What's New in Microsoft Authenticator 6.7. 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. 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. Microsoft Authenticator also supports cert-based authentication by issuing a certificate on your device. You will need to register your device to your organization through the app and add your work or school account. Sometimes your work or school might ask you to install the Microsoft Authenticator when accessing certain files, emails, or apps. Either approve the notification sent to the Microsoft Authenticator, or enter the verification code generated by the app. When logging in, you'll enter your password, and then you'll be asked for an additional way to prove it's really you.

The app provides a second layer of security after your password. Microsoft Authenticator also supports multi factor authentication for work, school, and non-Microsoft accounts. After, you'll have access to all your Microsoft products and services, such as Outlook, OneDrive, Office, and more.

Your fingerprint, face ID, or PIN will provide a second layer of security in this two step verification process. Refer to this section to download and install the Authenticator app. You simply have to enter your username, then approve the notification sent to your phone. On the Add a method page, select Authenticator app from the list, and then select Add. Use your phone, not your password, to log into your Microsoft account.
