Get Steam Guard on your Windows Phone with this simple app

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.

  • FINALLY!!
  • It's not official, and u say finally!!?
  • I say finally in "Finally we have a way to use Steam guard".
  • App is in store since 6 months. Congrats
  • To all those paranoid peeps who are afraid to use this..Im an Indian, I got about 100 recent games (AAA as well as Indy) and i have been using this app for past 4months..and i have had zero issues so far. I formatted my phone once, so i lost the authenticator activation code it gives at start and my account got locked until i removed the authenticator via email and sms...this is as safe as it gets. From personal use, id recommend it to anyone without a doubt (reason to mention indian-we are more paranoid than you are about money...ask any Indian who still won't swipe his card at stores) lol
  • I've been using this for a while.  It' simple and being able to use Steam Chat is huge.
  • Security?
  • The code is open source, so you can verify yourself. It's been checked by people on forums and declared safe. No guarantees though :P
  • Is there anything like this for FFXIV one-time passwords? :P
  • I know we normaly use 3rd party aps on Windows Mobile, but I'm a little hesitant for an app that I have to put my steam credentials in. Does anybody know how the backend of the app works?
  • Its completely safe, checkout reddit thread: https://www.reddit.com/r/Steam/comments/3xh0yz/unofficial_steam_authenti... He even posted source for people who understands the code to make sure he is not stealing data. 
  • Nothing is ever "completely safe". It'll take more than a reddit thread to convince me.
  • Dont be so paranoid.
  • The application is open source, so you can look through the code yourself. There is always the possibility that the app published differs from the app source code on Github - in that case, you can review the code yourself, compile the app, and push it on your phone yourself. This is about as good as it can get, arguably even safer than trusting Valve's own client.
  • Yeah, with how big a problem fraud is with third-parties and Steam, I wouldn't touch this with a ten-foot pole.
  • Gosh..dont be such an ignorant and read. https://www.reddit.com/r/Steam/comments/3xh0yz/unofficial_steam_authenti...
  • Yeah, a 5 month old thread which cannot be commented on. Pretty convincing, Sherlock.
  • ???
    So 1 day old thread would convince you more? It is as old as the app itself. 5 months. And I dont know what the hell are you talking about with commenting, I can comment. So make sure you are logged in lol.
  • When will the official app will release??
    Why valve not support us ??
    We need to tell them about release official app to our platform, what do u think ??
  • Never. They dont care about WP or its users People have told them... and they still dont care.
  • Hell no I would rather trust my steam credentials stored on my friends android phone and that's how I am using it
  • https://www.reddit.com/r/Steam/comments/3xh0yz/unofficial_steam_authenti...
  • You are better off linking to the source code page and describing that.
  • So when your friends phone gets stolen, bye bye your Steam account, right? You may as well not have Steam Guard turned on if that's how you're doing it. Seriously.
  • What about if his own phone could run the app and gets stolen? What's the difference between the two cases? Why does it make a difference if it's his phone or his mates? :S
  • The difference is control. If you have control of a device that has your secured material on it, then it's better than if someone else has your stuff. You can make sure you treat the phone how you will. Will the other person be as careful? Will they go to sites that install a virus? What happens if they buy a new phone because their old one got dropped in a can of paint? You having control of your things is normally better than others having it.
  • And also the added advantage of remote locking or erasing.
  • How safe is this?  I've been on the fence about this for a while and I've read all the reviews. I'm a little worried about security.
  • Considering someone would need your phone and your phone alone to access your account, I'd assume it's the same as Valve's app. Steam Guard only allows one phone to link to it at a time. When it's active someone would need your phone at the time they try to log in to get the code. And that's about the size of it. Unless someone can unlink your phone, which again, requires your Steam Guard login, no-one could change it. Personally I'm more worried about Valve screwing me over.
  • I think he means with worried about security that you're basically giving a 3rd party app your username, password and steam guard. If this app isn't secure or if the maker has ill intent you could lose your account.
  • Its pretty much safe. https://www.reddit.com/r/Steam/comments/3xh0yz/unofficial_steam_authenti...
  • Stop linking to that cancerous website.  
  • I think windowscentral wouldn't advice this app if it wouldn't be safe. Judging the reviews it's like 4.5 outa 4 and nobody complained. All set and good to go. Finally I have no reason to change to Android anymore
  • Stop commennting such cancerous comments.
  • Haha Posted via the Windows Central App for Android (V10 or 5x)
  • Personally I would not trust the security of my Steam account to a third party app; the sad part is Valve is forcing people into using less secure option because of their disregard for account security for all its users not just iPhone and Android owners. @WindowsCentral, have you reached out to Valve for comment as to why there is no Universal Windows 10 app?  
  • Using it for months since the author created topic about it on reddit and no problems so far !! You dont have to worry about stealing your credentials. Its completely safe. Good to have people like these when Valve is ignoring and discriminating their users.
  • Thanks for the link! Hadn't seen that personally but the Store reviews seemed good enough to give it a shout!
  • Yeah, one developer on reddit looked through the code and confirmed it is SAFE.
  • thats nice, downloading it right now!
  • Finally!
    A big f&&k to Valve and a big thanks to the developer!
  • I've stocked up on popcorn for that eventual day I read the WCentral headline: "Hundreds of  User Steam Accounts Hacked via Unofficial Steam Guard App for WP"
  • Third party authenticator apps aren't new. Authy, for example. Sure it's not on Windows, but I use it on everything else I have just because it's cross-device and syncs everything nicely. (And you need this app for Twitch). Third party app, never had any issues with it.
  • Do we really need this???????
  • If you use Steam, yes. You do. You can't trade on Steam without it for one.
  • Of course you can, you just have to wait 15 days.
  • You cant. This is second or third untrue statement you made so far in this topic. I wont even try to understand your logic with spreading lies. Thats why I called them discriminating, because without it you cant trade/bet anything related so they are forcing you to use certain OS.
  • You can, you've made a fool of yourself and should apologise.
  • Having Steam Chat on mobile made me instantly get this, thank you developer!
  • I'm using it for months... Very good. Works as expected.
  • Interesting this article popped up. I was actually hesitant about using this app, but I guess I can give it a try.
    Also FYI there is a petition on change.org for this thing which I just recently signed.

  • Give up. Better chance that hell freezes over than Gabe Newell develops app for Windows. He hates Windows.
  • Yes that's true and no secret. So sad. What is annoying is the fact that he hates that platform which made him rich and which made steam so successful.
  • Cause Gabe develops the Steam apps....
  • Too risky since not official.i have over 1100 game on my account and won't risk a ban. Those 3rd party apps use a middleware like SteamKit which communicate directly with the steam servers which is a great security risk and not 100% legal. I released a Steam app myself which includes nearly everything from the official web API and I know that chat and steam guard are not supported. SteamCenter was one of the first fully featured steam apps for windows phone and it supported chat for a short time before the functionality was removed by Valve.
  • when i press the "link" button, it does nothing, it just flashes add authentication for 1 sec and then back to link authentication :(
  • Just look in the store directly?
  • dev could finally update the app. still crashes randomly
  • This is so awesome :)
