The user needs to regain access to a Microsoft 365 Business administrator account experiencing MFA issues and needs to update the billing payment card.

How to Access Your Microsoft 365 Business Account and Update Payment Methods

Product: Microsoft 365 Business
Device & OS: not provided
Scenario: A business administrator is locked out of their account due to authentication failure and must restore access to change an expired or incorrect billing payment method.
Observed behavior: Authentication cannot be completed, preventing login to the admin center, which consequently blocks the ability to update business payment methods.

Before you start

Verify if there is another active Global Administrator in your Microsoft 365 tenant, and have your company's registered domain name or tenant ID ready before contacting support.

Solution 1Recommended

Reset Authentication via Another Global Administrator

If your organization has multiple Global Administrators, the fastest way to regain access is by having a colleague reset your authentication method.

Microsoft 365 allows Global Administrators to manage authentication settings for other users, including fellow administrators. This is the most efficient method to bypass a lockout without waiting for Microsoft Support.

Log into Microsoft Entra ID

Have the secondary Global Administrator sign in to the Microsoft Entra ID (formerly Azure AD) admin center.

Locate your account

Navigate to the 'Users' section and search for your locked administrator account.

Reset authentication

Select 'Authentication methods' from the user profile menu and click on 'Require re-register MFA'.

Set up MFA again

Sign in to your administrator account; you will now be prompted to set up your multifactor authentication method from scratch.

Reset Authentication via Another Global Administrator

Security Tip: Always ensure you have at least two Global Administrators in your organization to prevent being permanently locked out if one authentication device is lost.

Solution 2

Contact Microsoft Support for Account Recovery

If you are the only Global Administrator in your organization and cannot pass the MFA prompt, you must contact Microsoft Support to verify your identity.

Solution 3

Update the Payment Card in the Admin Center

Once you have successfully regained access to your Microsoft 365 Business account, you can update your billing details.

Frequently Asked Questions

Can I simply edit the existing credit card number on my Microsoft 365 account?

No. For security and compliance reasons, you cannot directly edit the card number of an existing payment method. You must add a new payment method with the updated card number and then replace the old one.

Does my new payment card need to be from a specific country?

Yes, generally the new payment method must be issued in the same country or region where your Microsoft 365 tenant is registered.

What happens if I am the only Global Administrator and get locked out?

If you are the sole administrator, you will not be able to reset your own MFA. You must contact Microsoft Support by phone, verify your identity with the Data Protection team, and have them manually restore your access.
