An apparatus made of wheels arranged axially on a central spindle that are rotated with respect to one another in myriad combinations to create unique, complex passwords for use in computer systems. The wheels are labeled with a randomized selection of characters found on standard computer keyboards, including upper and lower-case characters, numbers, and special characters, together with some or all characters put on colored backgrounds found on each wheel. A memorized master password is used to align the wheels, which reveals a series of unique, complex passwords arrayed across the perimeter of the wheels for use in computer applications. When not in use, the wheels are rotated to a random or storage position, providing for obfuscation of the passwords and allowing the device to be stored in plain sight.
