an entry will be fully encrypted with the database.
+
+<div class="grid" markdown>
+
+![Screenshot from the iOS app showing a New Entry page with various empty fields.](../assets/images/keepassium-review/keepassium-newentry.webp)
+
+![Screenshot from the iOS app showing the page within a Group with four different entries.](../assets/images/keepassium-review/keepassium-entries.webp)
+
+</div>
+
+An entry section from macOS:
+
+![Screenshot from the macOS app showing an entry section with the "User Name", "Password", "URL", "Tags", and "Notes" fields filled.](../assets/images/keepassium-review/keepassium-entrymac.webp)
+
+Finally, to edit, move, copy or delete an entry on iOS, a long press over its name from the directory will show these options. Swiping left on a password entry will also show the edit and delete options.
+
+![Screenshot from the iOS app showing the options Edit, Move, Copy, and Delete when long-pressing on a listed entry.](../assets/images/keepassium-review/keepassium-moveentry.webp){width="400"}
+
+### Password generator
+
+Conveniently, KeePassium includes a password generator. This is a common feature for password managers, and KeePassium implements this feature very well.
+
+The generator can be used from either the die-shaped button on the right of every password field, the tool-shaped button menu on the lower-left from inside a database selecting "Random Generator", or the die-shaped button on the lower-left from the "Databases" section. The latter is a nice touch if you ever need to generate a random string while your database is locked.
+
+Each time you open the Random Generator, it will automatically generate new random strings for all 3 modes: Basic, Expert, and Passphrase.
+
+<div class="grid" markdown>
+
+![Screenshot from the iOS app showing the tool menu from within a database. The menu shows options for "Random Generator", "Password Audit", "Download Favicons", "Print", "Change Master Key", "Encryption Settings", and "Lock Database".](../assets/images/keepassium-review/keepassium-databaseoptions.webp)
+
+![Screenshot from the iOS app showing the Random Generator page that displays three random passwords for "Basic", "Expert", and "Passphrase".](../assets/images/keepassium-review/keepassium-generator.webp)
+
+</div>
+
+The Random Generator can also be customized. To customize each mode, tap on the gears-shaped button on the upper-right of the generator and change the mode to adjust the parameters for each. The app will remember the parameters every time it is used.
+
+The customization for Passphrase does not include the options for "MIXED" case at this time, however, considering this option was just added to KeePassXC last month, maybe it will be added to KeePassium as well in the near future.
+
+![Screenshot from the macOS app showing the Random Generator page that displays the options to adjust for generated passphrase.](../assets/images/keepassium-review/keepassium-generatormac.webp)
+
+### One-Time Password (OTP)
+
+KeePassium offers the option to store one-time password codes with each entry. This can be a convenient way to manage second-factor of authentication, and keep these codes stored locally only.
+
+However, this can also introduce additional risks. If a database file was to get compromised at some point, it would also compromise all the OTP codes within it, making this second-factor protection useless against an attack of the whole database.
+
+If this isn't a risk you are concerned with, then KeePassium's OTP can be a useful feature.
+
+OTP codes are easy to set up and can be entered manually or using a QR code. Once set up, the code will be displayed as a field in the entry. Tap on it to copy it.
+
+<div class="grid" markdown>
+

