About
USB Lock is a small application for locking/unlocking the screen using any USB flash drive, with two-factor authentication. Two-factor authentication requires the use of two authentication factors. These two factors are something the user knows and something the user has. For example, USB devices and password.
Features:
The screen goes black or displays the selected image when locked, and when you press a key or click the mouse, a text box appears with an optional password.
Use a global hotkey to lock your screen.
Does not go into sleep mode or terminate running applications. Leave applications running while the system is protected.
Use with a password for two-factor authentication.
