The methods include maintaining a library of digital content identified with the user account for access by the at least one wireless mobile device, and initiating streaming of the digital video content to the at least one wireless mobile device without requiring user authentication from the at least one wireless mobile device, based on the registering of the telephone number as the pre-authorized identifier. An apparatus for performing the method comprises a processor coupled to a memory, the memory holding instructions for performing steps of the method as summarized above.
