> biometrics are usernames, they are not passwords

While I see where you're coming from, they really aren't just usernames. It's not like I can log into your e-mail account by typing VoodooJuJu and pressing Enter.

But most biometrics (at least faces and fingerprints) make terrible passwords. They can be copied and they're very hard to change if you need to.
