Can't Access Microsoft 365 Account Due to Authorization Code

Question

Hi!

My credit card expired and I need to update it to keep using my Microsoft 365 account. However, to sign into it, I need to access the code displayed in my Autheticator app. However, I can't log into the Autheticator app to get the code, without the code.

Also, when I try to reach out to support about the issue, they say I have to access support through my Microsoft 365 account. But I can't get in without the code.

Every option I try, I keep going in circles.

Who can I contact, and how can I solve this issue?

Thank you!

Hello @Emily Rusu,

Thank you for posting your question in the Microsoft Q&A forum.

Regarding the issue where you are unable to complete the receive verification code for Administrator login, which results in the inability to reduce licenses. Please kindly check whether your tenant has another Global Administrator who may be able to assist you with this issue?

If other user still holds the Global Administrator role, please kindly follow these steps:

• Sign in to the Microsoft Entra Admin Center using an account that has at least the Authentication Administrator role.
• Navigate to Entra ID > Users. 
• Select the user whose MFA authentication methods you wish to reset, then choose Authentication methods. 
• Select Revoke multifactor authentication sessions, and then select Require re‑register multifactor authentication. 
• After completing these steps, the user will need to set up MFA again. You can do this by signing in and configuring MFA through the Microsoft Authenticator app on mobile device.

If you are the only administrator in your organization, you will need to contact the Microsoft Data Protection team for further assistance. Please locate the appropriate support phone number for your country or region and contact Microsoft Support so the frontline team can raise a service request on your behalf: Customer service phone numbers

When calling the support number, the experience may vary depending on your country or region:

• In some regions, you may hear an automated message for approximately 30 seconds. You can ignore this message and wait for the prompt, then select “1” for Business email user and “1” again for Technical support.
• In other regions, you may be guided through an automated conversation similar to the following:
  • The system asks what issue you are experiencing → Authenticator
  • Product in use → Office 365 for Business
  • Account type → Company account
  • Administrator status → Yes
  • Are there other administrators in the organization? → No
  • Proceed to create a service request → Yes

If your Office 365 Business or Education subscription was purchased through a partner or reseller, and you are unable to open a service request directly, please contact your reseller’s support provider and ask them to raise the service request on your behalf.

Alternatively, if you are unable to reach support by phone, you may create a temporary trial tenant to submit a support request for the block access tenant through the Microsoft 365 admin center. You can start with a trial license here: Microsoft 365 Business Plans and Pricing | Microsoft 365

Important: Please remember to cancel the trial subscription after your original account issue is resolved to avoid any future charges.

Note: Please understand that as a forum moderator, my primary goal is to provide helpful guidance and support through general troubleshooting steps. While I don’t have access to internal systems or test devices required to resolve backend/account issues, I truly appreciate your understanding of these limitations.  

Thank you for choosing Microsoft, and I am looking forward to your response. If anything is unclear, please don’t hesitate to reach out to me.

Answer 2

To regain access to your Microsoft 365 account when you're unable to use the Authenticator app, you have a couple of options:

1. Contact Microsoft Data Protection Support: Since you are the sole administrator of your account, you can reach out to Microsoft’s Data Protection team directly via phone. When you call, explain that you cannot access your account due to issues with the Authenticator app. Be prepared to provide details about your account and confirm your identity.
2. Create a Temporary Account (Trial Tenant): If you are unable to reach support through the phone, you can create a new Microsoft 365 trial tenant. This will allow you to access the Admin Center and submit a support ticket requesting assistance with your locked account. Make sure to clearly state that you are locked out of your original account and provide necessary details.

Here’s a brief outline of how to navigate the support hotline:

• When prompted, select options indicating you are a business user and need technical support.
• Clearly state that you are the only administrator in your organization and need to create a service request.

These steps should help you regain access to your account and update your credit card information.
