Abstract: A method of authenticating a secondary communication device based on authentication of a primary mobile communication device is disclosed. Trust is established with the primary mobile communication device by a device authentication server (DAS). The DAS receives an authorization code request from a secondary application operating on the secondary communication device, and transmits an authorization code to the secondary communication device. The DAS receives the authorization code from a primary application operating on the primary mobile communication device. The DAS authorizes the secondary application based on the trust with the primary mobile communication device and the authorization code from the primary application. The DAS transmits a secondary token to the secondary application at the secondary communication device to allow initialization of a communication session from the secondary application on behalf of the primary mobile communication device.
