Identification and authentication are the same in this context. You're not identified by a username until you give your password. Anybody can just wave around a username, but you're not identified (authenticated) until you have the password. Similarly, the biometrics won't identify you if people can easily fake them.

And from your sources:
identification (the act of designating or identifying something)
authentication: The process of identifying an individual

Looks pretty similar
