In this personal authentication system, when an authentication server 3 has received a login request for a particular service from a terminal device 1, the authentication server 3 generates a service code associated with the particular service, and transmits the service code to the terminal device 1. Upon receiving this service code, the terminal device 1 outputs the service code in a predetermined format. A user authentication device 4 receives the service code output from the terminal device 1 and transmits the received service code to the authentication server 3. Then if the authentication server 3 succeeds in authenticating the user authentication device 4, which has transmitted the service code to the authentication server 3, then the authentication server 3 permits the user associated with the user authentication device 4 to log in for the particular service. |
