Developed by mathematical scientists, this device aims to be a password generator like no other. Because it is not electronic, it is unhackable, and because the user can twist it like a traditional Rubik’s Cube, it is even more random than most other password generators. Additionally, each device gets its own set of characters created by cutting-edge random number generator technology, meaning that no two cubes will be the same even before you twist them.

“Our device is more sophisticated than any hardware device that we have seen,” Dr. Petrus Potgieter, one of the cube’s creators, told Digital Trends. “The Ultra Password Cube is the ideal way to generate passwords that are virtually immune to online ‘dictionary’ attacks.”

A crowdfunding campaign for the device is currently live on Kickstarter. More information and instructions on how to use the device are included in the video below.
