"Magnets won't work on steppers, and decent fingerprint scanners will ignore masks - which would make these methods useless for any well designe... oh wait."

Well actually magnets work on most kinds of motors. You essentially emulate the fields which the coils generate by sliding a magnet down the side, then turning the magnet and doing it again.

Fingerprint scanners don't ignore masks, as with any biometric method you can always fool them. Usually even very easily. (see Touch-ID)
