Nossa lista de recomendações contém clientes de e-mail que suportam tanto [OpenPGP](/encryption/#openpgp) e autenticação forte como [Open Authorization (OAuth)](https://en.wikipedia.org/wiki/OAuth). OAuth permite-lhe utilizar [Multi-Factor Authentication](/multi-factor-authentication) e prevenir o roubo de contas.
Recomendamos armazenar uma chave de recuperação local em um local seguro, em vez de utilizar a recuperação do iCloud FileVault. warning "Email does not provide forward secrecy"
When using end-to-end encryption (E2EE) technology like OpenPGP, email will still have [some metadata](email.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:

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