An authenticating apparatus that authenticates whether a user is a registrant based on biometric information includes a biometric information input unit to input the biometric information, a registered information memory unit to memorize, together with a single or plural registrants of the biometric information, registered biometric information for each of the registrants, an identification candidate information memory unit to memorize candidate information representing registrants selected from the registrants of the registered information memory unit, and an identifying unit to compare the biometric information of the user input to the biometric information input unit and the registered biometric information of the registered information memory unit to decide on a single registrant or select plural registrants based on similarity, and, when plural registrants are selected, memorize the plural registrants in the identification candidate information memory unit as candidate information to use the candidate information as objects to be identified for biometric information of a subsequent input.
