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.

Optional Access permissions:
Microsoft Authenticator includes the following optional access permissions. All these require user consent. If you choose to not grant these optional access permissions, you can still use Microsoft Authenticator for other services that do not require such permission. For more information see
Accessibility Service: Used to optionally support Autofill on more apps and sites.
Location: Sometimes your organization wants to know your location before allowing you to access certain resources. The app will request this permission only if your organization has a policy requiring location.
Camera: Used to scan QR codes when you add a work, school, or non-Microsoft account.
Read the contents of your storage: This permission is only used when you report a technical problem through the app settings. Some information from your storage is collected to diagnose the issue.

Backup experience could be improved by prompting to restore from a backup when logging into the app for the first time (as in, if you didn't see the tiny text at the bottom to restore from backup and just logged in normally). Also, it would be nice to know that you are overwriting a previous backup by just turning the feature on. Overall, not intuitive when setting back up on a new phone.

Compared to some other Auth apps, this one offers some of the best, free account functional features! I think the most annoying part of it is the clunky UI. Instead of having to delete the back up and manually re-backup, it should auto sync. You should be able to categorize/group accounts together. I have *A LOT* of accounts (as a strong infosec proponent) so trying to find a specific one is a hassle. Need to add the ability to rename accounts. But otherwise, it works for basic Auth needs.

About half the time, it doesn't pop up a message to confirm my identity before my VPN times out. This causes me to have to re-auth over and over again. We recently started using the feature that pops up with a map of the login location and asks you to enter a number. This view has shown up a total of 3 times for me out of at least 50 attempted logins. I have to continually use another method to be able to authenticate. It's frustrating when I need to use this tool for work.
