Remote Fingerprint Unlock is a simple app that lets you unlock your PC by using your fingerprint on your Android phone.

At least, when using the corresponding app for both Android and Windows 10. So even if your computer doesn't have a fingerprint reader, you can now use the one on your phone to unlock it.

You can set your Android phone to unlock itself when it's in your pocket, while you're near a certain location, when it hears your voice, and more.
