A communication system includes a client apparatus and a relay apparatus. The client apparatus includes an acquisition unit and a request unit. The acquisition unit acquires permission information indicating permission to access a service provider apparatus, from the service provider apparatus. The request unit transmits the permission information and user identification information which has been input, to the relay apparatus so as to request access to the service provider apparatus. The relay apparatus includes a storage controller and an access unit. The storage controller stores the permission information and the user identification information which are received from the client apparatus, in a storage unit in such a manner that the permission information and the user identification information are associated with each other. The access unit accesses the service provider apparatus by using the permission information stored in the storage unit. |
