How to Use PenDrive or USB Flash Drive to Lock PC
admin | Jan 04, 2010 | Comments 1
If you want to prevent unauthorized access to your computer at workplace or home, we usually use password to protect it. Every time we log off we need to close all session and to logon we need to annoying reenter passwords.
Ever want to lock your computer in a convenient and secure way using Pendrive or USB flash drive? You can try a free tool called Predator.
Predator locks your PC when you are away even if your Windows session is still opened. It uses just a regular Pendrive or USB flash drive as an access control device.
It helps you to lock the current windows session easily just by unplugging your USB flash drive. Once it is removed, the keyboard and mouse are disabled and the screen darkens.
When we reinsert our Pendrive or USB flash drive the keyboard and mouse are immediately released with the display is restored. Life never been easier and fun lol.
Predator installation steps
- Type new password in the New Password field. (You will use it to unlock your session if you lose your USB key)
- You must enter at least 6 characters, letters, figures or signs. The password is case sensitive (uppercase and lowercase letters are different).
- Check that the drive letter displayed under USB key drive actually matches your flash drive or choose the correct letter from the dropdown list.
- Click the Create key button
- Finally, click Ok
Please be advice that PREDATOR free edition is for private, non-commercial use only.
