Soon your Samsung Galaxy's fingerprint reader will unlock your Windows 10 PC

Security within arm's reach.

Samsung is telling Galaxy device users they’ll soon be able to use their phone’s fingerprint sensor to unlock nearly any Windows 10 PC.

The Samsung Flow app currently lets users unlock a Galaxy TabPro S 2-in-1 with the fingerprint sensor on a Galaxy S7, S7 Edge, S6, S6 Edge and Edge+, Note 5, and A7 and A5 devices.

After the Windows 10 Creators Update, however, that login feature will expand to all Windows 10 PCs that have the hardware to support it, as first reported by SamMobile.

“Samsung Flow is compatible with TabPro S now. But it will support all Windows 10 PCs from Windows 10 next major update (estimated early April),” a Samsung representative said in response to a user review on Google Play.

Samsung’s set up requires the use of the Samsung Flow app on your phone and a special utility installed on the Windows machine to unlock. Unlocking your Windows 10 PC with your Galaxy's fingerprint reader also requires the use of Bluetooth on both devices, and NFC on the smartphone.

The story behind the story: Samsung’s solution is, as the company says on Google Play, a “neat trick,” but a native solution would be better. Microsoft added that capability with the Anniversary Update’s Windows Hello Companion Device Framework. So far, however, we’ve seen mostly fitness trackers and security devices like the Yubi Key take advantage of the authentication feature. Nevertheless, Microsoft has, on several occasions, talked about using Android and iOS smartphones to unlock your Windows 10 PC—most recently in September during the Microsoft Ignite conference. The company has also been testing PC unlocks with a Windows 10 Mobile authenticator app.

Perhaps the Creators Update will finally bring smartphone unlocks to everyone who has a Bluetooth-enabled PC and phone. If so, that will finally bring Windows 10 up to parity with Chrome OS.

A smarter way to print for busy small business owners, combining speedy printing with scanning and copying, making it easier to produce high quality documents and images at a touch of a button.

I've had a multifunction printer in the office going on 10 years now. It was a neat bit of kit back in the day -- print, copy, scan, fax -- when printing over WiFi felt a bit like magic. It’s seen better days though and an upgrade’s well overdue. This HP OfficeJet Pro 8730 looks like it ticks all the same boxes: print, copy, scan, and fax. (Really? Does anyone fax anything any more? I guess it's good to know the facility’s there, just in case.) Printing over WiFi is more-or- less standard these days.

I’d happily recommend this touchscreen laptop and Windows 10 as a great way to get serious work done at a desk or on the road.

Ultimately, I think the Windows 10 environment is excellent for me as it caters for so many different uses. The inclusion of the Xbox app is also great for when you need some downtime too!

For me, the Xbox Play Anywhere is a great new feature as it allows you to play your current Xbox games with higher resolutions and better graphics without forking out extra cash for another copy. Although available titles are still scarce, but I’m sure it will grow in time.
