A fingerprint authentication apparatus stores fingerprint data of plural fingers. The fingerprint authentication apparatus stores a history of a result of an authentication process executed using the fingerprint data. The fingerprint authentication apparatus determines the number of accepted fingers, which is the number of fingers from which the fingerprint data is accepted from a user during the authentication process, and a false acceptance rate based upon the history. The fingerprint authentication apparatus accepts the fingerprint data from the fingers in the determined number of accepted fingers. The fingerprint authentication apparatus collates whether each of the accepted fingerprint data coincides or not using the determined false acceptance rate. The fingerprint authentication apparatus authenticates a user based upon a collation result.