+
+![Screenshot from the iOS app showing an Entry page with the option to "Set up one-time password (OTP)" selected at the bottom and displaying a menu with the options "Scan QR code" and "Enter manually".](../assets/images/keepassium-review/keepassium-otpentry.webp)
+
+</div>
+
+### AutoFill
+
+Depending on your usage, AutoFill can be an important feature for a password manager. AutoFill will allow KeePassium to recognize a login page and automatically fill all in the login credentials.
+
+To ensure AutoFill works smoothly, it's important to enter the correct website URL for each entry, specifically the page's URL where the credentials will be required.
+
+Ultimately, it's possible some websites will just not work with KeePassium's AutoFill. Some [issues](https://github.com/keepassium/KeePassium/issues/405) have been experienced while testing the app for this review. If you experience the same issue with a website, you can simply copy-paste the credentials manually in each corresponding field.
+
+<div class="admonition failure" markdown>
+<p class="admonition-title">AutoFill issues for some websites</p>
+
+A possible cause of AutoFill issues can be an incorrect entry URL that isn't the proper "Caller ID". To troubleshoot this, you can consult KeePassium's helpful [instructions](https://support.keepassium.com/kb/autofill-matching/) here.
+
+</div>
+
+#### AutoFill for iOS
+
+When set up correctly on iOS, a "Passwords" button should appear above the keyboard for websites where credentials have been stored in your database. If it doesn't, this could mean AutoFill was not set up properly from the [iOS Settings](https://support.keepassium.com/kb/autofill-setup-ios/).
+
+![Screenshot from a mobile browser with the login page for mastodon.social displaying empty credential fields and iOS showing a "Passwords" button over the keyboard.](../assets/images/keepassium-review/keepassium-autofill.webp){width="400"}
+
+#### AutoFill for macOS
+
+There isn't a browser extension available for KeePassium on macOS. The desktop AutoFill feature integrates with the system as a [credential provider](https://www.reddit.com/r/KeePassium/comments/1isvjjd/comment/mdsbwwc/). Browser implementation depends on how each browser integrates this function. The desktop AutoFill feature does work flawlessly with Safari.
+
+To set up AutoFill for KeePassium, you will have to enable it from the [macOS Settings](https://support.keepassium.com/kb/autofill-setup-macos/). KeePassium will guide you through the process with clear instructions to follow:
+
+![Screenshot from the macOS app showing a setting popup to "Uncheck Keychain" with the option to enable KeePassium instead.](../assets/images/keepassium-review/keepassium-autofillmac.webp)
+
+Once enabled, every website with a corresponding URL in your database will display a small key icon on the right of the credential fields.
+
+![Screenshot from Safari showing the cryptpad.fr login page and a key icon on the right of the Username empty field, with the option on the left to select either KeePassium or Keychain to fill the credentials.](../assets/images/keepassium-review/keepassium-loginsafarimac.webp)
+
+Despite lacking a browser extension, integration with Safari and the macOS ecosystem works smoothly, and it will work with applications that aren't browsers as well.
+
+![Screenshot from the ProtonDrive login popup in macOS showing a menu over the Password field to select either KeePassium or Keychain to fill the credentials.](../assets/images/keepassium-review/keepassium-loginappmac.webp)
+
+### Backups
+
+Backing up your database is essential with any KeePass-compatible app. Because there is no remote backup automatically stored by the application, you become responsible for protecting this data properly.
+
+KeePassium offers many options to help users back up their databases.
+
+#### Enable backup copies
+
+The option to back up local copies automatically will be enabled by default. You can disable it if you prefer (ideally not), or enable the option to "Show Backup Files" in "Settings" > "Database Backup". You can also adjust for how long you wish to keep the local backups (the default value is 2 months).
+
+#### Exclude from iCloud/iTunes
+
+There is an important feature to exclude your database file and KeePassium's backups of your database from your device's iCloud or iTunes backups. If you do not trust Apple with your encrypted database, you should enable this everywhere (excluding from iCloud/iTunes is disabled by default).
+
+If your database is stored locally (you might not see the option otherwise): From the "Databases" page, tap on the 3-dot button right to your database name (not the *circled* 3-dot button at the top, the one below). Then tap on "File Info" and *enable* the option "Exclude From iCloud/iTunes Backup" to make sure your database file stays outside your device's iCloud or iTunes backups.
+
+Secondly, to also exclude the backups created by KeePassium, inside a database tap on the "Settings" gear button on the lower-right, then "Database Backup", and *enable* "Exclude Backup Files from System Backup".
+
+<div class="grid" markdown>
+
+![Screenshot from the iOS app showing the File Info page for a database, with the "Exclude From iCloud/iTunes Backup" option enabled in green.](../assets/images/keepassium-review/keepassium-fileinfo.webp)
+
+![Screenshot from the iOS app showing the Database backup page from Settings with the "Exclude Backup Files from System Backup" option enabled in green.](../assets/images/keepassium-review/keepassium-backup.webp)
+
+</div>
+
+You will find the same option on macOS:
+
+![Screenshot from the macOS app showing the File Info for a database, with the "Exclude From iCloud/iTunes Backup" option enabled in yellow.](../assets/images/keepassium-review/keepassium-fileinfomac.webp)
+
+#### Auto-delete backup files
+
+You can choose the backup files to get deleted automatically after a certain period of time. For this, go to "Settings" then the "Database Backup" again, and scroll down to "Keep Backup Files". Select a retention period that is secure for your threat model. You can also tap on "Delete ALL Backup Files" below to delete all backups at any time.
+
+#### Manual backups
+
+Finally, you can simply back up your database `.kdbx` file manually. For this you have the options to transfer the file from KeePassium via cable, cloud storage, local network, AirDrop, email, or even Signal's [Note to Self](https://support.signal.org/hc/en-us/articles/360043272451-Note-to-Self)!
+
+To [transfer](https://support.keepassium.com/kb/database-transfer/) your database file entirely offline to another Apple device, connect your device together via USB cable and follow these [instructions](https://support.apple.com/en-gb/guide/mac-help/mchl4bd77d3a/mac).
+
+If you stored your database locally on iPhone, you will find the file in Apple's "Files" > "On My iPhone" > "KeePassium". From there, you can long press the file to see options to move or share it.
+
+![Screenshot from the iOS Files showing the menu from a long-press over the local database file with the option to "Move" the file circled.](../assets/images/keepassium-review/keepassium-movedatabase.webp){width="400"}
+
+#### Restore database from backup
+
+If you encounter any errors while managing your database, you can always restore it from a backup. Keeping multiple backup versions is a good idea to ensure you always have a functional file. Glitches and bugs are more likely to happen if you handle your database in unusual ways, with other software that may not have been tested for this usage yet.
+
+Restoring a database in KeePassium is a very straightforward operation. In the "Databases" section, tap on the 3-dot button on the upper-right, then select "Show Backup Files", if it isn't already on. Follow KeePassium's [instructions to restore](https://support.keepassium.com/kb/restore-backup/) a previous version.
+
+### Synchronization and direct connection
+
+While you can use KeePassium entirely offline, the app also offers options to synchronize your database with other KeePassium installations or other KeePass-compatible applications.
+
+There are two ways to do this. You can either simply store your database file in a cloud service of your choice and let KeePassium access this file, or you can use KeePassium's direct connection with certain cloud providers.
+
+You can see these two options from the app in "Settings" > "Network Access". From there, you have the option to select "Stay Offline", for maximum privacy, or "Allow Network Access", for maximum functionality.
+
+Whether you choose simple file synchronization or a direct connection, you can consult [this list](https://support.keepassium.com/kb/sync/) of cloud storage providers that have been tested by the KeePassium team and users to determine if your provider is supported.
+
+#### Stay offline, and synchronize through a cloud provider (recommended)
+
+This is KeePassium's [recommended method](https://keepassium.com/articles/cloud-sync-sandboxing/) to synchronize your database file(s) while maximizing privacy and minimizing external accesses. By default, KeePassium will remain offline, but you can store your database file with a cloud provider of your choice.
+
+This way, your cloud provider will manage the network communication, and KeePassium will only take care of decrypting your database. Because of system-enforced sandboxing, KeePassium will not have access to anything else on your cloud storage, only the database file(s) your have granted it access to.
+
+For example, you can store your database file on a cloud storage of your choice, then open it from KeePassium for iOS and also from KeePassXC on desktop. Both applications will access and manage the same file, therefore synchronizing your database.
+
+Be careful however when modifying your database. If synchronization isn't handled properly, this could cause errors that could corrupt your file. This is why it's important to test your setting first, and a good practice to keep a backup in a secure secondary location.
+
+![Screenshot from the iOS app showing the Network Access page with the option "Stay Offline" selected.](../assets/images/keepassium-review/keepassium-offline.webp){width="400"}
+
+<details class="example" markdown>
+<summary>Synchronization through Proton Drive</summary>
+
+Proton Drive isn't part of the recommended and tested list of cloud providers for KeePassium. However, it was briefly tested during this review.
+
+Between KeePassium iOS and KeePassXC on desktop, some synchronization was possible through Proton Drive, but with mixed results.
+
+To make it work, first the Proton Drive app needed to stay unprotected by a PIN or biometrics, which isn't ideal if you have other sensitive files on this drive. There was also some delay to sync the database between mobile and desktop, and a few bugs occurred while testing.
+
+That being said, synchronization was *possible* through Proton Drive between KeePassium for iOS and KeePassXC on desktop, but maybe not recommended. If you choose this setup for yourself, it is *strongly* recommended to conduct adequate testing first using a dummy database, and once set up with your actual database, to keep a secondary backup in a separate location.
+
+Testing couldn't make synchronization work between KeePassium iOS and KeePassium macOS through Proton Drive. Issues seem to come from conflict resolutions on the Proton Drive side. Of course, because Proton Drive isn't even listed by KeePassium as a supported storage, this was simply conducted as an experiment and not an expectation.
+
+Because many of our readers might use Proton Drive as a cloud provider, just be aware it probably isn't a usable synchronization solution at this time.
+
+Using Proton Drive to simply back up a password database file manually without synchronization is still a viable option, however.
+
+</details>
+
+#### Allow network access, to connect directly from KeePassium
+
+In 2022, KeePassium added direct connection options for certain cloud storage providers as a workaround solution for providers that were not integrating well with the system. This should however be a secondary choice only, as it will have some downsides for your data privacy.
+
+You can find this option from the "Data Encryption" welcome window at the start where you can either create a database, import a database, or "Connect to Server".
+
+Although KeePassium will only use what is necessary for this functionality, it [will access](https://keepassium.com/privacy/app/#direct-connections) more data than with the "Stay Offline" synchronization option. The data used for this functionality will however remain between your device and the cloud provider.
+
+#### Supported cloud storage providers
+
+KeePassium offers full support for iCloud Drive, Box, Dropbox, Google Drive, OneDrive, Resilio Sync, Nextcloud, SFTP / WebDAV, and limited support for Mega and Cryptomator.
+
+You might be able to make it work with cloud providers that aren't listed here. However, if you decide to use a provider that isn't fully supported, make sure to properly test your setup with a dummy database first.
+
+### Additional features
+
+This review focused testing on the most commonly used features that are accessible from a free plan. Nonetheless, KeePassium offers many more features, and additional ones for paid plans. Here's a summary of some other interesting features that have not been covered yet:
+
+#### Passkeys
+
+Since December 2024, KeePassium added [support](https://keepassium.com/blog/2024/12/keepassium-2.0/#passkey-support) for passkeys with its 2.0 release.
+
+#### Family sharing (Premium)
+
+You can use Apple's Family Sharing feature to [share](https://support.keepassium.com/kb/family-sharing/) your KeePassium paid license with your family members.
+
+#### Multiple databases (Premium)
+
+With a paid plan, it's possible to create or import multiple databases with KeePassium. This can be very convenient if you use a separate database for work and for your personal life, for example.
+
+#### Printing database
+
+KeePassium has a quick option to print an entire database in plain text, in an easy-to-read format. If this is secure for you, it can be a convenient way to keep a backup paper copy of all your passwords in case of emergency (or for inheritance purposes).
+
+To do this, while inside your database tap on the tool-shaped button on the lower-left, then select "Print". Of course make sure to secure this printed data *very well*, as it could be your weakest link.
+
+<div class="admonition warning" markdown>
+<p class="admonition-title">Important security warning!</p>
+
+Depending on your printer's settings, you should be *very careful* when using the print function. This data will be sent in plain text to your printer, and even perhaps through a network (depending on your printer's settings).
+
+This **can represent a very high security risk**, depending on your printer setup and situation. The file with your plain text passwords could also remain stored in the printer's queue!
+
+The print function can be [disabled](https://support.keepassium.com/docs/mdm-appconfig/#allowDatabasePrint) for users with a Business license.
+
+</div>
+
+![Screenshot from the iOS app showing a preview to print a database file in plain text. The file lists the database name at the top, then each group, and within each group all entries' credentials including usernames, passwords in plain text, URL, and notes.](../assets/images/keepassium-review/keepassium-print.webp)
+
+#### Read-only database
+
+You can protect a database from accidental changes by enabling this option. This will prevent any entries from being added, removed, or modified.
+
+It can be very useful if you have installed the app for someone who isn't comfortable with technology and want to make sure they cannot inadvertently delete an entry, for example.
+
+To enable it from KeePassium on iOS, go to the "Databases" section, long press on your database file, select "Database Settings", then enable "Read Only" at the top.
+
+#### File storage (attachments)
+
+You can use your database to store files!
+
+It's probably best to stay reasonable with this because files will quickly make your database very heavy. This could significantly slow down the encryption and decryption processes.
+
+That being said, it's a great way to store more sensitive files securely. The files will be encrypted with your database.
+
+You can either add files to an entry already created, or create a new entry named "Files" (or anything else you wish) to store all of your files together.
+
+To add a file, select the paperclip-icon tab at the top of an entry, then tap the plus-sign button at the bottom. Your files (attachments) will be accessible from any other KeePass-compatible application, like KeePassXC for example.
+
+![Screenshot from the macOS app showing the section tab within an Entry to add and view attachment files.](../assets/images/keepassium-review/keepassium-attachmentmac.webp)
+
+Interestingly, KeePassium even uses a quite decent PDF viewer on iOS:
+
+![Screenshot from the iOS app showing a preview for a PDF file, in this case the document for Privacy by Design by Ann Cavoukian.](../assets/images/keepassium-review/keepassium-pdfviewer.webp){width="400"}
+
+## :material-thumb-up-outline: Nice to have
+
+- You can see what was added, changed, or fixed for each KeePassium version from "Settings" in the "What's New" section.
+
+- You can change the KeePassium and database icons from "Settings" > "Appearance" > in "App Icon" and "Database Icons".
+
+- KeePassium has [excellent documentation](https://support.keepassium.com/)! This is handy to learn about features or to troubleshoot if you encounter any errors.
+
+- You can see the full credits for the app from "Settings" in the "About KeePassium" section.
+
+<div class="admonition question" markdown>
+<p class="admonition-title">Check the credits!</p>
+
+KeePassium not only credits its direct contributors but also lists credits for each graphics, code, and encryption algorithms used. You will find the same list of credits on KeePassium's GitHub [page](https://github.com/keepassium/KeePassium?tab=readme-ov-file#author-and-credits). This is a wonderful idea that more software should get inspired by.
+
+</div>
+
+## :material-thumb-down-outline: Downsides
+
+Even if KeePassium is a great secure application that is easy and pleasant to use, there are still a few downsides that should be mentioned:
+
+- People with older versions of iOS or macOS will unfortunately not be able to use the application at all.
+
+- KeePassium only works in the Apple ecosystem, and there are no versions for other systems at this time.
+
+- If you are using a cloud provider that doesn't work smoothly with KeePassium and you need synchronization, you will unfortunately need to synchronize your database manually or change your cloud storage provider.
+
+- AutoFill on iOS might not work for every account. This can be an inconvenience depending on your usage and which of your accounts (if any) are impacted.
+
+- AutoFill on macOS might not work with your favorite browser (if it isn't Safari).
+
+## :octicons-key-16: Conclusion
+
+Overall, KeePassium is a privacy-focused, offline-first application, that has clearly prioritized user experience and user interface, while not neglecting security and privacy.
+
+When used with the basic and supported settings, it works fairly smoothly and allows enough customization to adapt to a variety of user needs and situations.
+
+The fact that KeePassium allows full compatibility with most other KeePass-compatible applications is an immense benefit compared to proprietary password managers.

