description An electronic book distribution system includes electronic devices that reset their passcodes after specified authentication failures. The passcodes of an individual electronic device is reset to a value that is generated using a predefined function of a randomly generated support code. The support code is displayed to the user, and the user is instructed to contact a support service in order to obtain the new passcode. The support service independently authenticates the user, calculates the new device passcode using the same predefined function used by the electronic device, and provides the new passcode to the user.
