Abstract:
An authentication device includes an authentication unit configured to determine whether an input password input to a input unit matches a registered password registered in advance in a storage unit, count the number of times it is determined that the input password does not match the registered password, and stops authentication using a password if the number of times a mismatch is determined reaches a specified number, and a management unit configured to create an input error list supporting each of characters, digits, or other elements included in the registered password, on the basis of a history of errors of input to the input unit, and configured to cancel counting in a case where it is determined by the authentication unit that the input password does not match the registered password and a cause of the mismatch lies in an input error included in the input error list.
