Fingerprints aren't changeable and they're not really secrets. Security fail. They are good for things like tracking convicts or parolees or DRM shackled users which are usage scenario were you don't want people to be able to change their identifier but that's about it. Also there's no distinction between the identity and a password. It's the same mistake made with SSNs.
