PROBLEM TO BE SOLVED: To provide a terminal authentication system or the like for reducing the burden on a user at PSK authentication. SOLUTION: In a terminal authentication process in the terminal authentication system 1, a terminal 5 generates an authentication code by using shared-key information that is pre-shared with a particular authentication server 3 requested to authenticate the terminal 5 itself and that is retained by the terminal 5 itself; the terminal 5 then transmits the URL of the particular authentication server 3 requested to authenticate the terminal 5 and the authentication code to an access point 7; the access point 7 in turn generates authentication request information and transmits the generated authentication request information to the authentication server 3 related to the URL received from the terminal 5; based on the authentication request information received from the access point 7, the authentication server 3 identifies the shared-key information that the authentication server 3 itself retains, and verifies the authentication code using the shared-key information identified.