+  Privacy Pass is a new way to privately authenticate with a service. Let's look at how it could change the way we use services.
+---
+# Privacy Pass: The New Protocol for Private Authentication

+
+Services that require authentication can correlate your activity on that service with your account, and that account is normally linked with payment information that could potentially link back to your real identity. With the Privacy Pass protocol, it doesn't have to be that way.<!-- more -->
+
+## History
+
+The story of Privacy Pass begins with a [paper](https://dl.acm.org/doi/pdf/10.1145/4372.4373) by David Chaum from 1985 (he actually has an earlier paper from [1982](https://chaum.com/wp-content/uploads/2022/02/chaum_dissertation.pdf), but I'll be referencing this one), in which he laments the ever-increasing data collection by companies and government agencies.
+
+It's funny that all the way back in 1985 he talks about the same issues we deal with today: persistent identifiers tied to our real identity for transactions, government IDs, etc.
+
+Chaum proposes three solutions to the state of affairs he describes.
+
+### Pseudorandom Identifiers
+
+Instead of persistent identifiers like we now have with our government IDs, credit cards, etc., Chaum suggests randomly generated identifiers. For example, you could have a one-time unique identifier for each transaction at a shop.
+
+For ongoing relationships such as a bank, you can use a single pseudorandom identifier for that organization that you use continuously.
+
+### Card Computers
+
+One of the more quaint ideas in the paper is the idea of a small "card computer" on which you would perform transactions. Chaum's theoretical device resembles "a credit-card-sized calculator, and [includes] a character display, keyboard, and a limited distance communication capability (like that of a television remote control)".
+
+Nowadays, we carry around credit-card sized computers like it's nothing. The secret "card number" he describes would probably be your device PIN or even biometric authentication, which are already used to authenticate transactions.
+
+We still haven't *quite* reached Chaum's vision yet in some areas. His idea is for these "card computers" to fully replace ATMs and checkout terminals in stores. Essentially, he wants all transactions to be online transactions, with something like Apple Pay or Google Pay on your device mediating the transaction and using your device PIN to prevent fraudulent transactions.
+Making all transactions online transactions is an interesting idea. I think most people can share in the frustration of dealing with checkout terminals, especially the self-checkout ones with cameras pointed at your face.
+
+We're still falling short in a major area though.
+
+> card computers could be purchased or constructed just like any other personal computer, and would have no secrets from or structures unmodifiable by their owners.
+
+Current smartphones are non-upgradeable by their owners and can't be built from scratch like a desktop computer can. They also contain lots of black-box proprietary code. Even a Google Pixel, the gold standard of Android smartphone freedom that allows you to install your own operating system securely, still suffers from the same pitfalls.
+
+### Cryptography
+
+How do we ensure the pseudonyms can't be linked together? We already use cryptography to protect our communications. Chaum presents ways to similarly protect unlinkability using cryptography:
+
+> Simple mathematical proofs show that, with appropriate use of the systems, even conspiracy of all organizations and tapping of all communication lines cannot yield enough information to link the pseudonyms-regardless of how clever the approach is or how much computation is expended.
+
+## Blind Signatures
+
+Digital signatures normally are used to ensure that something like a piece of software or a message comes from the original sender and hasn't been tampered with. You want to know who the signer is for this system to work.
+
+But what if the signer and the one sending a request are different? Say you have a membership to a hypothetical *PrivacyGuides+ subscription service*, and you want to authenticate with it, but don't want to identify yourself. That's where blind signatures come in.
+
+### How it Works
+
+You can imagine blind signatures like an envelope that's been wrapped in [carbon paper](https://en.wikipedia.org/wiki/Carbon_paper) with a window showing your pseudonym for that account, whether it be an account number, username, etc. They never see anything but the account identifier, or whatever they need to verify that you're a valid customer.
+The organization then signs it, indicating you're a valid customer, and you're allowed to access the service.
+
+Later, when you're presented with a request to authenticate as an active subscriber of PrivacyGuides+, you unwrap the envelope and discard it along with the carbon paper. You rewrap it in a new envelope with a window showing the signature and a different pseudonym, and the requester can then be sure that you're allowed to access PrivacyGuides+.
+
+![A diagram showing an envelope being wrapped in carbon paper, transferred to an organization, then passing over a boundary representing the unlinkability between the two transactions. Then the envelope is unwrapped, put in a new envelope with a window showing the signature from the previous organization, and presented to a different organization.](../assets/images/privacy-pass/blind-signatures.webp)
+
+<small aria-hidden="true">Illustration: [David Chaum](https://dl.acm.org/doi/pdf/10.1145/4372.4373)</small>
+
+This system relies on the same strong cryptography that tried and true systems use, with the difference being the unlinkability between the credential issuer and the credential receiver.
+
+## Problems
+
+Services that don't require an account or payment to use are great; you can use them with Tor, clear your browser history, whatever you need to do to keep your activity private.
+
+But logging into an account completely invalidates all of that. Every time you log in or authenticate with a service, you have to identify yourself as the same person, linking all your previous activity together. Increasingly, we're asked to provide personal information in order to be able to use certain websites or services.
+
+### Linkability
+
+As long as you're logged into an account with a service, all your previous and current activity can be linked together, along with any data you provided such as an email address, payment information, etc.
+
+### Data Collection
+
+A lot of websites and services want to — [or are forced to](https://en.wikipedia.org/wiki/Social_media_age_verification_laws_in_the_United_States) — filter out users below a certain age.
+
+We're starting to see a rise in extremely privacy-invasive age verification systems such as submitting a government ID when you want to access a website or invasive facial scans.
+
+### Blocking VPN and Tor Users
+
+Bots are a rampant problem for online services, leading them to sometimes block non-residential IP addresses such as those used for commercial VPNs and Tor.
+
+### CAPTCHAs
+
+When VPN and Tor users aren't blocked, they often have to deal with annoying [CAPTCHAs](http://www.captcha.net) that take up your precious time and use invasive [fingerprinting](https://developers.google.com/recaptcha/docs/v3).
+
+CAPTCHAs aren't even particularly good at detecting bots. With advances in AI, [bots can solve CAPTCHAs better than humans can](https://arxiv.org/pdf/2307.12108).
+
+## Privacy Pass
+
+Several blind signature-based solutions are in various states, some being implemented but not widely used, some being proposed browser APIs, and some being IETF standards.
+
+The landscape is very confusing right now, so I'll try to elucidate what I've found.
+
+[Privacy Pass](https://privacypass.github.io) started out as an attempt at a privacy-preserving way to bypass CAPTCHAs.
+
+It started out and is still an extension that can be installed on the [Chrome](https://chromewebstore.google.com/detail/silk-privacy-pass-client/ajhmfdgkijocedmfjonnpjfojldioehi) or [Firefox](https://addons.mozilla.org/en-US/firefox/addon/privacy-pass/) extension store, but it's since expanded to become an [IETF standard](https://datatracker.ietf.org/wg/privacypass/about/).
+
+The Privacy Pass protocol has massively outgrown its original purpose. It's been updated to support multiple different schemes and purposes.
+
+There are three main roles that need to be played for the authentication mechanism to work. These can be filled by all the same party, by three separate parties, or any combination in between. You'll have increased privacy the more separation there is between each role, so ideally they should all be filled by different parties.
+
+### Origin
+
+The origin is the original website or service that's requesting a token for redemption. The client presents a valid token, or it must request more tokens.
+
+### Attester
+
+The attester is responsible for verifying something about the client. There are several ways it can achieve this, and it can use multiple at the same time if desired.
+
+#### CAPTCHA
+
+The attester can make the client solve a CAPTCHA to prove that it's not a bot. Not the most elegant solution but solving one CAPTCHA instead of multiple is preferable.
+
+#### Client State
+
+The attester can verify something about the client's state like the geographic location, whether the client has a valid account, or the number of issuance protocol invocations.
+
+#### Trusted Device
+
+If your client is running on hardware that's capable of producing device-level attestation, like a device with a secure element, then it can use that to verify that the device is trusted.
+
+For example, in Apple's Private Access Token implementation, they use certificates stored in the Secure Enclave and verify that your Apple account is in good standing.
+
+### Issuer
+
+The issuer is responsible for issuing tokens in response to requests from clients.
+
+The client presents tokens to the Origin once they're provided by the issuer.
+
+![diagram showing the structure of Private Access Tokens. The origin asks the client for a token, the client forwards the request to the attester which then forwards it to the issuer which then generates a token, sends it to the client which then sends it to the origin.](../assets/images/privacy-pass/private-access-tokens.webp)
+
+<small aria-hidden="true">Illustration: [Cloudflare](https://blog.cloudflare.com/eliminating-captchas-on-iphones-and-macs-using-new-standard/)</small>
+
+The tokens need to identify which issuers are trusted.
+
+They can also be interactive or non-interactive. Interactive means that you need a fresh token based on the challenge, whereas a non-interactive token can be stored for later use.
+
+Tokens can also be constrained to one specific Origin, or they can be used across Origins.
+
+### Private State Tokens
+
+[Private State Tokens](https://developers.google.com/privacy-sandbox/protections/private-state-tokens) (PSTs) are a [proposed browser API](https://github.com/WICG/trust-token-api) by Google as part of their [Privacy Sandbox](https://developers.google.com/privacy-sandbox). They're based on the Privacy Pass protocol.
+
+The main benefit of PSTs is that they provide a secure place for websites to store their tokens so that you don't need a separate extension for every service.
+
+A browser-level API, I imagine, would significantly reduce the development burden of browser-based services looking to implement Privacy Pass, but it would leave non-browser apps like VPNs high and dry.
+
+### Private Access Tokens
+
+[Private Access Tokens](https://blog.cloudflare.com/eliminating-captchas-on-iphones-and-macs-using-new-standard/) are based on Privacy Pass as well, but they don't seem to be specifically bound to the browser.
+
+It's unclear to me what really makes Private Access Tokens different from Privacy Pass itself, other than that Private Access Tokens seem to call for separation of the Attester and Issuer while Privacy Pass allows the origin, attester, and issuer to be the same. Delegating each role to a different party adds extra privacy.
+
+The origin website only knows your URL and IP from the initial connection.
+
+The attester only knows the data needed to verify you as a valid user.
+
+The issuer knows the site you visited, but doesn't know any of your device information that the attester used to verify you.
+
+### Kagi
+
+There are scant services actively using Privacy Pass to authenticate users, but a recent and very exciting example is [Kagi](https://blog.kagi.com/kagi-privacy-pass).
+
+With their implementation, you can now install their extension for [Firefox](https://addons.mozilla.org/en-US/firefox/addon/kagi-privacy-pass/) and [Chrome](https://chromewebstore.google.com/detail/kagi-search/cdglnehniifkbagbbombnjghhcihifij). Safari isn't supported at the moment, but their [Orion](https://chromewebstore.google.com/detail/kagi-search/cdglnehniifkbagbbombnjghhcihifij) browser supports it and is WebKit-based.
+
+The need for an extension and lack of support for some platforms highlights the need for widespread support for Privacy Pass in browsers and platforms. It's not reasonable to expect every single platform to implement Privacy Pass themselves and users likely don't want to install a separate extension for every platform either.
+
+That said, I applaud Kagi for their efforts. They went above and beyond to protect their users' privacy. A few notes for future improvements, though.
+
+#### No Account Requirement
+
+Currently, Kagi requires an account in order to use it. Although they allow you to put in a fake email address on account creation since they don't [check it](https://kagifeedback.org/d/3813-enable-anonymous-registration-no-email/16), it's still a persistent identifier that could be eliminated.
+
+Their announcement blog post states that the ability to use Kagi fully without an account is a possibility for the future with an invitation to request the feature on their [forum](https://kagifeedback.org/d/6163-kagi-privacy-pass), so feel free to add your voice. A fully accountless search engine that doesn't rely on ads would be great to see.
+
+#### Separation of Origin, Attester, Issuer
+
+Kagi uses the [Shared Origin, Attester, Issuer](https://www.ietf.org/archive/id/draft-ietf-privacypass-architecture-03.html?_fsi=jKxFixnl#section-4.1) model for their implementation, which leaves the possibility of data being correlated between each step of the process, such as device fingerprinting or IP address being used to correlate a user who is issued tokens with when they redeem them.
+
+Kagi's onion service helps to mitigate this issue, but I think it would be a significant privacy improvement to separate all three entities.
+
+#### Remove Requirement for an Extension
+
+Having to install an extension is annoying as an end user and surely incurs some development cost in both the initial development and upkeep over time. I'm not sure how it would be possible to get rid of the extension as it seems like there's no good way to do so at the moment, but I'm hopeful that the Private State Token API could be used for that in the future if it ever gets fully standardized as a browser API.
+
+## Future Possibilities
+
+Overall, Privacy Pass is an exciting standard that is already improving the privacy of users on a wide scale.
+
+### Easier Adoption
+
+However, for widespread adoption of anonymous authentication for all online services, there needs to be an easier way for developers to implement it. I see Private State Tokens and Private Access Tokens as paths toward that goal, but they have their own limitations.
+
+Private State Tokens seem to be restricted to browsers, which is mostly fine since so many online services are accessed through the browser. It does put services like VPNs that operate outside the browser in a tight spot though.
+
+Private Access Tokens seem like a possible solution for device-wide Privacy Pass authentication, but the only place I've seen them implemented is in Apple's operating systems to identify users as real iOS or macOS users. I'd like to see wider adoption for more use cases than just that. It's unclear what the vision for Private Access Tokens is for the moment.
+
+### Carriers
+
+One of the biggest and most privacy-invasive services is mobile carriers. They take lots of personal information when you sign up, and then you have permanent identifiers, both IMSI identifying you as a subscriber and IMEI identifying your device, tied to that information while you use it. Because of how the cell network works, they also can tie that information to your physical location and all the traffic you send through their network.
+
+[Cape](https://www.cape.co/research) is a privacy-focused carrier that says they're "studying the use of blinded tokens and zero-knowledge proofs to disaggregate subscriber information." This would have a massive impact on user privacy, possibly allowing a KYC'd mobile subscriber to use their carrier at least semi-anonymously (it's unclear how IMSI and IMEI fit into this scheme, as well as location information).
+
+### VPNs
+
+Commercial VPNs typically require some kind of account identifier, even if it's just a randomized number.
+
+Apple's iCloud Private Relay uses RSA blind signatures to anonymously authenticate users to each of the two hops.
+
+Google's former [VPN](https://www.gstatic.com/vpn/google_vpn_white_paper.pdf) service also used blind signatures to protect users.
+
+![Diagram showing Google's blind signature VPN authentication scheme](../assets/images/privacy-pass/google-vpn.webp)
+
+<small aria-hidden="true">Image: [Google](https://www.gstatic.com/vpn/google_vpn_white_paper.pdf)</small>
+
+Hopefully we can see more VPN companies start to use Privacy Pass to authenticate users, I think it would be a massive improvement to user privacy.
+
+### Digital Cash
+
+Part of Chaum's vision was anonymous digital transactions using blind signatures, which he made a reality with his company [DigiCash](https://chaum.com/wp-content/uploads/2022/01/05-27-94-World_s-first-electronic-cash-payment-over-computer-networks.pdf).
+
+For whatever reason, *eCash*, as it was called, never caught on and the company filed for bankruptcy in 1998. We're left with the terrible current system where you need to input your credit card and personal information in order to make a transaction, which is easily traceable back to you. Not to mention the security implications, [credit card fraud](https://www.security.org/digital-safety/credit-card-fraud-report/) is rampant today.
+
+The dream isn't dead, however. Chaum's [eCash 2.0](https://chaum.com/ecash-2-0/) is quantum-resistant and has been built and tested in the Bank for International Settlements' [Project Tourbillon](https://www.bis.org/about/bisih/topics/cbdc/tourbillon.htm).
+
+### Digital ID
+
+Laws are being passed forcing 18+ websites and even [app stores](https://thehill.com/policy/technology/5179865-utah-app-store-age-verification-law/) to collect verify the ID of users. This is a massive slap in the face to the privacy and security of everyone. Data breaches and tracking are inevitable under the current system.
+
+Blind signatures could provide a private and secure way to verify age or other information without having to submit your entire ID or submit invasive face scans.

