Action required - Infinite loop MFA when trying to login

Question

Action required - Infinite loop MFA when trying to login

Sven Bemmann 10

Hello,

I asked this qustion at 

Unfortunately, I can no longer log in to the admin center or EntraID with a global admin account. The MS MFA app was already set up, we had problems logging in yesterday and I seem to have killed it when I tried it. Yesterday I was still able to log in to the admin center with the user without any problems. The following steps are now displayed:

Action required

Your organization needs additional security information. Follow the instructions to download and set up the Microsoft Authenticator app.

Further:

Protect your account

Method 2 of 2: Done!

Successful!

Very good! Your security information has been successfully set up. Click "Done" to continue signing in.

Default sign-in method: Authenticator app or hardware token code.

3x Microsoft Authenticator

e-mail

-> Click on Done and the process starts again.

Since this question has already been asked several times by other users, I am also hoping for support in this way.

Thank you for your suggestions

Sven Bemmann.

Hello @Sven Bemmann ,

Thank you for reaching out Microsoft Q&A.

I understand your stuck with Infinite MFA while login to azure portal.
Do you have any other Global Administrator accounts in the tenant? If so, please log in to that Global Administrator account, check the user's sign-in logs, and provide a screenshot of the basic information from the user sign-in logs. Additionally, provide a screenshot of the Conditional Access settings, similar to the attached images below.

Please check whether the Per-User-MFA has been enabled for the affected admins in your tenant and also provide the screenshots for the same.

I also have the same issue. I just updated my iPhone to iPhone 16 and the authenticator app did not have my old account every time I try to login it says go to the Authenticator app and put the code but it’s a infinite loop.

Hello @Goutam Pratti ,

thanks for your answer. We do not have another admin-account. Maybe we should do this in the future. But now, I have no access to the tenant.

Regards. Sven

Hi @Sven Bemmann ,

Thank you for your prompt response.

Could you please confirm that if any one of the other users in your tenant can login to Entra admin center or all the users in your tenant are unable to login to Entra admin center?

You can close this thread. Our CSP Distri could revoke the admin's MFA an I'm able to lockin again.
