Bitwarden vs Element (formerly Riot)

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.

You're not confined within Element's or even Matrix garden, and you don't have to make users of other networks switch to Matrix.

Code snippets in chats can be highlighted with Markdown.

Element has a very simple interface, adding the ability for more inexperienced users to use it.

Element allows for fully encrypted text, voice, and video chatting.

Want to watch that flick at YouTube and discuss it at the same time? Have Grafana graphs stacked above your DevOps team chat? Collaboratively edit Google Docs and chat over without switching applications? This is possible with Element.

An open network for secure, decentralized communication.

Search messages in your current room, or all the rooms you're in. Not subject to a message history limit like Slack.
