For only a small number of people it is sufficient for the system to find out "who the person is" meaning, the biometric data can be compared with many entries in the database to find out if this person is in the group of authorized users. If there were for example hundreds of possible users, it would be better to ask for a username then compare that biometric to only the template in the database that matches that user.
