Bitwarden vs FairEmail

Bitwarden is open source and can therefore easily be reviewed and checked for security. Its Github repository is accessible here.

It is easy to start as the majority of features are on the free version.

Automatically synchronises across various devices and platforms. Passwords get fully encrypted locally before leaving the computer.

No ads, no tracking.

There are plugins for Firefox, Chrome, Safari, Opera, Edge, Vivaldi and Tor Browser.

No need to think of individual passwords. This can be easily accomplished with an easy to use built-in password manager.

End-to-end AES-256 bit encryption, salted hashing, and PBKDF2 SHA-256.

Offers 2FA with Authy, Google Authenticator or via email.
Additionally, the Pro Version has Duo Security with Duo Push, SMS, phone call, and U2F security keys: YubiKey (any 4 series device or YubiKey NEO) and FIDO U2F (any FIDO U2F certified key).

Possibility to manage passwords without installing the app or the browser plugin.

You can store multiple logins on the same website.

Very easy to add personal notes.

You could retrieve passwords in the scripts.

When a site has multiple credentials (like I have for some brokers and banks), then the most recently used is automatically populated (if auto-fill is opted). This feature is unique (to my knowledge) and spectacular (especially for sites that log you off frequently and re-logging in is required).

Android app is a little slow and buggy, but it works well and has been improving.

Host your own server via Docker for small installations or by package for multiple servers.

The features included in the free version are totally sufficient for most personal uses. No limitation of devices synching.

You can use Windows Hello or Apple's TouchID on PC to unlock desktop applications and browser extention.

Folders can be created within folders.

It can also be used for sites where the domain changes frequently.

Just copy CSV text.

Save data on the web.

Using enterprise subscribtions you can share password entries among your colleagues via 'collections' or with other companies that are connected to yours. You decide if it's your personal entry or a companies.

Auto-fill by specifying the form with the selector of css.

Multiple identities per account, notifications per account or contact.

It is actively maintained. The used libraries are up to date and bugs are fixed quickly.

There are no trackers within the app and trackers sent with mails are disabled by default. This app lets you read and compose emails with your privacy in your very own hands.

Privacy features are excellent.

~ 20 MB.

Supports both OpenPGP and S/MIME encryption for total privacy.

Allows to configure maximum size of email downloaded immediately.

Some HTML mails may show different links and link texts, this app however will show you the real link before opening, protecting against phishing and scams

Some domain names may use non-ASCII characters looking similar to the latin alphabet (e.g. some cyrillic characters). This app will show you the punycode representation of the domain, if that is the case and thus protect you against phishing and scams.

Some HTML mails may include ressources that can track you. This app doesn't load them by default, but reformats the text, increasing both privacy and readability.

There are open standards for any email provider to show how an email client should connect to the server. This app supports both RFC 6186 as well as Thunderbird Autoconfiguration standards.

Supports authenticating with the mail server using OAuth, thus increasing security.
