To be able to unlock your Windows 10 device with a compatible Samsung smartphone, the first thing you need to do is download Samsung Flow from Google Play (hit the source link). You also need to have Samsung Flow installed on your Windows 10 device—it is available in the Windows Store. Finally, make sure you are running the Windows 10 Creators Update (or newer, when applicable) for this to work.
Once the app is installed on both your smartphone/tablet and Windows 10 device, fire it up on both gadgets. On your Windows 10 device, choose your phone and click the pair button. Next you will need to confirm the passcode on both devices, which will complete the Bluetooth pairing. Next, click the "Register device" button, then confirm the passcode on both devices again. Finally, enter your PIN. From here on out you can use your Samsung phone/tablet to unlock Windows 10 with your fingerprint.
