If you're a PC gamer, there's a good chance you're in some way involved with Valve's Steam service. If you're a Windows 10 Mobile user also, you're possibly not using the Steam Guard verification system thanks to its reliance on the mobile app, which isn't available on Microsoft powered phones.
And that's a problem. Steam Guard is something everyone who uses the platform should be using, but Valve doesn't seem to care if you don't own an iPhone or one of the hundreds of Android phones out there.
Thankfully, as in many cases with Windows apps, the developer community has come up trumps again and we have an app we can use on both Windows 10 Mobile and Windows Phone 8.1: the Unofficial Steam Authenticator.
There's not a lot to the app itself, which is fine. All it needs to do is give you your Steam Guard codes and access to trading, a feature which also requires the extra authentication.
A word of caution, though: If you already have it on another device on another platform, as I do, you'll still need that phone first to be able to generate a code to log in to this app. You then need to remove the authenticator from that phone before you can link this app.
But once you're in, it does exactly what it says on the tin. I'm not into Steam trading, so I haven't used that, but otherwise it does what you need it to do, when you need to do it. There doesn't seem to be any issue generating login codes, so all signs point to this one being a winner.
Once again the Windows developer community comes to the rescue. Grab it from the store now at the link below.
