Kryptonite generates and stores an SSH key pair on a mobile phone. The Kryptonite app is paired with one or more workstations by scanning a QR code presented in the terminal. When using SSH from a paired workstation, the workstation requests a private key signature from the phone. The user then receives a notification and chooses whether to allow the SSH login.

For more information, check out krypt.co.
