Relay device, relay method, and non-transitory computer readable medium

A relay device includes an identification information acquisition unit, a privilege information acquisition unit, a memory, and a controller. The identification information acquisition unit acquires user identification information for allowing the relay device to identify a user. The privilege information acquisition unit acquires privilege information indicating that access to the service providing device is authorized from a service providing device which provides a service to a client device used by the user. The memory stores the user identification information and the privilege information in association with each other. Upon receiving a service processing request made to the service providing device and transmitted together with the user identification information from the client device, the controller controls the service providing device to perform communication processing corresponding to the service processing request using the privilege information stored in association with the user identification information.
