Abstract
In one example, a device directory server may maintain a digital rights management list for a user device belonging to a device group associated with a user. The device directory server may maintain a primary digital rights management list associating a user device with a primary online account for a user having a content license for a digital content item. The device director server may receive a status update indicating the user device is still in use by the user if sent by the user device. The device directory server may determine whether a status update has been received from the user device. The device directory server may deactivate the user device on the primary digital rights management list when no status update has been received within a pruning period for the user device to be associated with the primary online account.
