## Abstract

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.

## Claims

### Claim 1

An apparatus for creating and storing computer passwords, the apparatus comprising an array of M wheels arranged longitudinally on a central spindle, wherein each of the wheels has a plurality of segments and is labeled with a selection of N characters, such that when one or more of the wheels are rotated to create a longitudinal line of characters across one of the plurality of segments of the wheels as a master password known to the user, then N−1 additional, unique password pairs, originally unknown to the user are created along parallel lines of remaining segments of the plurality of segments of the wheels and which, if the wheels are then misaligned for obfuscation of the master password and resultant passwords when not in use, can be realigned by means of reestablishing the master password to recreate the N−1 unique password pairs, wherein the central spindle is equipped with M sets of a spring and ball located in channels, such that each ball engages detents in a corresponding one of the M wheels, there being N detents, to provide alignment of the wheels and the characters thereon longitudinally, together with an audible signal of proper alignment;
wherein the array of M wheels is held in contact with one another by means of endcaps affixed on opposite ends of the center spindle, contacting outer wheels of the array of M wheels;
wherein the endcaps are fitted with indentations or other designated locations for labeling or other unique marks that are longitudinally aligned to the positions established by the detent and spring and ball arrangement, allowing for designation of a created password for a specific account, computer application, or other purpose, and wherein the indentations or other locations for labeling and marking incorporate one instance on either endcap for opposing alignment arrows or similar indications to designate the position of the master password and thereby provide regularity in the alignment of created passwords to the labeling or marking.

### Claim 2 (depends on 1)

The apparatus of claim 1, wherein the characters are selected from upper and lower-case letters, numbers, and special characters found on standard computer keyboards.

### Claim 3 (depends on 1)

The apparatus of claim 1, wherein the labeling of the wheels incorporates P unique colors on each character as a background to some or all of each of the N characters, thereby providing a further means for creating the master password in addition to use of the characters on the wheel.

### Claim 4 (depends on 1)

The apparatus of claim 1, wherein each wheel is fitted with a grip to facilitate rotation.

### Claim 5 (depends on 1)

The apparatus of claim 1, where one of the endcaps is fitted with a bracket that allows the apparatus to be affixed to a chain or similar securing means to prevent accidental loss.