+
+Last week, OpenAI's CEO Sam Altman announced in San Francisco that the World project he co-founded, formerly known as Worldcoin, is opening six stores across the United States, allowing users of the project's app to scan their eyeballs.
+
+Simply put, the premise is this: scan your eyeball, get a biometric tag, verify yourself, buy our apps (and cryptocurrency). The scary part is the for-profit company developing the project has now gathered millions in venture capital investment, powerful partners, and is ready to expand and impose its [Minority Report](https://en.wikipedia.org/wiki/Minority_Report_(film)) style technology everywhere. **Welcome to Dystopialand.**<!-- more -->
+
+The World(coin) project is an initiative from the startup Tools for Humanity, co-founded by its CEO Alex Blania. Despite its friendly name, the for-profit corporation has been on the radar of many critics through the years already. From experts to journalists to privacy commissioners around the world, not everyone shares Blania's enthusiasm for his biometric-based technology.
+
+## What is the World App?
+
+The World project, recently rebranded from the Worldcoin project (possibly to convey better its expansionist ambitions) presented its plan for the World App to Americans this week. The project is now expanding well beyond the cryptocurrency it started from.
+
+The World App is an everything app, providing users with a *World ID*, that can be verified through the collection of biometric data in the form of an iris scan.
+
+The scan is then filtered and hashed to create a unique identifier that is stored as a so-called "proof of personhood" on the *World Network*, a blockchain-based protocol.
+
+The World App itself contains a collection of "Mini Apps", where users can manage their cryptocurrencies, chat together, play games, receive their pay check even, and ultimately live their whole life within the closed "verified" ecosystem of the app.
+
+For a company constantly praising decentralization, it sure looks like they want to make sure they are the center of it all.
+
+To obtain this coveted verification code, users *must* be ready to share their precious eyeball data with the Orb.
+
+The Orb is a piece of hardware designed by Tools for Humanity to perform iris scans. It is available to access in the United States at one of the currently six locations in Austin, Atlanta, Los Angeles, Miami, Nashville and San Francisco (more to come soon), like some sort of biometrics collection ATM.
+
+The World project has for ambition to expand its reach across the United States to install 7,500 Orbs by the end of this year, so be prepared to see this dystopian technology everywhere soon.
+
+The San Francisco [presentation last week](https://www.theregister.com/2025/05/04/sam_altman_startup_world/) was clearly prepared to impress investors with its Apple announcement vibe. The promise of a quickly growing startup that everyone will soon want to work with, was repeated over and over in different flavors.
+
+Tools for Humanity bragged about many large partnerships that should make any privacy advocates shiver in dread: the Match Group dating apps conglomerate (Tinder, OkCupid, Hinge, Plenty of Fish), Stripe, and Visa are some of them.
+
+If they succeed in convincing enough people, many of us could soon have little choice but to unwillingly have to enroll.
+
+## World(coin) isn't new, you might have heard of its unethical practices already
+
+The project [claims](https://techcrunch.com/2025/04/30/sam-altmans-world-unveils-a-mobile-verification-device/) to have onboarded 26 million people already, including 12 millions "users" who are verified (had their biometric data collected).
+
+These "users" are largely located in Latin America, Africa, and Asia. This is because the company started testing for its project there a few years ago, in regions where people often have fewer legal protections.
+
+In 2022, MIT Technology Review produced [an extensive investigation](https://www.technologyreview.com/2022/04/06/1048981/worldcoin-cryptocurrency-biometrics-web3/) on the startup's debut in an article titled: *Deception, exploited workers, and cash handouts: How Worldcoin recruited its first half a million test users.*
+
+The investigation revealed a collection of unethical practices to pressure the most vulnerable populations in signing up for Worldcoin, and **have their eyeball scanned in exchange for money** they desperately needed.
+
+Some participants had to provide much more personal information than the company says is required, such as emails, phone numbers, and even photos of official ID. Many people who gave their biometric data to Worldcoin were rushed and misinformed. Some who signed up didn't even have an email and had to create one. The "Orb operators" hired to perform the scans locally were often poorly trained, poorly informed, and unable to answer the questions asked by participants.
+
+So much so that [Kenya suspended the company's operations](https://techcrunch.com/2023/08/02/kenya-suspends-worldcoin-scans-over-security-privacy-and-financial-concerns/) in 2023 over concerns for privacy, security, and financial service practices.
+
+Some people who signed up never received the promised money. Some officials were bribed to give the impression to participants these operations were official and supported by the government.
+
+As Ruswandi, one of the person targeted by this early campaign [remarked](https://www.technologyreview.com/2022/04/06/1048981/worldcoin-cryptocurrency-biometrics-web3/): "why did Worldcoin target lower-income communities in the first place, instead of crypto enthusiasts or communities?"
+
+Exploiting people in situation of poverty in order to test a biometric identification technology isn't a great way to start a project developed by a company called "Tools for Humanity".
+
+## Creating the problem, selling the solution
+
+Why developing such a technology in the first place?
+
+Sam Altman himself have [expressed concern](https://www.wired.com/story/sam-altman-orb-eyeball-scan-launch-us/) about the problem this alleged solution solves: the avalanche of fake accounts and pretend persons online caused by the new AI tools unleashed everywhere.
+
+The proposed use of a "proof of personhood" claims to solve this problem by allocating a unique identifier to each human, a personal code supposedly impossible to duplicate or cheat. Of course, this has [already been proven wrong](https://gizmodo.com/worldcoin-black-market-iris-data-identity-orb-1850454037).
+
+No one will miss the irony of the CEO of OpenAI, responsible for creating the largest share of this problem, expressing such concern **while continuing to feed the fire**.
+
+This is a classic case of creating a problem and selling the solution. Well, in this case it is more like ***selling* the problem and selling the solution**. As researcher and cryptocurrency critic [Molly White pointed out](https://www.citationneeded.news/worldcoin-a-solution-in-search-of/) in 2023:
+
+"That's right, the guy who's going to sell us all the solution to a worsening AI-powered bot infestation of the Internet and to AI-induced mass unemployment is the same guy who's making the AI in question."
+
+Sadly, this proposed solution also isn't really a solution, or at least it isn't a *good* solution. Indeed, this will **create a whole collection of new problems**, many much worse than a bot infestation.
+
+## The risks of sharing biometric data
+
+Biometric data is incredibly sensitive data, because it's irrevocably attached to a person. Whether it's from a face scan, palm scan, fingerprint, keystroke pattern, or iris scan, this data is part of our bodies and **cannot be changed like a password** if it gets compromised.
+
+For this reason, a growing number of legislations around the world now include special categories for such data collection, and require extra protections and supervision for it.
+
+There are many dangers in collecting and potentially endangering biometric data. First, if this data gets stolen, criminals can impersonate a victim much more convincingly, because they will have the "proof" to "verify" this is really you.
+
+While straight-up stealing your eyeball or face might still belong to science-fiction, the risk of getting the data produced *from* the scan stolen is very real.
+
+When the World project claims it is secure because biometric data isn't stored anywhere, even if that was true, the iris *code* derivative of this data is indeed stored and processed somewhere, and this can potentially be stolen.
+
+How hard will it be for a victim to recover an account from a biometric thief when everything is reinforcing the false narrative shared with investors that this technology can't be cheated?
+
+Then, there is the loss of pseudonymity protections online.
+
+If every social media account becomes tied to a unique biometric-based identifier, whether directly or indirectly, there is no pseudonymity anymore.
+
+Further, if only one account is allowed by "verified human", then no one can create separate accounts for their work life and personal life anymore. Creating separate accounts for separate purposes is an excellent privacy-preserving practice.
+
+Even if the identifier isn't tied to a legal name directly, accounts on different platforms using the same identifier could potentially get liked together. To be fair, it does seem Tools for Humanity worked to prevent different platforms from having access to the same code, but how well will this hold the test of time? Will platforms increasingly escalate privacy-invasive requests from this point, like they often do?
+
+**Pseudonymity saves lives.** It is an essential tool for the safety of the most vulnerable online. Killing pseudonymity by requiring unique biometric identification could endanger millions.
+
+This is a serious problem coming up with [age verification](age-verification-wants-your-face.md) processes as well, which World ID will soon also be a part of when [testing](https://www.engadget.com/cybersecurity/sam-altmans-eyeball-scanning-id-technology-debuts-in-the-us-130032856.html) its implementation for Tinder in Japan.
+
+Biometric data should never be used lightly. It should be reserved for the most extreme cases only.
+
+The regions who have adopted stronger regulations for biometric data collection are moving in the right direction. But will protective legislation be enough to resist the pressure from a for-profit VC-backed corporation with a valuation at billions?
+
+## Flipping the coin
+
+Tools for Humanity seems to be well aware of its creepiness factor, and of the criticisms brought by privacy commissioners around the world.
+
+Its recent Orb redesign from the previous cold (Black)mirror finish clearly tries hard to replace creepiness with cuteness.
+
+The company has also evidently invested a lot in presenting a pro-privacy image, likely in an attempt to reassure users (and investors).
+
+Unfortunately, many of these privacy-preserving claims are inaccurate. Some claims promoting "features" that might sound impressive to a neophyte's ear are actually just the baseline, and others sadly are misleading *at best*.
+
+While a few privacy-preserving efforts are indeed positive, most of the focus on privacy relates to marketing much more than any serious protections.
+
+## How privacy-preserving is it?
+
+Most people are still put off by the idea of having their eyeball scanned, and the company has evidently invested a lot in promoting a "privacy-preserving" image, possibly as an attempt to reassure unconvinced humans and [privacy commissioners](#privacy-legislators-arent-on-board) alike.
+
+But how much can we trust those claims?
+
+### Flawed assumption about what constitutes personal data
+
+The largest assumption about why this technology is "privacy-preserving" seems to come from the fact that the World App doesn't collect names, official IDs ([unless it does](https://www.toolsforhumanity.com/legal/privacy-notice#6-2-credentials-)), emails ([unless it does](https://www.toolsforhumanity.com/legal/privacy-notice#annex-i-%E2%80%93-legal-grounds/purposes-for-tools-for-humanity-data-processing-activities-)), phone numbers ([unless it does](https://www.toolsforhumanity.com/legal/privacy-notice#5-1-data-you-provide-to-us)), date of birth ([unless it does](https://world.org/blog/announcements/worldcoin-new-world-id-unverify-option-increases-personal-control-over-data)), or other identifiers.
+
+This assumption however neglects the fact that 1) even data that isn't attached to a legal name can be personal data, and 2) the iris code it produces from the iris scan *is* indeed personal data.
+
+While there are variations, most privacy regulations have similar definitions of what constitute personal data. The European General Data Protection Regulation (GDPR) [defines](https://gdpr-info.eu/art-4-gdpr/) it as "any information relating to an identified or identifiable natural person". An iris code derived from an iris scan of course fits this definition.
+
+Moreover, to create a World ID, the company also collects a face image. Together, the original iris scan and face photo are referred to as *Image Data*. For "privacy-preserving" purposes, Image Data of course never leaves the Orb device ([unless it does](https://world.org/legal/biometric-data-consent-form)).
+
+While it seems some effort has been made to protect the Image Data in some ways, the idea that derivative data from the scans isn't still sensitive personal information anymore is wrong.
+
+If there is a way for a person to scan their iris again and generate the same code, then this data relates to their identifiable person. This also means that *someone else* could scan their iris and generate the same code.
+
+As whistleblower [Edward Snowden rightfully pointed out](https://x.com/Snowden/status/1451990496537088000) in a 2021 tweet:
+
+“This looks like it produces a global (hash) database of people's iris scans (for 'fairness'), and waves away the implications by saying 'we deleted the scans!' Yeah, but you save the *hashes* produced by the scans. Hashes that match *future* scans. Don't catalogue eyeballs.”
+
+### Questionable reassurance about local data
+
+One of the biggest reassurance relates to the claim that sensitive biometric data (Image Data) is only stored locally. But this isn't completely accurate either, and there seems to be conflicting information about it from the company's own documentation.
+
+The World [white paper](https://whitepaper.world.org/#enrollment-process) specifies that:
+
+"The Orb verifies that it sees a human, runs local fraud prevention checks, and takes pictures of both irises. The iris images are converted on the Orb hardware into the iris code. Raw biometric data does not leave the device (unless explicitly approved by the user for training purposes)."
+
+However, according to the [Biometric Data Consent Form](https://world.org/legal/biometric-data-consent-form) users have to sign prior to data collection, if a user needs a fully verified World ID, inevitably this sensitive biometric data will be sent to their phone, therefore leaving the Orb.
+
+After a user agrees to the form, they can keep the option for *Data Custody* disabled to have their biometric data deleted from the Orb "later", and have it uploaded to their phone (with all the risk that this entails).
+
+The other option users have is to enable Data Custody (if allowed in the user's country) and have this sensitive data sent to both their phone *and* to Tools for Humanity.
+
+This means the Orb inevitably sends this sensitive data to a mobile device. Then, this data is only as secure as the mobile device is. Which isn't so reassuring.
+
+The documentation does maintain this biometric data is sent as an "end-to-end encrypted data bundle", but this doesn't mean the data never leaves the Orb, it just means it leaves it while encrypted (which is really just the basics), and copies it to the user's device.
+
+Furthermore, future users are *strongly* incentivized to share their Image Data with Tools for Humanity, for algorithm improvement purposes. Pressure to opt in is even presented as a *convenience* option, because it would be cumbersome to have to come over for another scan after every update.
+
+As [stated](https://world.org/legal/biometric-data-consent-form) in the Biometric Data Consent Form:
+
+"This will likely help you avoid some inconvenience because, if we have your Image Data, then you will not need to return to an Orb to re-verify your digital identity when we update the software."
+
+The company continues to repeat they have a "privacy by default and by design approach". But **you can't keep your privacy-preserving cake and eat it, too**.
+
+### What does the white paper say
+
+In tech, a white paper is usually a research-based document produced by the developers that presents more technical details on an application, product, or process. It is especially valuable for products like the Orb and the World App, where security and privacy *should* be paramount, and therefore examined closer.
+
+Because it isn't an independent review, a white paper can also not be worth much more than a marketing pamphlet.
+
+To its credit, Tools for Humanity does [warn](https://whitepaper.world.org/#nature-of-the-whitepaper) in its white paper that this information is "intended for general informational purposes and community discussion only and do not constitute a prospectus, an offer document, an offer of securities, a solicitation for investment, or any offer to sell any product, item or asset (whether digital or otherwise)."
+
+Furthermore, the company makes sure to specify that "circumstances may change and that the Whitepaper or the Website may become outdated as a result; and the [World] Foundation is not under any obligation to update or correct this document in connection therewith."
+
+The document is also described as a "crypto-asset white paper".
+
+We have been warned.
+
+In its Privacy section, the white paper [states](https://whitepaper.world.org/#image-custody-opt-in) that "no data collected, including images taken by the Orb has or will ever be sold. Nor will it be used for any other intent than to improve World ID."
+
+However, its [Privacy Notice also states](https://world.org/legal/privacy-notice#8--when-we-share-your-data) that they may "share your personal information in connection with, or during negotiations concerning, any merger, sale of company assets, financing, or acquisition of all or a portion of our business by another company."
+
