How to lock and unlock a Windows computer using a USB device for free

Security of our private data is something that we all want, no matter whether it is on the cloud, our smartphone or our computer or laptop. When it comes to cloud storage services, they are protected with a password and two-factor authentication, and our smartphones are locked with patterns, passwords or pins, which ensure the safety of the data we keep within them. But when it comes to desktops and laptops running Windows, the only security methods we have are passwords, pins, picture passwords, etc., which aren’t that safe, as well. So why the security methods aren’t secure in the first place. Even the security methods can protect access you our PCs, the data in the hard drives or SSDs can still be accessed, if it isn’t encrypted.

But every cloud has a silver lining. You can safeguard the contents in your PC running Windows, with a USB thumb drive or anything of that sort to use it as a key to lock and unlock your PC for good. But Windows doesn’t have native support for allowing you to use USB drives as keys, and thus, you need third-party software to prepare the recipe.

There are a handful of programs which can be useful, but I will feature a freemium software here, which can be enough to get your job done if you are not looking for some premium high-end security for the data that resides on your computer.

Step 10: I know how cool it is going to be. The USB drive can also be used for other activities, apart from using it as a key for your computer. But make sure you don’t remove the key file that is present in the USB drive, as the screenshot below after you use the drive as the key for your computer.

You can even use an Android device to unlock your PC with KeyLock. I didn’t try it out, but that should work the same way as a USB device do.

KeyLock is completely free to use, however, there are Premium and Business editions, which are suitable for businesses. They don’t come with any features you will find useful if you want to use KeyLock for non-commercial purposes.

So that was it. Hope you find it useful. I would like to get your views in the comment section down below.
