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. 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.
KeePass, synced to my VPS. The key file on exists on my phone+tablet+laptops. Its biometrically authenticated on the phone+tablet - unfortunately, its just password-protected on the Debian laptop. The VPS is automatically backed-up to a completely different cloud service every other night. In the case of catastrophe on the VPS, there’d be cached copies of the vault on my devices and I can fairly easily retrieve a timestamped copy from the cloud server.
I also use a 2FA autheticator app on the phone+tablet. Its similarly biomentrically authenticated and backed-up to the VPS/Cloud.