+If this happens, many regretful users might find themselves in [the same shoes as 23andMe users this year](https://www.techradar.com/health-fitness/23andme-is-bankrupt-and-about-to-sell-your-dna-heres-how-to-stop-that-from-happening), where the DNA collecting company started to look for buyers of its biometric data assets after filling for bankruptcy.
+
+Additionally, the Face Authentication section of the white paper [describes](https://whitepaper.world.org/#face-authentication) a process where encrypted facial biometrics collected from the Orb are used for authentication in the World App.
+
+Even if this data is stored on-device, it is still biometric data getting collected by the Orb then processed by the phone app. There is no question this is sensitive and personal biometric data, and it is indeed kept outside the orb.
+
+Tools for Humanity lacks consistency in the various claims and statements found through its documentation and promotion material. It becomes difficult to know which version to trust, and if it is to be trusted at all.
+
+### No deletion on the blockchain
+
+Tools for Humanity's Privacy Policy declares that the company will delete all account data (when laws allow it) one month after it is closed, this is good. They also state they will delete entirely any inactive account after 2 years, and this is actually a great policy.
+
+But what happens to the World ID, transactions, and other data stored on the blockchain?
+
+While some thoughts have been put into deletion and some good mechanisms seem to have been implemented, unfortunately data stored on the blockchain might be "deletion-resistant".
+
+There's a possibility that **what happens on the blockchain stays on the blockchain, forever**.
+
+The policy [notes](https://www.toolsforhumanity.com/legal/privacy-notice#11--how-long-do-we-keep-your-data-) that:
+
+"Due to the public and immutable nature of blockchain technology, we cannot amend, erase, or control the disclosure of data that is stored on blockchains."
+
+So that is something to keep in mind if you value your right to delete.
+
+## Data security considerations
+
+Even if some thoughtful security features seem to have been implemented for the World App and its Orbs, nothing processing sensitive data at such a large scale should be left in the hands of a single for-profit, largely unregulated, organization.
+
+This would be like putting 8 billion eggs in a very fragile basket, held by someone paid to make the basket pretty and convince as many people as possible to put their precious single egg in it, with no incentive whatsoever to ensure the basket doesn't break. I would not want to put my egg in there, especially with how much it costs now.
+
+The idea of using one single *for-profit* app worldwide for "human verification", identity verification, age verification, money transactions, and storing official IDs (and so on and so forth) makes this application a *huge* target for criminals and hostile governments alike.
+
+It's good that the app had [security audits](https://github.com/trailofbits/publications/blob/master/reviews/2023-08-worldcoin-orb-securityreview.pdf), made some [code available](https://github.com/worldcoin) as open source, and reportedly [plans](https://whitepaper.world.org/#why-custom-hardware-is-needed) to open a bug bounty program.
+
+However, there are still problems that remain. For example, the phone in this case becomes a single point of failure. The easiest way to steal someone's identity and money (all at once) will be to steal their phone data (whether physically or remotely). Even without criminal intent, what happens when someone just loses their phone? Or accidentally drop it in the pool? Or step on it?
+
+With **everything relying on a single app and a single device**, risk is greatly amplified.
+
+Outside the user's responsibility, Orb operators and Orb stores are susceptible to various attacks. This will increase exponentially with the number of users of course, as the target becomes bigger. In fact, Orb operators have [already been hacked](https://techcrunch.com/2023/05/12/hackers-stole-passwords-of-worldcoin-orb-operators/).
+
+Then, there is the appeal of fake identities and money fraud for criminals. Already, there is a [black market](https://gizmodo.com/worldcoin-black-market-iris-data-identity-orb-1850454037) for iris data in China, where people buy iris data (or verified World ID according to World) from people in Cambodia, Kenya, and other countries for a few dollars only. The vulnerability allowing this was reportedly fixed, but it is doubtful this is the last one we hear about.
+
+The Orb itself is also an important potential attack surface. With Tools for Humanity's ambition to fill the world with Orbs everywhere, will Orbs become the next version of the sketchy ATM? Where you might wonder if this funny-looking Orb is trustworthy enough to pay your bar tab without risking emptying your crypto wallet?
+
+## Privacy legislators aren't on board
+
+Despite all its privacy promotion material, the World project has failed to convince privacy commissioners around the world of their supposedly good intentions. Perhaps in this case actions speak louder than words, and privacy commissioners aren't so gullible.
+
+With the expansion the project plans this year, we can expect even more experts will examine the company's claims and challenge its "privacy-preserving" assumptions
+
+There are many reasons to remain skeptical about these promises of privacy. Indeed, numerous countries have already suspended, fined, or called for investigation on the company's (mal)practices.
+
+### The company was fined for personal data violation
+
+In 2024, the company was [fined](https://cointelegraph.com/news/south-korea-fines-worldcoin-personal-data-violations) 1.1 billion Korean won for violating South Korea's Personal Information Protection Act (PIPA). The Worldcoin Foundation was also imposed corrective orders and recommendations. Organizations that are truly "privacy-first" rarely reach this point.
+
+The Data Custody feature, which allows (and encourages) users to share their biometric data with Tools for Humanity is now unavailable in South Korea.
+
+### Brazil has banned Worldcoin in the country
+
+In January this year, the National Data Protection Authority (ANPD) [banned](https://decrypt.co/305639/brazilian-regulator-denies-worldcoin-appeal-ban) Worldcoin's operations in Brazil, after the company's appeal was rejected.
+
+The ban comes from regulation stating that consent to process biometric data must be "free, informed, and unequivocal", which cannot be the case with the World project paying users in cryptocurrency in exchange for their iris scans. Data deletion concerns were also raised by the regulator.
+
+The World project tried again to appeal the decision, in vain.
+
+### Kenya and Indonesia suspended its operations
+
+In 2023, Kenya, one of the first country where Worldcoin was available, [suspended](https://techcrunch.com/2023/08/02/kenya-suspends-worldcoin-scans-over-security-privacy-and-financial-concerns/) Worldcoin's operations citing concerns over the "authenticity and legality" of its activities related to privacy, security, and financial services.
+
+The worse part is, months before the Office of the Data Protection Commissioner (ODPC) of the country had ordered Tools for Humanity to stop collecting personal information from its citizens. The company simply [ignored the ODPC order](https://techcrunch.com/2023/08/15/worldcoin-in-kenya/) and continued to collect biometric data from Kenyans. It only stopped after Kenya's ministry of interior and administration gave the suspension order later on.
+
+This again is quite far from the behavior of a company who genuinely values privacy.
+
+More recently on May 4th 2025, Indonesia also [suspended](https://en.antaranews.com/news/353861/indonesia-suspends-worldcoin-world-id-operations-over-public-concerns) the World project's operation in the country over concerns related to user privacy and security. The Ministry of Communication and Digital will be summoning the project's local operators to clarify the operations and determine potential violation of the Indonesia's electronic system regulation.
+
+### German regulator ordered GDPR compliance following investigation
+
+In December 2024, the German regulator, the Bavarian State Office for Data Protection Supervision (BayLDA), [issued an order](https://decrypt.co/298090/german-watchdog-cracks-down-on-worldcoin-over-biometric-data) to obligate proving deletion procedures that comply with the GDPR within one month. Additionally, the BayLDA ordered the complete deletion of certain data records that were previously collected without sufficient legal basis.
+
+Again, the World Foundation is fighting the order and will [appeal](https://cointelegraph.com/news/german-watchdog-order-worldcoin-delete-data) the decision. The company tries to argue the data collected was "anonymized", a common strategy to try evading GDPR compliance, which does not regulate anonymized data.
+
+### Data protection authorities around the world are investigating
+
+In 2023, France's data protection authority the CNIL [investigated](https://www.reuters.com/technology/worldcoin-paris-office-checked-by-french-data-watchdog-2023-08-31/) Worldcoin's activities in the country. The same year, UK's privacy watchdog started its own [inquiry](https://www.reuters.com/technology/uk-data-watchdog-make-enquiries-worldcoin-crypto-project-2023-07-25/) into the company's operations.
+
+In 2024, Hong Kong's Office of the Privacy Commissioner for Personal Data [raided](https://www.scmp.com/news/hong-kong/law-and-crime/article/3250480/hong-kong-eye-scan-cryptocurrency-scheme-probed-citys-privacy-watchdog) six Worldcoin offices citing personal information privacy and security concerns.
+
+There is no doubt more countries and regions will follow with similar investigations and bans as the World project expands to its ambition.
+
+### In the United States, the app is restricted in some states
+
+Even in the US where the company is headquartered, the app is [restricted](https://www.wired.com/story/sam-altman-orb-eyeball-scan-launch-us/) in some states. The announcement for its event this month carried a warning the World is “not available for distribution via World App to people, companies or organizations who are residents of, or are located or incorporated in the State of New York or other restricted territories.”
+
+We can also expect the project will encounter roadblocks in states that have passed [regulations specific to the collection of biometric data](https://www.huschblackwell.com/2024-state-biometric-privacy-law-tracker). This includes states like Illinois, Texas, Washington, and Colorado.
+
+### Some regions have special regulations for biometric data
+
+Around the world the number of biometric-specific regulations is growing. Even without a regulation specific to this type of data, many privacy laws have started to include special categories and requirements to govern the collection and processing of sensitive biometric data. As companies are increasingly requesting such collection, legislations to protect users are essential.
+
+For example, the province of Quebec in Canada has recently implemented [strong protections for biometric data](https://www.cai.gouv.qc.ca/protection-renseignements-personnels/sujets-et-domaines-dinteret/biometrie?%2F) with its new privacy law, the Law 25. Consent isn't sufficient to collect biometric data, as the law requires organizations to explicitly justify the necessity for such collection in the first place. Importantly, any violation of Law 25 comes with fines as hefty as the GDPR's.
+
+More privacy laws should implement such protections quickly, as corporations collecting biometric information carelessly are multiplying fast.
+
+## Welcome to full dystopia
+
+The most concerning part of the World project's recent expansion isn't its cryptocurrency grift as much as stepping out of it.
+
+If cryptocurrency enthusiasts wish to share their personal data to get into a special cryptocurrency club, they might (although privacy regulations should still protect them). But using financial coercion to get new users by exploiting vulnerable communities living in poverty is **absolutely despicable**.
+
+Further, the fact that the World project has partnered with powerful players in the financial, gaming, and even dating sectors *should terrify everyone*.
+
+Beyond cryptocurrency, if platforms start to demand users everywhere to verify they are a human and verify they are an adult through the World ID system, then **everyone will soon be subjected to this**.
+
+The amount of money invested in the project means there will be an incredible pressure to spread it everywhere soon, and *monetize* it. There will be a *strong* incentive to monetize our data and to monetize our proof of humanity. This isn't trivial.
+
+The well-known dating app Tinder has already partnered with World ID to verify the age of users in Japan. If this experiment works well, and if users comply without objection, this could be soon mandatory for *all* dating apps.
+
+Let's not stop at dating apps, the World project has already announced last week they will also be working with Razer to verify humanity of online gamers. How far can this go in the age of age verification? Will every online games with mature content soon require a World ID to play?
+
+What about social media? Tools for Humanity's team have insisted the age of AI made us incapable of detecting if we are interacting with bots online. Therefore, they must valiantly come to our rescue to verify our humanity scanning our eyeballs (which bots tragically lack). What if this human verification is expanded to all our social media accounts? Certainly, regulators pushing for authoritarian age verification online would be delighted by such a product.
+
+Then, it comes for our money. The everything app of course offers payment and money management features. This is the app where you can keep your whole wallet, containing all your official IDs, your cryptocurrencies of all kind, and even connect with your less hyped regular bank accounts.
+
+Imagine a single app, owned by a single for-profit corporation, that collects and processes all the data from all your transactions online, all your communications online, that you absolutely have to continue using for your other social media accounts, your gaming life, and your dating life.
+
+There could soon be no way to escape the grasp of World's everything app. Actually, [some governments](https://www.theregister.com/2025/05/04/sam_altman_startup_world/) (Taiwan and Malesia) have already started using it for official services, because why not.
+
+**The ways this could degenerate fast into full dystopia are infinite**, and very real.
+
+The company even plans to ship next year the Orb Mini, a pocket-size personal spy-device with which users will be able to scan their own eyeballs on the go!
+
+But why stop there? Why not scan other people's eyeballs as well? Maybe all government officials could carry one? Maybe every payment terminal could have one too?
+
+We will find out soon, in one or two years.
+
+Tools for Humanity also bragged about the numerous utilities its new technology could make possible. For example, for event tickets! Order a concert ticket with your "proof of personhood" then maybe confirm you are the owner by having your eyeballs scanned to assist to a Rage Against the Machine concert?
+
+The only fun part in this is the irony.
+
+Tools for Humanity with its expansionist dream is without a doubt hungry enough to eat the whole World™️.
+
+### A new world of wealth inequalities
+
+The company brings up a few times the mention of Universal Basic Income (UBI) in its documentation, it even mentions it briefly in its [white paper](https://whitepaper.world.org/#ubi).
+
+While puzzling, it appears Tools for Humanity might consider its cryptocurrency bribe to sign up and subsequent token giveaways as some form of UBI? Or perhaps this is only one of its other ambition to control all the financial systems in the entire world. Why UBI is even mentioned at all in this context is unclear.
+
+Regardless, it's worth mentioning a for-profit company giving cash back in exchange for biometric data isn't UBI at all, it's just a **creepy membership card points**, at best.
+
+While the World project works hard to present the idea this is a tool for the people, where everyone is equal, wealth will definitely [not be distributed evenly](https://whitepaper.world.org/#wld-token-allocation) in this new World order.
+
+Already, 11.1% of World's cryptocurrency tokens (WLD) have been distributed to the World's team, 13.6% to investors, and 0.3% are reserved for Tools for Humanity. This means these entities would share together 25% of the wealth, while 75% of the world's population (according the Tools for Humanity's ambition) would have to share 75% of what's left.
+
+In the new "human" world this corporation envisions, Tools for Humanity and its investors would own 1 quarter of the entire world's wealth. There is nothing equitable or communal in a system like this.
+
+It's important not to forget this everything app will do everything to pressure its users in eventually using Worldcoins, its ultimate goal.
+
+From Tinder's mandatory age verification to cryptocurrency financial ruin in one single move.
+
+## The normalization of surveillance
+
+Even if this process was perfectly secure and perfectly private (which it is definitely not), the problem remains the normalization of surveillance.
+
+This isn't limited to Tools for Humanity, although the way the company tries to advertise itself as a privacy-first organization makes it even more important to scrutinize.
+
+But anyone else with a similar approach to biometric data collection for verifying humanity or age or legal names should be on our radar. Moreover, if it's a for-profit corporation with the power to impose this technology on us everywhere in the world.
+
+One company should never have such power.
+
+Further, biometric data should never be used for trivial purposes like "proof of personhood" or age verification. No amount of supposedly "privacy-preserving" features can change this.
+
+The premise itself is flawed from the start to respect privacy rights.
+
+While the problem of proving identify can still be an important one to solve in *some* context, the solution to this can never be monopolized by for-profit corporations.
+
+Regardless of Tools for Humanity's intentions and efforts to convince us to trust them, any similar technology is just another step towards a global system of mass surveillance, where ultimately privacy rights and human rights are lost.
+
+So, should you scan your eyeball to get a verified World ID?
+
+**No.**
+
+**No, you really shouldn't.**

