Ways in which fingerprints are different from passwords:
- Your passwords can be kept secret. You leave your fingerprints lying around everywhere.
- You should have different passwords for everything you do. You only have ten fingerprints to choose from (if you have the typical allocation of hands).
- If the worst happens, you can always change your passwords. You can't change your fingerprints. You're stuck with them for life.
- You can forget your passwords. You always have your fingerprints on you.
- Your fingerprints aren't easily guessable, as you never have one that's the name of your favourite football team or something dumb like Fingerprint1.
Ways in which fingerprints are the same as passwords:
- You have to trust that the organisations with whom you share your fingerprints and passwords take security seriously.
