Alternative the user can enable (or disable) two additional ways to unlock the system such is network messaging or password. To release the system lock user must plug the USB with the file in any USB port. If this specific file is found the computer stays unlocked otherwise the computer locks. The utility checks constantly the USB drives for the presence of a specific unlock file with encrypted content.

Note: It is important that the power supply is connected to the Raspberry Pi and the keyboard is connected to the Raspberry Pi.
