@funky Welcome to the forum!
Yes, the Free version of Bitwarden supports the use of modern Yubikeys (e.g., Series 5 or Security Key series or Bio Series) for 2FA by FIDO2/WebAuthn, but if you wish to use the (now practically deprecated) Yubico OTP feature, then you have to upgrade to Premium.
However, you should beware that if you want to use the “Desktop App” version of Bitwarden (which is optional — most people use the browser extension and/or one of the mobile apps), then FIDO2/WebAuthn is only supported on Windows (not on macOS or Linux).
As mentioned above, Free accounts can use FIDO2/WebAuthn for 2FA, and also supports the use of TOTP authenticator apps or 2FA by email.
Last time I checked, it was the only free password manager that offered automatic cloud syncing of an unlimited number of passwords for an unlimited number of devices, supporting devices across different platforms (iOS, Android, macOS, Windows, and Linux). Other differentiators compared to some of the alternatives include the fact that Bitwarden is completely open-source, meaning that you have the ability to know exactly what Bitwarden does with your passwords, and experts have the ability to independently verify that Bitwarden’s code is secure. In addition, being an open-source project allows community members (Bitwarden users) with programming experience to contribute code for new features that they would like to have.
The Bitwarden subreddit gets this type of question periodically, so you might find some helpful discussions there.
I think so, but YMMV. If you’ve previously used a different password manager, you will probably have an initial period of adjustment during which you may be confused/annoyed because Bitwarden doesn’t do things the same way you were used to in your previous password manager.
Yes.
