Windows 10: How do I sign in into my Microsoft 365 account with my authenticator app?

I am able to sign into my Microsoft account, but I can't get through the identity verification. It keeps telling me to enter a code. I have access to my Microsoft Authenticator app, but it does not show me any codes. My app is not generating any codes for me to use."Enter the code displayed in the Microsoft Authenticator app on your mobile device". No matter what I do I am unable to access my account .

Microsoft Account authentication

After more research, I have found my answer. It looks like the issue was that Microsoft released a new Microsoft Authenticator app with the features first introduced in Microsoft Authenticator Beta. The new app received a prompt to approve access to my Microsoft
Account when signing on from a new PC, though I find it strange that the beta app wasn't directly upgraded to the new version of the app.

Microsoft now has three 2 step authentication apps available in the store for Windows 10 Mobile:

• Authenticator - original app from Windows Phone 8
• Microsoft Authenticator Beta - originally released to Windows 10 users when Windows 10 Mobile was only available on the Windows Insider program.
• Microsoft Authenticator - the official Windows 10 app no longer in beta

 

Can't Setup The Authentication App

It looks like you signed in your account instead of using the QR code when you added. I'd suggest removing the account first by tapping on the email address then the settings icon and Remove button.

To re-add the email address, I suggest following the steps in the "Sign in with a QR code" section in the link below. Also, make sure that the app is allowed to use camera in your phone's app permission.

New Microsoft Authenticator app version for Android - March 8

Two factor authentication (TFA) is easy, convenient, and secure when you use Microsoft Authenticator. 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 youve signed in with two factor authentication (TFA), youll have access to all your Microsoft products and services, such as Outlook, OneDrive, Office, and more.
