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.

A must have app.

This app is a must have to app two step authentication to your Microsoft account it’s fast and easy to set up.
Now even more better with auto back up this means if you get a new iPhone you can easily switch to the iPhone with out the need to turn off two set authentication on you account and they turn back on.

Backup is a good feature but needs improvement.

Great to see we can now backup our authentication entries but we really need to sync the same entries to all our devices when we add a new entry without having to uninstall the app & re-add it.
Also when adding the app it will overwrite a backup created on another device with the one from the newly added device which imo defeats having a backup.

Ok but what are in the updates?

The app works fine and provides secure two-factor with for Microsoft account.
But I have to ask - what are in the updates? Saying “we’re always working on new features and improvements” is not a chandelier. This is a security app - please list what has changed between version. I will not update to a version I know nothing about.
