Welcome to ZeroKeyUSB

This section walks you through the device screen by screen, with illustrations and the buttons you need to press at each step. No prior technical knowledge required — just the device and a USB-C cable. ZeroKeyUSB device overview

​
The five buttons

Everything is controlled with five golden touch pads arranged in a cross on the right of the screen: Throughout these guides you will see the button highlighted in cyan on the illustrations. That indicates the button to press to move to the next step.

Before you start

1

Plug in the USB-C cable

Plug ZeroKeyUSB into any USB-C port on your computer, tablet, or phone. The device draws about 20 mA — less than a wireless mouse — and needs no battery.
2

Check the orientation

If the golden dots end up on your left instead of on the right, simply flip the device. During the initial tutorial you can also rotate the screen in software.
3

Choose your PIN

Before starting the initial tutorial it helps to have a 4–16 digit PIN in mind. If you forget it, there is no recovery — only wiping and starting over.
