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.
We've made some improvements to help you securely access additional apps and services without needing to sign in again.
Ratings and Reviews
2 factor authentication not 3
Some reviews are saying the app need a passcode. No then it would be 3 factor authentication not 2. The passcode to access your phone is essential to protection of all apps and data on the device. Having every app protected individually would be unusable.
This is a secondary authentication in a different format than your first authentication which is your login and pass word on Microsoft cloud services. It prevents you giving your password put in a phishing attack and being compromised. If they have your password and your phone and the passcode to unlock your phone then who cares if the app does not have its own passcode? You do have a passcode on your phone don’t you?
Excellent app with one notable flaw
This is an excellent Authenticator app, with one flaw - the passcode/Touch ID for the app can be bypassed by double tapping the home button. Please fix.
Watch app doesn’t work.
I have the latest update of the watch app running on WatchOS 5.0. I get prompted to authorize, but tapping approve does nothing. I still have to launch Authenticator on my phone and approve from there.
