This is a hardware password manager, built with PIC18F2455. Computer sees it as a standard USB HID keyboard, so it works on every computer and needs no extra software. When you are asked to type the password, you just plug it in USB port and press the corresponding key. 

So... 
...no manual password typing... 
...no driver installation... 
...no password keeping in the computer... 
...no crackable PRNG password creation... 
...no peeking over your shoulder while you type the password... 

Dimensions are 76x24x12 mm, which is not bigger than most USB sticks. It uses the internal white noise TRNG to generate your passwords, which are held in internal MCU flash.
