A system and method for user authentication employing a portable handheld electronic device to store, in digital form, a user's password, access code, or PIN. The portable handheld electronic device can be any such device capable of visual output and/or auditory output, such as a mobile telephone, a personal music player, or a PDA. When the user receives a true visual cue and/or a true auditory cue from the portable handheld electronic device, an input command can be entered that will cause the password, access code, or PIN to be transmitted to gain access. In an alternative embodiment, the password, access code, or PIN is changed during each access granted session and stored in the portable handheld electronic device. A new security code is therefore used each time the user seeks access.