+~~I was unable to find any documentation or open GitLab issues with Tor regarding the need to take additional steps before security settings are fully applied, and~~ Tor Browser documentation does not note that a restart is required, nor does it prompt users to restart the browser after security changes are made. (update: see below)
+
+This presents a high risk to people who switch from Standard to Safer security during a browsing session with the goal to protect themselves from browser exploits.
+
+## Demonstration
+
+The effect can be easily demonstrated in your own Tor Browser install by running a JavaScript benchmark such as [JetStream 2.2](https://browserbench.org/JetStream/). These benchmarks rely on a technology called Just-in-Time (JIT) compilation to improve performance, but JIT is linked to numerous security vulnerabilities in modern web browsers. The "Safer" security level normally disables JIT entirely to prevent these issues, however, you can see virtually no performance impact when switching to the Safer security level in Tor Browser and running the benchmark again:

+  <figcaption>JetStream 2.2 benchmark results in <strong>Safer</strong> mode, <em>without</em> restarting Tor Browser</figcaption>
+</figure>
+
+While the performance is virtually identical between these two runs, *after* restarting Tor Browser and re-running the test, we see drastically lower performance results, in line with what we would expect with JIT properly disabled:
+
+<figure markdown="span">
+  ![JetStream2 benchmark results with a score of 33 and the shield indicator in the browser's toolbar indicating that Safer security level is set](../assets/images/tor-security-slider-flaw/safer-level-after-restart-jetstream2.png)
+  <figcaption>JetStream 2.2 benchmark results in <strong>Safer</strong> mode, <em>after</em> restarting Tor Browser</figcaption>
+</figure>
+
+As you can see, there is no visible indicator that anything is different between the last two runs, and there was no prompt to restart the browser after changing these settings. However, this clearly indicates that JavaScript technologies that are meant to be disabled in Safer mode can still be accessed by websites until the browser is restarted, potentially opening you up to browser exploits if you are unaware of the additional steps required to secure yourself.
+
+## Safest Mode
+
+We have not tested or verified the full extent of security features which require a browser restart. We tested whether JIT remained enabled after switching to Safer mode because it was the easiest feature to test. Safest mode disables JavaScript entirely, so the demonstration above will not demonstrate this problem exists when switching to Safest mode.
+
+However, it is possible that there are *other* features normally disabled by Safest mode which remain enabled until you restart your browser. Out of an abundance of caution, we recommend always restarting your browser after changing this setting, regardless of whether you are switching to Safer or Safest mode.
+
+## Conclusion
+
+The Tor Project advertises the security slider as a way to conveniently adjust the protections that the Tor Browser provides, but does not note additional steps necessary to ensure those settings actually go into effect.
+
+This is our public service announcement to make sure you **always completely restart Tor Browser after adjusting your security settings.** Relying on these indicators can create a false sense of security and potentially expose users relying on this security level slider to greater risk than they expect based on Tor Browser's UI and documentation.
+
+Hopefully, Tor Browser will prompt or force their users to restart the browser after adjusting these settings in a future update.

