Methods and system for controlling access to viewable content on an individual title basis. In one embodiment, the method enables a user, such as a parent, to assign passwords to individual titles, thereby preventing unauthorized users, such as children, from viewing content corresponding to a selected title while enabling authorized users to view the content via correct entry of the password. In another embodiment, the method enables an administrative user (e.g., parent) to define allowed access levels and assign the same to various users of the system. The administrative user is also enabled to assign access levels to individual titles. In response to a user selection to view a title, the system identifies the user and determines whether the user is authorized to view the content based on the access level assigned to the title and any allowed access levels assigned to the user. The system includes set-top boxes and the like that may be used to implement the methods.
