The only thing I'm not used to is the differences between "Lock", "Logout", and "Lock With Pin". It seems more natural to me that unLocking the extension should be done via authenticator code. Logging back in is via password & authenticator, that makes sense. Lock With Pin seems to be a custom feature for a user to use a temporary PIN # during their existing browser session. But I would think that Lock (via authenticator code) could replace that.
Aside from all that, t's free and highly recommended by many long-standing tech publishers.

Excellent substitution for LastPass since they opted to make you pay for functions that were originally free. Bitwarden seems to be more functional with regards to issues I have with Lastpass.
