Abstract: In a management system, an apparatus that is present in a user environment obtains a code that is specific to a device containing a consumable agent to be consumed for image formation or specific to a cartridge-type device insertable into an image-forming apparatus. A server apparatus that is present in a remote environment performs authentication for the device based on the code obtained by the apparatus. When the authentication performed by the server apparatus is successful, a replenishment path of the consumable agent from the device to the image-forming apparatus is opened or the replenishment path is allowed to be opened, or an inhibiting mechanism capable of inhibiting the device from being inserted into the image-forming apparatus is put in a state in which the device can be inserted.
