@Dan_Cote Hi!
You can’t register for a Bitwarden account without entering a master password, so you unfortunately forgot yours. (PS: unless you are part of an Enterprise organization)
And that is not good news for you, I must say.
Please read the following two threads carefully, as they are more or less the same situation you have now - and all good advice is already there:
- Forget master password but have access to vault through chrome extention
- Change password without knowing the Master one
PS:
Technically, you can’t login to your vault via biometrics - you can only unlock your vault via biometrics. As you can read in the two threads: don’t log out on your Bitwarden app(s) now! Stay logged in, as you possibly have to export your vault, and possibly manually. You won’t be able to login again if you logged out now, as a login requires the master password (as long as you don’t have set up “login with device” or a “login with passkey”-passkey)…
