An arrangement is provided in which an authentication key with media content and storage capabilities is configured as a removable module that interoperates with a set top box ("STB") to enable two-factor authentication to be implemented when authenticating a user to unblock media content recorded by a digital video recorder that is restricted using, for example, parental control or blocking features provided by the STB. The authentication key is also arranged with a memory to store recorded media content that is accessed from the STB which functions as an intermediary, or "proxy" device, to facilitate selecting, receiving, and recording media content from a distribution network. The authentication key is also configured with an onboard video processor that enables the authentication key to perform as a portable media player that can drive, in various illustrative examples, a built-in display device or external presentation devices such as television or monitor.
