I retired my Thinkpad a while ago for a newer and a faster laptop. Even though I would not want to go back to my previous computer but I do miss one feature on my ThinkPad - the fingerprint sensor. It was a small feature that I was so dependent on it, I had almost forgotten my Windows Password. There are multiple apps (like MacID) to unlock Macbook with an iPhone using Touch ID, proximity, or another gesture. And they all work flawlessly. Yes, the same is true for Windows and Android, but the process never been as reliable as Apple ecosystem. For a long time, I was looking for a reliable way to unlock my Windows PC without the need for a password, I even thought of ordering a USB biometric module but scrapped it because I don’t like those dongles and wires. I wanted something quick, and wireless. Thanks to XDA’s user Andrew-X, if you have an Android device with a fingerprint scanner (which most smartphones do these days), you can use it to unlock Windows 10. I had to check it out and surprisingly, it works really well. Let's install it on our computers. Also Read: How To Watch HBO Now outside of the US

All you need is both your Windows PC and Android connected to same WiFi network. I did a thorough testing of the app and it works great. It isn’t the fastest way to unlock your Computer but it is fairly efficient.

First things first, you’d need a computer running Windows Vista or above and an Android device with a fingerprint sensor running Android 6 or above.

Set up Windows

Install the Windows credential module on your computer by choosing the appropriate version. Windows Credential Module has both 32-bit and 64-bit versions, so select accordingly. While installing the module, it would ask you to grant an exception in the firewall, which would allow the module to receive the data packet while locked out of the system.
