Lock and unlock your screen with a usb storage device.

Screen turns black or displays selected image when locked and optional password text box appears when key pressed or mouse clicked.

Use global hot key to lock the screen.

Does not sleep or shutdown running applications. Leave applications running while the system is protected.

Use with a password for Two-Factor authentication.

Two-factor authentication requires the use of two authentication factors. The two factors are something the user knows and something the user has. For example a USB device and a password.

Coming Soon: 
Idle timer to lock the screen when system inactive.


Release Notes:

multiple screen support

Nice - Turns my old USB stick into a key. I'd like to see a few more features. It would be nice if it could stop my music when i yank out the disk.

Second Monitor - This app only blocks one screen. If you have a second monitor, you can access the entire computer. It is better to lock your computer using the OS.

Fails - Will not even lock the screen in 10.13.6. Really thought it would lock the computer. But it does no such thing. Do not waste your moeney on this. Locking the screen is not security. Simply force quite and restart to get where you were without the USB stick.

Not Secure - The password on usb is only 37 characters long. Plus there isn’t very many customization options
