System and methods for password protecting an attribute of content transmitted over a network. Content such as a text file, an audio file, a video file, and the like, sent over a network is protected by a password. A sender setting up the protection may determine which attribute of the content is to be protected by the password. Attributes that may be protected include time to access, number of accesses, permission to forward, permission to store, and the like. In a time to view example, the received content may self-destruct unless the receiver enters the password within a specified time period. Protection may be set up such that every time the receiver attempts to access the content, the password has to be re-entered. Access by an unauthorized user who may have possession of the computing device with the received content is prevented by content level protection.
