 When you open Onion Browser for the first time you're given the option to connect to Tor via [Orbot](https://www.privacyguides.org/en/tor/#orbot), or with a built-in Tor network proxy. Using the built-in option is the easiest, it connects very quickly and doesn't require a separate app. It also allows you to [use Tor alongside another VPN app](https://www.privacyguides.org/en/advanced/tor-overview/#safely-connecting-to-tor), which may be helpful in certain circumstances. The Orbot app acts as its own "VPN connection" in iOS preventing the possibility of combining it with another VPN, but it is more flexible and it extends Tor network protections to every app on your device.

 I confirmed the built-in option works perfectly fine, in fact I occasionally had trouble connecting Orbot to Onion Browser, where it would re-prompt me to start Orbot even though it was already running until I restarted the Onion Browser app. The built-in proxy generally worked seamlessly. However, for most people using Onion Browser alongside Orbot probably still makes more sense. It's the official recommendation from Tor Project and the browser's developer themselves, so that's what I'll be sticking with for the rest of this review.

 There are three configurable security levels in Onion Browser: Bronze, Silver (the default), and Gold. These levels roughly correlate to the *Safe, Safer, Safest* [security levels](https://tb-manual.torproject.org/security-settings/) in regular Tor Browser.

 Because Onion Browser is built on Apple's WebKit, these security improvements extend to Onion Browser as well. Most notably, external web fonts *are* blocked in Onion Browser with Lockdown Mode enabled, just as they are in Safari. These are disabled in desktop Tor Browser's Safest mode due to both privacy concerns, and security concerns related to the font rendering engine on your device, so having the option to disable them here on iOS is very useful for those looking to maximize their security.
