Fingerprints are NOT passwords!

The three basic rules for password security are:

  1. Never write your password down. Someone might find your note.
  2. Never use the same password for different services. Otherwise you give the operators of one service access to the other.
  3. Change your password when it gets compromised.

Fingerprints violate all of these rules. You leave them (write them down) whenever and touch a smooth surface. You only have ten fingers, so you’ll end up reusing your credentials for different services. Got a front door with a fingerprint lock and a passport? Congratulations, you just handed the keys to your home to every country, including your own, you visit. Good luck, changing them!
