A login controller 130 has a function of allowing a user to log in to an information processing apparatus 10. A sign-in controller 140 has a function of allowing the user to sign in to a network service provided by a server. At login time, a login information receiving unit 132 receives a pass code input by the user for login authentication. A login processing unit 134 performs login authentication using the received pass code. If it is determined that the pass code received by the login processing unit 134 is incorrect, a sign-in processing unit 144 causes the user to sign out of the network service. When the user again signs in to the network service, a screen generating unit 120 receives the pass code for login authentication. A registration processing section 110 then registers the received pass code in a registered user information holding section 150 as a new pass code. |
