A system and method for enhancing passwords, access codes, and personal identification numbers by making them pace, rhythm, or tempo sensitive. The sequence of characters comprising the password/access code/personal identification number has an associated timing element. To access a restricted device or function a user must enter the correct character sequence according to the correct pace, rhythm, or tempo. The entered sequence and timing element are compared with stored values and access is granted only if the entered and stored values match. In an alternative embodiment the stored timing element is set, and periodically altered, by a computer or program without consent from the user and visual, auditory, and/or tactile prompts indicate the correct timing element to the user during the authentication process.
