Lock user screen every time the flash drive is unplugged, creating a second factor authentication on the machine
Every time you start the application, it initiates a process that is constantly verifying if the USB device is connected to the computer.
If the device could not be found, the program sends a message to the system in order to lock the screen. This way, you can only use the computer if you have the password and the flash drive
- Flash drive
- Computer running Windows or Linux (tested on Windows 7 and Arch Linux. Others distributions should work like charm)
- Python 2 or 3 interpreter (Windows users can compile the application using py2exe)
- Edit the source in order to change the variables values
Only change the device name from flashDisk = "CHANGE_ME" to whatever is your device serial number

wmic logicaldisk get volumename
