USB Raptor can lock the system once a particular USB drive is removed from the computer and unlock when the drive is plugged in again to any USB port.

The utility continuously checks the USB drives for the presence of a specific unlock file with encrypted content. If this particular file is found, the computer stays unlocked; otherwise, the computer locks.

To release the system lock user must plug the USB with the file in any USB port.

Alternatively, the user can enable (or disable) two additional ways to unlock the system, such as a network messaging or password.
