Abstract
Systems and methods of rotating content license management for multiple terminals associated with the same content service subscription user account are disclosed. An ephemeral master device (EMD) is selected from a domain of client devices associated with the same user account. The content service generates an Ephemeral Personal Credential (EPC) associated with the user account, which is temporary and is updated periodically or randomly. The EMD role rotates among the devices in the domain periodically or randomly. The updated EPC is sent to the current EMD. A client device can access content via the user account by providing 1) the account credentials and 2) a valid EPC. Account credentials may be shared with the client device. The EPC is shared with the client device when the client device moves within a particular range of the EMD (or another device in the domain which has the EPC) to synchronize the EPC.
