Isn't a password also a form of identification? The idea is that only _you_ know what to type, much the same as only you have those fingerprints (otherwise it'd be pointless). I think maybe we shouldn't look at it as much in terms of what it is -- a fingerprint, or a string of characters -- but the role it fulfills: unlocking something. We just can't extract your password from your brain or it'd probably be treated the same as a fingerprint... right?

You're hitting at the difference between identification and authentication. We use tokens/passwords/etc for authentication of a public ID. I feel like one's fingerprint is pretty commonly used as an identifier, so using it for a password (heck, engineering it into your system in the first place) is terrible.
