The **email clients** we recommend support both [OpenPGP](encryption.md#openpgp) and strong authentication such as [Open Authorization (OAuth)](basics/account-creation.md#sign-in-with-oauth). OAuth allows you to use [Multi-Factor Authentication](basics/multi-factor-authentication.md) to prevent account theft.

<details class="warning" markdown>
<summary>Email does not provide forward secrecy</summary>

When using end-to-end encryption (E2EE) technology like OpenPGP, email will still have [some metadata](basics/email-security.md#email-metadata-overview) that is not encrypted in the header of the email.

OpenPGP also does not support [forward secrecy](https://en.wikipedia.org/wiki/Forward_secrecy), which means if either your or the recipient's private key is ever stolen, all previous messages encrypted with it will be exposed: [How do I protect my private keys?](basics/email-security.md) Consider using a medium that provides forward secrecy:

#### 권장 설정

<div class="annotate" markdown>

We recommend changing some of these settings to make Thunderbird Desktop a little more private.

These options can be found in :material-menu: → **Settings** → **Privacy & Security**.

##### Web Content

- [ ] Uncheck  **Remember websites and links I've visited**
- [ ] Uncheck  **Accept cookies from sites** (1)

</div>

1. You may need to keep this setting checked when you're logging in to some providers such as Gmail, or via an institution’s SSO. You should uncheck it once you log in successfully.

##### Telemetry

- [ ] Uncheck  **Allow Thunderbird to send technical and interaction data to Mozilla**

#### Thunderbird-user.js (고급)

[`thunderbird-user.js`](https://github.com/HorlogeSkynet/thunderbird-user.js) is a set of configuration options that aims to disable as many of the web-browsing features within Thunderbird Desktop as possible in order to reduce attack surface and maintain privacy. Some of the changes are backported from the [Arkenfox project](desktop-browsers.md#arkenfox-advanced).
