<p>GrapheneOS adds the option to require entering a 2nd factor PIN after
successfully authenticating with a fingerprint on the lockscreen in order to
complete unlocking the device. Since Android/iOS use biometric unlock as a
secondary unlock mechanism for convenience, this allows users to make use of a
strong passphrase as their primary unlock method with the convenience of a
fingerprint and short PIN for secondary unlock. Failure to enter the correct PIN
counts towards the standard attempt limit.</p>
