ABSTRACT:
An information processing apparatus is disclosed that uses a function of an external apparatus using certificate information from an authentication apparatus for authenticating a user. The information processing apparatus includes: a receiving unit that receives authentication information for causing the authentication apparatus to authenticate the user; a first acquiring unit that acquires first certification information indicating that the user has been authenticated by sending the authentication information to the authentication apparatus; and a second acquiring unit that acquires second certification information for using a function of the external apparatus from the authentication apparatus based on the first certification information. It is possible to provide an information processing apparatus that, even if a certificate for using a service expires, can continue using the service without having the user notice the expiration.
