How to unlock any Windows 10 PC using a Samsung phone [Updated]

Much like Apple’s Handoff feature, Samsung’s Flow app lets you switch between different devices seamlessly. It originally only worked on Samsung phones and tablets, including the Windows 10-based Galaxy TabPro S, but an update means you can now use your smartphone to unlock any PC running the Windows 10 Creators Update.

You can also use Flow to perform other useful tasks, such as checking notifications across devices, and replying to messages directly.

Samsung revealed it was planning to make this change back in February and estimated the feature would roll out in April. In the end it took quite a bit longer to arrive, but it's here now, and setting it up takes seconds.

The process uses Bluetooth and Windows Hello, and you'll need a Samsung phone running Marshmallow or higher, or Samsung tablet running Nougat or higher.

Download the latest version of the Flow app on your PC/tablet and phone from here. In the app on your PC, select your phone and click the Pair link. Confirm the passcode on both devices and the Bluetooth pairing will complete. Click 'Register device' and enter your Windows PIN. Confirm the passcode on both devices again, and enter your PIN once more. That's it, you're all done.

[Update: Flow is finally back up on the Windows Store]
