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.

    if someone is telling you to approve the code don’t do it, it will allow them to get onto your account and take money or steal your account

    Hello, This is a PSA for parents. This app can be used to authorise account info to be shared. A person tricked my son into download this app and sharing my account info. In minutes purchases were made on my Xbox account off my CC. Took awhile to to recover my Xbox account and they deleted my Microsoft account email. So watch out! Don’t know much about the app except this was able to easily send my info to someone else password and all! I’m sure if used correctly it’s just fine. Not downing the app just a PSA.

  • Hate the new version, why add a click?

    By cjstolte
    What is it that you do with this app 99% of the time? Get your 2FA code! Guess what’s no longer on the opening screen. Your 2FA code!!!! How is that user friendly when that is the main thing to come to the app for. Bury it down a click, I always grunt when I have to enter my code by opening an app let alone have to then do an extra click. (I know the value in 2FA and try to set it up with every account I’m able, but I still grunt haha)

  • Not Happy at All

    By Electrokid08
    So I’ve been using this app for around a year or two and a few months ago it started refusing to open and wiped all of its account codes, now if any one of the accounts it was linked to log out at all, I get permanently locked out and lose all data on said accounts.