 ### Tor Browser is not the most *secure* browser
 
-Anonymity can often be at odds with security: Tor's anonymity requires every user to be identical, which creates a monoculture (the same bugs are present across all Tor Browser users). As a cybersecurity rule of thumb, monocultures are generally regarded as bad: Security through diversity (which Tor lacks) provides natural segmentation by limiting vulnerabilities to smaller groups, and is therefore usually desirable, but this diversity is also less good for anonymity.

 Additionally, Tor Browser is based on Firefox's Extended Support Release builds, which only receives patches for vulnerabilities considered *Critical* and *High* (not *Medium* and *Low*). This means that attackers could (for example):
 
 1. Look for new Critical/High vulnerabilities in Firefox nightly or beta builds, then check if they are exploitable in Tor Browser (this vulnerability period can last weeks).
 2. Chain *multiple* Medium/Low vulnerabilities together until they get the level of access they're looking for (this vulnerability period can last months or longer).

 If you think that a bridge can aid in defending against fingerprinting or other advanced network analysis more than a VPN's encrypted tunnel already can, you always have the option to use a bridge in conjunction with a VPN as well. That way you are still protected by the pluggable transport's obfuscation techniques even if an adversary gains some level of visibility into your VPN tunnel. If you decide to go this route, we recommend connecting to an obfs4 bridge behind your VPN for optimal fingerprinting protection, rather than meek or Snowflake.

[Hugging Face](https://huggingface.co/models) is a platform that lets you browse, research, and download models in common formats like [GGUF](https://huggingface.co/docs/hub/en/gguf). Companies that provide good open-weights models include big names like Mistral, Meta, Microsoft, and Google. However, there are also many community models and 'fine-tunes' available. As mentioned above, quantized models offer the best balance between model quality and performance for those using consumer-grade hardware.

+We previously recommended enabling the *Isolate Destination Address* preference in Orbot settings. While this setting can theoretically improve privacy by enforcing the use of a different circuit for each IP address you connect to, it doesn't provide a practical advantage for most applications (especially web browsing), can come with a significant performance penalty, and increases the load on the Tor network. We no longer recommend adjusting this setting from its default value unless you know you need to.[^1]

+=== "Android"
+
+    Orbot can proxy individual apps if they support SOCKS or HTTP proxying. It can also proxy all your network connections using [VpnService](https://developer.android.com/reference/android/net/VpnService) and can be used with the VPN kill switch in :gear: **Settings** → **Network & internet** → **VPN** → :gear: → **Block connections without VPN**.
+
+    Orbot is often outdated on Google Play and the Guardian Project's F-Droid repository, so consider downloading directly from the GitHub repository instead. All versions are signed using the same signature, so they should be compatible with each other.
+
+=== "iOS"
+
+    On iOS, Orbot has some limitations that could potentially cause crashes or leaks: iOS does not have an effective OS-level feature to block connections without a VPN like Android does, and iOS has an artificial memory limit for network extensions that makes it challenging to run Tor in Orbot without crashes. Currently, it is always safer to use Tor on a desktop computer compared to a mobile device.

