You might have seen this in a Hollywood movies, A CIA guy flicks in a USB pen drive into a computer and it starts giving out data. How would like a similar setup on your own PC or laptop? Remember, using a login password is easily hackable. But having a USB lock not only gives that bit of extra security to your computer but adds a pro hacker like touch. Not only does it look cool, and high tech (in a way), it’s also rather practical to have a USB flash drive for locking or unlocking your PC.

For using your day to day USB pen drive as a lock, there are various third party software. For that, you don’t need to type in a password all the time; you can set a really strong password, and then not need to really remember it, because you can simply unlock your PC or Mac with a USB drive, adding a very strong layer of security to your system. So, if you’re wondering how to do the same on your home PC, here is a set up guide to Lock Unlock PC with USB Drive:

1. Lock Unlock PC with USB Drive Using Predator

Predator, a free Windows program, turns your USB drive into a key that locks your computer when it’s removed. To unlock your computer, you’ll have to plug the USB drive back in. If somebody else attempts to access your computer without the USB flash drive, he/she will get a Hollywood-style  “Access Denied” message.

Step 1: Firstly, you have to download the Predator software. (software are different for both 32 bits and 64 bits, make sure you are using the correct version).

Step 2: Once Predator is downloaded, launch it and plug in your pen drive. When you insert the drive, a dialog box will appear asking you to create a password. Click OK to continue.

NOTE: None of the contents of the drive will be deleted or altered in any way, so feel free to use your primary thumb drive.

Step 4: In the last step, Predator will exit. When it does, click the Predator icon in the taskbar to restart the program. A few seconds later, the icon will turn green, alerting you that Predator is running. For every 30 seconds, Predator will check to see that your USB drive is plugged in. If it isn’t, your computer will dim and lock down.
