I haven't had a chance to test this (mostly because my USB ports are at a premium and having ANOTHER one function as a sort of key is difficult) but I have to admit this program has been in development for some time now, where a lot of similar programs have come and gone.synopsis wrote:Turn any USB flash drive to a computer lock and unlock key! USB Raptor can lock the system once a specific USB drive is removed from the computer and unlock when the drive is plugged in again to any USB port. The utility checks constantly the USB drives for the presence of a specific unlock file with encrypted content. If this specific file is found the computer stays unlocked otherwise the computer locks.

Throwing this in resources as it's unlikely to be portable.
