Abstract: A system and method for personalizing a TV gateway is disclosed. Specifically, the disclosed system includes a TV gateway authentication infrastructure and a user authentication infrastructure in communication with external networks. The TV gateway authentication infrastructure accesses the external networks and authenticates the TV gateway. The user authentication infrastructure authenticates an end-user via end-user credentials contained in a personal tamper resistant device, which is in communication with the TV gateway. When an end-user is authenticated, an end-user profile containing TV service credentials is loaded on the TV gateway enabling the fruition of authorized end-user TV content on a TV display.
