1. An authentication device comprising:
a memory configured to store combination information including:
(i) a plurality of combinations of biometric information identifying one or more registered users, and identification information identifying one or more terminals carried by the one or more registered users, and
(ii) a number of successes in user authentication for each combination; and
a processor programmed to:
acquire biometric information and identification information on each of the users;
authenticate the user based on (i) a result of a comparison between the combination information and the acquired biometric information and identification information of the users and (ii) a threshold for determination of success or failure in user authentication of the user; and
in response to a condition being satisfied that a number of successful authentications of the user exceeds a predetermined number, set the threshold such that a false acceptance rate for erroneously authenticating a person other than the user is lower than when the condition is not satisfied.
