Cockatoo vs Bitwarden

Just two optional prefixes to adapt password to each site's complexity requirements

Gestures allow to remember more with a way less effort

Available as an autonomous web-app + as an add-on for Chrome, Opera and Firefox (desktop and mobile)

Fully transparent code, which everybody can inspect thoroughly

It's based on the famous KDF "scrypt"

All passwords can be cryptographically derived from a single secret gesture (or a master-password)

Bitwarden is open source and can therefore easily be reviewed and checked for security. Its Github repository is accessible here: https://github.com/bitwarden

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

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

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

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).

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

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

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).

You can store multiple logins on the same website.

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

You could retrieve passwords in the scripts.

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

Just copy CSV text.

Save data on the web.

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

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.
