Abstract
There is proposed a user authentication method that uses a time-based password (TP) having a relatively long update cycle instead of a TOTP having a conventional short update cycle (e.g., 60 seconds). The present invention is a user authentication method executed by an authentication system that performs authentication of a user who performs access from an information communication terminal device in order to use a usage target system by using a reference terminal device that includes a security token capable of generating a TP. The authentication method includes setting an update cycle of the TP to a first update cycle of 30 days, 1 month, or a time period longer than 1 month, receiving a user authentication request that includes a time-based password generated by the security token according to the set first update cycle, and performing the authentication based on the TP contained in the received user authentication request.
