For a whole host of reasons fingerprint reader security DOES NOT EXIST. Just forget using fingerprints. Full stop.
Passwords are the worst possible security mechanism--except for all the rest. 🙂
2FA is worthless too for a determined/skilled attacker. Love it or hate it the password is the only technique that covers all needs of security (albeit not well). Everything else is fatally flawed, usually VERY easily defeated.
Any kind of biometrics are worse than useless, because once compromised they are compromised in all places for ever more. You can't really change your fingerprints, retina pattern, etc. And all of them can be faked, either at the reader, the database side, or the comparison software itself.
