About this app

Use Microsoft Authenticator for easy, secure sign-ins for all your online accounts using multi-factor authentication, passwordless, or password autofill. You also have additional account management options for your Microsoft personal, work or school accounts.

Getting started with multi-factor authentication

Multi factor authentication (MFA) or two factor authentication (2FA) provides a second layer of security. When logging in with multi-factor authentication, 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 one-time password (OTP) generated by the app. The one-time passwords (OTP codes) have a 30 second timer counting down. This timer is so you never have to use the same time-based one-time password (TOTP) twice and you don’t have to remember the number. The one-time password (OTP) doesn’t require you to be connected to a network, and it won’t drain your battery. You can add multiple accounts to your app, including non-Microsoft accounts like Facebook, Amazon, Dropbox, Google, LinkedIn, GitHub, and more.

Getting started with passwordless

Use your phone, not your password, to log into your Microsoft account. Just 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’ve signed in with two factor authentication (2FA), you’ll have access to all your Microsoft products and services, such as Outlook, OneDrive, Office, and more.

Getting started with autofill

Microsoft Authenticator app can also autofill passwords for you. Sign-in on the Passwords tab inside the Authenticator app with your personal Microsoft account to start syncing passwords, including the passwords saved in Microsoft Edge. Make Microsoft Authenticator the default autofill provider and start autofilling passwords on apps and sites you visit on your mobile. Your passwords are protected with multi-factor authentication in the app. You will need to prove yourself with your fingerprint, face ID, or PIN to access and autofill passwords on your mobile. You can also import passwords from Google Chrome and other password managers.

Microsoft personal, work or school accounts

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.

Update 6/22: finally the authenticator worked!!! Now, the problem is with Samsung popup notifications of whatever you did last. It hangs on the screen just right to cover the number I need to select on the authenticator! It was incorrect so tried again & guessed correctly. You can tap over the popup but can not see. It takes a very long time to go away. If you copied text prior, it says so; if you approved something, it says so. Everything you did last popups on bottom of screen, even over keybo

So far pretty good. One caution; If you have reset your mouse/TB to a left hand orientation you will probably have trouble logging in through this app. Until you figure out that it calls for a log-in/verification BEFORE the mouse settings etc. are loaded. Using the wrong button WILL NOT let you log in. It will just set there and look back at you blankly.

Works as described... I have had problems with other authenticor apps I've tried l maybe 3 or 4 other apps which sometimes can get me confused. I have several accounts with Google & Outlook ect. This one is pretty easy to use & works great everytime, especially when I need to sign into my laptop it just sends the verification to my cell-I click the button and it works just like it's supposed to! Thanks developers! Keep up the good work 🙂
