Why is Microsoft Authenticator Stuck in a Login Loop?

Mr 20 Reputation points

I'm having trouble signing in to my Microsoft account using Microsoft Authenticator on Windows 10. I also use Microsoft Authenticator on my Android phone.

Here's what's happening:

  1. When I attempt to log in, I receive a message that says, "We'll send a sign-in request to your phone to sign in with my email address.
  2. I click the "send notification" button on my computer.
  3. On my phone, I'm asked to tap the number displayed on my computer screen to sign in without a password. I do this, and it confirms the number I selected on my phone is correct.
  4. However, back on my computer, I get stuck in a loop with the message, "We'll send a sign-in request to your phone to sign in with my email address." This cycle keeps repeating, and I can't log in.

It's worth noting that I can sign in to my account on Windows 10 and my Outlook account without any issues. I'm specifically having this problem with Microsoft Authenticator(Microsoft store, Xbox app, etc).

In summary, Microsoft Authenticator is stuck in a continuous loop, preventing me from logging in.

I've attempted some fixes

  1. Signed out and then back in again on the Microsoft Authenticator app.
  2. Reinstalled the Microsoft Authenticator app.
  3. Reset my phone.
  4. Reset my computer.
  5. Removed the two-step authenticator from my Microsoft Account and then re-enable it.

This is the prompt on my computer I get in a loop.

    Reinstalled the Microsoft Authenticator app.

    You can restore from an authenticator cloud backup (assuming there was one) but make sure no accounts have been added to the newly install app. Then sign on with recovery account to do the restore.

    You can recover your account credentials from your cloud account, but you must first make sure that the account you're recovering doesn't exist in the Microsoft Authenticator app. For example, if you're recovering your personal Microsoft account, you must make sure you don't have a personal Microsoft account already set up in the authenticator app. This check is important so we can be sure we're not overwriting or erasing an existing account by mistake. https://support.microsoft.com/en-us/account-billing/back-up-and-recover-account-credentials-in-the-authenticator-app-bb939936-7a8d-4e88-bc43-49bc1a700a40
