Systems and methods for authorizing operations associated with blocked media assets using two-factor authentication. In some aspects, a media guidance application (e.g., executed by a set-top box or other user equipment used to store and display media assets) prompts a user for a password (e.g., a personal information number) in order to unlock the content for viewing.
