In a case where a standard authentication system is being connected to an image forming device, a cooperation processing unit of the image forming device uses a set value managed by a set value management unit thereby to cooperate with the standard authentication system. In a case where an extension authentication system is being connected to the image forming device, the cooperation processing unit of the image forming device uses a set value managed by a set value management service, which is an extension service that provides a function other than a standard function of the electronic device, thereby to cooperate with the extension authentication system. A program for the cooperation processing unit and a program for the set value management unit are included in firmware of the image forming device. A set value management program for the set value management service is not included in the firmware.