 There are downsides to I2P's approach, however. Tor relying on dedicated exit nodes means more people in less safe environments can use it, and the relays that do exist on Tor are likely to be more performant and stable, as they generally aren't run on residential connections. Tor is also far more focused on **browser privacy** (i.e. anti-fingerprinting), with a dedicated [Tor Browser](tor.md) to make browsing activity as anonymous as possible. I2P is used via your [regular web browser](desktop-browsers.md), and while you can configure your browser to be more privacy-protecting, you probably still won't have the same browser fingerprint as other I2P users (there's no "crowd" to blend in with in that regard).
 
 Tor is likely to be more resistant to censorship, due to their robust network of bridges and varying [pluggable transports](https://tb-manual.torproject.org/circumvention). On the other hand, I2P uses directory servers for the initial connection which are varying/untrusted and run by volunteers, compared to the hard-coded/trusted ones Tor uses which are likely easier to block.

-OAuth is an authentication protocol that allows you to register for a service without sharing much information with the service provider, if any, by using an existing account you have with another service instead. Whenever you see something along the lines of "Sign in with *provider name*" on a registration form, it's typically using OAuth.
+[Open Authorization (OAuth)](https://en.wikipedia.org/wiki/OAuth) is an authentication protocol that allows you to register for a service without sharing much information with the service provider, if any, by using an existing account you have with another service instead. Whenever you see something along the lines of "Sign in with *provider name*" on a registration form, it's typically using OAuth.
 
 When you sign in with OAuth, it will open a login page with the provider you choose, and your existing account and new account will be connected. Your password won't be shared, but some basic information typically will (you can review it during the login request). This process is needed every time you want to log in to the same account.
 
 The main advantages are:
 
-- **Security**: you don't have to trust the security practices of the service you're logging into when it comes to storing your login credentials, because they are stored with the external OAuth provider, which when it comes to services like Apple and Google typically follow the best security practices, continuously audit their authentication systems, and don't store credentials inappropriately (such as in plain text).
-- **Ease of use**: multiple accounts are managed by a single login.

 ## Email Encryption Overview
 
-The standard way to add E2EE to emails between different email providers is by using OpenPGP. There are different implementations of the OpenPGP standard, the most common being [GnuPG](https://en.wikipedia.org/wiki/GNU_Privacy_Guard) and [OpenPGP.js](https://openpgpjs.org).
+The standard way to add E2EE to emails between different email providers is by using OpenPGP. There are different implementations of the OpenPGP standard, the most common being [GnuPG](../encryption.md#gnu-privacy-guard) and [OpenPGP.js](https://openpgpjs.org).
 
-There is another standard which is popular with business called [S/MIME](https://en.wikipedia.org/wiki/S/MIME), however, it requires a certificate issued from a [Certificate Authority](https://en.wikipedia.org/wiki/Certificate_authority) (not all of them issue S/MIME certificates). It has support in [Google Workplace](https://support.google.com/a/topic/9061730) and [Outlook for Web or Exchange Server 2016, 2019](https://support.office.com/article/encrypt-messages-by-using-s-mime-in-outlook-on-the-web-878c79fc-7088-4b39-966f-14512658f480).
+Even if you use OpenPGP, it does not support [forward secrecy](https://en.wikipedia.org/wiki/Forward_secrecy), which means if the private key of either you or the message recipient is ever stolen, all previous messages encrypted with it will be exposed. This is why we recommend [instant messengers](../real-time-communication.md) which implement forward secrecy over email for person-to-person communications whenever possible.

In some cases it is more usable than PGP because it has support in popular/mainstream email applications like Apple Mail, [Google Workplace](https://support.google.com/a/topic/9061730), and [Outlook](https://support.office.com/article/encrypt-messages-by-using-s-mime-in-outlook-on-the-web-878c79fc-7088-4b39-966f-14512658f480). However, S/MIME does not solve the issue of lack of forward secrecy, and isn't particularly more secure than PGP.
 
 ## What is the Web Key Directory standard?
 
-The Web Key Directory (WKD) standard allows email clients to discover the OpenPGP key for other mailboxes, even those hosted on a different provider. Email clients which support WKD will ask the recipient's server for a key based on the email address' domain name. For example, if you emailed `jonah@privacyguides.org`, your email client would ask `privacyguides.org` for Jonah's OpenPGP key, and if `privacyguides.org` has a key for that account, your message would be automatically encrypted.
+The [Web Key Directory (WKD)](https://wiki.gnupg.org/WKD) standard allows email clients to discover the OpenPGP key for other mailboxes, even those hosted on a different provider.

For example, if you emailed `jonah@privacyguides.org`, your email client would ask `privacyguides.org` for Jonah's OpenPGP key, and if `privacyguides.org` has a key for that account, your message would be automatically encrypted.
 
 In addition to the [email clients we recommend](../email-clients.md) which support WKD, some webmail providers also support WKD. Whether *your own* key is published to WKD for others to use depends on your domain configuration.

-If you use your own custom domain, you will need to configure WKD separately. If you control your domain name, you can set up WKD regardless of your email provider. One easy way to do this is to use the "[WKD as a Service](https://keys.openpgp.org/about/usage#wkd-as-a-service)" feature from keys.openpgp.org, by setting a CNAME record on the `openpgpkey` subdomain of your domain pointed to `wkd.keys.openpgp.org`, then uploading your key to [keys.openpgp.org](https://keys.openpgp.org).

 ## Email Metadata Overview
 
-Email metadata is stored in the [message header](https://en.wikipedia.org/wiki/Email#Message_header) of the email message and includes some visible headers that you may have seen such as: `To`, `From`, `Cc`, `Date`, `Subject`. There are also a number of hidden headers included by many email clients and providers that can reveal information about your account.
+Email metadata is stored in the [message header](https://en.wikipedia.org/wiki/Email#Message_header) of the email message and includes some visible headers that you may have seen such as `To`, `From`, `Cc`, `Date`, and `Subject`. There are also a number of hidden headers included by many email clients and providers that can reveal information about your account.
 
 Client software may use email metadata to show who a message is from and what time it was received. Servers may use it to determine where an email message must be sent, among [other purposes](https://en.wikipedia.org/wiki/Email#Message_header) which are not always transparent.
 
 ### Who Can View Email Metadata?
 
-Email metadata is protected from outside observers with [Opportunistic TLS](https://en.wikipedia.org/wiki/Opportunistic_TLS) protecting it from outside observers, but it is still able to be seen by your email client software (or webmail) and any servers relaying the message from you to any recipients including your email provider. Sometimes email servers will also use third-party services to protect against spam, which generally also have access to your messages.

 ### Why Can't Metadata be E2EE?
 
-Email metadata is crucial to the most basic functionality of email (where it came from, and where it has to go). E2EE was not built into the email protocols originally, instead requiring add-on software like OpenPGP. Because OpenPGP messages still have to work with traditional email providers, it cannot encrypt email metadata, only the message body itself. That means that even when using OpenPGP, outside observers can see lots of information about your messages, such as whom you're emailing, the subject lines, when you're emailing, etc.

 Peergos is primarily a web app, but you can self-host the server either as a local cache for your remote Peergos account, or as a standalone storage server which negates the need to register for a remote account and subscription. The Peergos server is a `.jar` file, which means the Java 17+ Runtime Environment ([OpenJDK download](https://azul.com/downloads)) should be installed on your machine to get it working.
 
 Running a local version of Peergos alongside a registered account on their paid, hosted service allows you to access your Peergos storage without any reliance on DNS or TLS certificate authorities, and keep a copy of your data backed up to their cloud. The user experience should be the same whether you run their desktop server or just use their hosted web interface.
 
 Peergos was [audited](https://peergos.org/posts/security-audit-2024) in November 2024 by Radically Open Security and all issues were fixed. They were previously [audited](https://cure53.de/pentest-report_peergos.pdf) by Cure53 in June 2019, and all found issues were subsequently fixed.

 Email aliasing can also act as a safeguard in case your email provider ever ceases operation. In that scenario, you can easily re-route your aliases to a new email address. In turn, however, you are placing trust in the aliasing service to continue functioning.

+
+### Over Catch-All Aliases
+
+Using a dedicated email aliasing service has a number of benefits over a catch-all alias on a custom domain:
 
 - Aliases can be turned on and off individually when you need them, preventing websites from emailing you randomly.
 - Replies are sent from the alias address, shielding your real email address.
 
-They also have a number of benefits over "temporary email" services:
+### Over Temporary Email Services
+
+Email aliasing services also have a number of benefits over "temporary email" services:
 
 - Aliases are permanent and can be turned on again if you need to receive something like a password reset.
 - Emails are sent to your trusted mailbox rather than stored by the alias provider.
 - Temporary email services typically have public mailboxes which can be accessed by anyone who knows the address, while aliases are private to you.
 
-Our email aliasing recommendations are providers that allow you to create aliases on domains they control, as well as on your own custom domain(s) for a modest yearly fee. They can also be self-hosted if you want maximum control. However, using a custom domain can have privacy-related drawbacks: If you are the only person using your custom domain, your actions can be easily tracked across websites simply by looking at the domain name in the email address and ignoring everything before the at (@) sign.

 Using an aliasing service requires trusting both your email provider and your aliasing provider with your unencrypted messages. Some providers mitigate this slightly with automatic PGP encryption[^1], which reduces the number of parties you need to trust from two to one by encrypting incoming emails before they are delivered to your final mailbox provider.

-Compared to Organic Maps, OsmAnd has more [features](https://wiki.openstreetmap.org/wiki/OsmAnd#Features) but is also more complicated to use. One noteworthy feature is the ability to overlay or underlay external map data, such as satellite images from Microsoft or [traffic data](https://web.archive.org/web/20211203063453/http://themm.net/public/osmand_traffic) from Google, although the latter is ignored by the automatic route planning. OsmAnd also has an optional integration of street view images provided by [Mapillary](https://mapillary.com).
