I was gonna ask about the biometrics part in a separate question, but its both about security, so might as well combine it in one post.
Okay so I don’t use password managers. I just try to make easy to remember passwords 3-4 random words + 3-4 random numbers. Online accounts can’t be brute forced anyways. Edit: I mean most websites have log in limits don’t they? Maybe I’ve been mistaken?
For offline accounts, I just increase the words and numbers. For mobile I don’t use biometrics, although I’ve been testing whether or not I want a pin + no biometrics or alphanumeric password + biometrics. I just can’t decide.
Basically, they enable you to have a different, randomly generated and very long password for each service with minimal impact to your usability.
Personally I use keepassxc with the accompanying browser addon. When I unlock my PC and need a password, I have to enter my master passwort to unlock the database. Afterwards, until I lock my PC again or manually lock the database, I can click on a single button in my browser window to automatically fill out my login information. I do not know any of my passwords beside the master passwort.
I have yet to need the forget password option after switching to a password manager since I can always look up my passwords.
