A one-key USB keyboard
Riddle me this; What is the worlds smallest keyboard, with only one key, which gives you a different result every time you press it? It’s Yubikey from Yubico. Yubikey is an authentication token, which acts as a USB keyboard. You can use the Yubikey to output a one-time password to a password field of a system which supports this.
Check it out, it’s cool.
