Sign in is easy, convenient, and secure when you use Microsoft Authenticator. Use your phone, not your password, to log into your Microsoft account. You simply have to enter your username, then approve the notification sent to your phone. Your fingerprint, face ID, or PIN will provide a second layer of security in this two step verification process. After, you'll have access to all your Microsoft products and services, such as Outlook, OneDrive, Office, and more. Microsoft Authenticator also supports multi factor authentication for work, school, and non-Microsoft accounts. The app provides a second layer of security after your password. When logging in, you'll enter your password, and then you'll be asked for an additional way to prove it's really you. Either approve the notification sent to the Microsoft Authenticator, or enter the verification code generated by the app.  Sometimes your work or school might ask you to install the Microsoft Authenticator when accessing certain files, emails, or apps. You will need to register your device to your organization through the app and add your work or school account. Microsoft Authenticator also supports cert-based authentication by issuing a certificate on your device. This will let your organization know that the sign-in request is coming from a trusted device and help you seamlessly and securely access additional Microsoft apps and services without needing to log into each. Because Microsoft Authenticator supports single sign-on, once you have proven your identity once, you will not need to log in again to other Microsoft apps on your device.



  • Waste, more data waste

    By chukfkr
    Another bull crap app clouding up my data storage. Listen, our information is sold daily to the highest bidder. So don’t tell me all these measures are for our protection. When the ones protecting are the ones trading is redundant. Ask, why make us jump through the hoops for nothing tangible?

    Can’t figure out how to scan QR Code or enter a key to obtain the correct code for my Rockstar Social Club account. Deleted.
  • Worst app ever

    By ih8microsoft
    Kind of hard to add my Microsoft account, and verify it thru the app, if the app consistently asks me to verify my request thru the app. This is why no one likes Microsoft anymore. And, sadly, there is no way around this
  • Last 4 digits

  • It’s a no brainer!

    By Aaron L Peggs
    Let’s face it. We all expect our devices and all the personal information that is associated with them to be extremely secure, easy to quickly access, simple to manage, and we want it to be convenient and effortless to do all this across all of our devices. Right? Surely I’m not the only one who likes the peace of mind that tight security provides? And to have that benefit just a click away, plus the simplicity of logging onto a pc or any other device from my phone or vise versa, without the hassle of being bogged down with 30 different passwords for multiple accounts, is quite simply a must have! Especially if you are not very tech savvy like myself. The Authenticator app is exactly as one would expect from Microsoft, its easy to use and has a simple but effective way to let you log into nearly all your apps or websites. Just tap the user ID fill line which will initiate an auto fill of your choosing, the Authenticator then automatically launches and verifies its you, then pulls up the page you are wanting to go onto asks for your approval and you click approve, at which point it then takes you to the Authenticator app which verifies your ID one more time to ensure there’s no tracking activity. Even if there was a hacker on the hunt it’d be a futile effort because there is NO PASSWORD through the entire process which means there’s no reward for the digital prowler!! Finally and most importantly you’re seamlessly logged onto the page that you chose and away you go. Btw the entire process I outlined above in reality takes about 4 seconds at the most. I can’t find anything to criticize about this app or any changes I would suggest. It’s the most convenient, simple to use, security driven, device to device login verification tool I’ve ever tried. I’m not overstating this at all I’m just so impressed at the performance of this service it’s flawless! If you’re still on the fence about it maybe the fact that it’s a 100% free service may be enough to give it a shot 🙂 Once again Microsoft shows us why they are second to none. It’s pretty awesome to have a company that’s simplifying your digital needs, all the while striving to uphold the integrity and responsibility to protect your personal information. And all they ask for in return is for us to download it at no cost. Completely free no strings attached. NO BRAINER!
  • Update Wasn’t Shown...

    By rod.musselman
    Coincidentally, this app update wasn’t displayed in the App Store on my 512GB Apple iPhone XS Max now running iOS version 12.3.1. Only after I deliberately selected this app in the App Store did I notice that an update was available. There’s the right way to do things, the wrong way to do things, and then there’s the Apple way to do things. Love my iPhone & ALL of my Microsoft apps!
  • Watch app is not up to park with Phone app

    By ItsTheArsonist
    I don't believe I've ever been able to get the Authenticator app to work properly with push notifications on the Apple Watch. I get the notification on the Watch just fine. I approve it, select the correct number shown on the screen, then it thinks for a second and says "Something went wrong." I pull out my phone and perform the same steps and it works great, Face ID and all that goodness on the phone. This issue has persisted two different phones, multiple app updates, and different IOS builds. Not sure if MS will ever fix it but I'll hold out hope for them to fix the otherwise great service.
