Methods and apparatus for providing protected content to subscribers of a managed (e.g., MSO) network via a content source accessible via an internetwork such as the Internet. In one embodiment, a user accesses a service provider portal (e.g., website), and requests content. The service provider determines whether the requesting user is permitted to access the content, and what rights or restrictions are associated with the user. This includes authenticating the user as a subscriber of the MSO, and determining the subscriber's subscription level. In another embodiment, a user's account with the MSO and service provider may be federated, thus a given user will have MSO-specific information regarding its identity (such as login information, GUID, etc.) and is able to perform a single sign on to request and receive content.
