Question details

The user is unable to access a corporate Microsoft 365 admin account due to repeated sign-in prompts that occur even after correctly entering the password and passing the Authenticator app verification.

Product: Microsoft 365
Device & OS: not provided
Scenario: Attempting to log into a corporate Microsoft 365 Admin portal to manage tenant settings.
Observed behavior: The authentication process appears to succeed, but instead of granting access, the system loops back and repeatedly prompts the user to sign in again.

Before you start

Determine whether you are the sole global administrator for your organization's tenant or if there is another active administrator who currently has access.

Solution 1Recommended

Reset Authentication Methods via Another Administrator

Use this method if your organization has more than one administrator who can still access the Microsoft Entra ID admin center.

If you are not the only administrator, the fastest way to resolve a login loop caused by corrupted MFA tokens is to have a colleague reset your authentication methods.

Log into Microsoft Entra ID

Ask the secondary administrator to log into the Microsoft Entra ID (formerly Azure AD) admin center using their active credentials.

Locate the affected user

Navigate to 'Users' and then click on 'All users' in the left-hand navigation pane. Search for and click on your locked-out admin account.

Reset authentication methods

Select 'Authentication methods' from the user's profile menu. Choose 'Require re-register MFA' to force the system to prompt you for a fresh setup during your next login attempt.

Solution 2

Contact Microsoft Data Protection Team

Use this method if you are the only global administrator for your tenant and are completely locked out.

Frequently Asked Questions

Why does my Microsoft 365 admin account keep looping back to the login screen?

This loop usually occurs due to a synchronization glitch with Microsoft Entra ID authentication methods, corrupted browser cookies, or a breakdown in the multi-factor authentication (MFA) token validation process.

Can I use the self-service password reset if I'm stuck in an MFA loop?

A self-service password reset will only change your password. If the issue is related to the Authenticator app or MFA token looping, resetting the password will not bypass the multi-factor authentication prompt.

How long does it take for the Microsoft Data Protection Team to recover my admin account?

Recovery times can vary significantly. Because Microsoft mandates strict security and identity verification processes to prevent unauthorized access to corporate tenants, it can take anywhere from a few days to a couple of weeks.
