Yes. Any biometric reading, such as a fingerprint, retina scan or DNA sample portrays authentication based upon something the user is.
You cannot portray identification upon something unknown. It must be something known only to the user, or be something the user is (such as a fingerprint, retina scan or DNA sample) or something the user has (such as an ID card).

1. Fingerprint.
No. A biometric identification, such as fingerprint, retina scan or DNA sample portrays something that the user is.Authentication is achieved in one of three ways:something the user is (a biometric reading)something a user has (such as an ID card)or something the user knows (such as a PIN)For improved security, the user may be required to present two such authentications, such as an ID card and PIN. Or, preferably, all three, such as an ID card, PIN and retina scan.
Not always. Authentication is based upon one or more of the following:Something the user knows (such as a PIN).Something the user has (such as an ID card).Something the user is (such as a fingerprint).
