1. An authentication device comprising:
at least one memory configured to store instructions; and
at least one processor configured to execute the instructions to:
acquire first position information indicating a change in a position of a user's first earphone executing a first authentication based on otoacoustic authentication;
estimate motion of the user wearing the first earphone based on motion information indicating the motion of the user, the motion information being generated based on the acquired first position information;
execute authentication of the user in a terminal connected to the first earphone based on the authentication result by otoacoustic authentication and the motion information;
output earphone operation instruction information instructing the user to change a position of a second earphone used in the other ear of the user;
acquire second position information indicating a change in the position of the second earphone; and
estimate whether the authentication result by the first authentication for the user is correct or not based on the earphone operation instruction information and the second position information.
