Unable to access my admin account after changing phones

Question

Unable to access my admin account after changing phones

Allien Surface 0

I’m having trouble getting back into my Microsoft 365 admin account and could really use some advice.

I’m the sole admin for my organization, and I suddenly found myself unable to sign in. The sign-in process asks me to verify my identity through MFA, but I can’t get past that step.

I recently switched to a new phone and installed Microsoft Authenticator again. However, the verification process doesn’t seem to work, and I’m still locked out of my account.

The biggest problem is that I’m the only admin, so there’s no other administrator who can reset my MFA or help me regain access.

Has anyone run into this issue after switching phones? What would be the best way to recover my account in this situation?

Thanks in advance for any suggestions.

Dear Allien Surface,

Based on your description, you are the only Microsoft 365 administrator, you changed phones, and your Microsoft Authenticator MFA registration is no longer available, leaving you unable to complete the sign-in challenge.

The most effective solution in your situation is contact to Microsoft Support team, the agent will be able to create a ticket for you under the affected tenant and then transfer this ticket to Data Protection team who could help you to regain access. You might need to contact Microsoft Support team via phone service number: Customer service phone numbers - Microsoft Support.

To help you navigate the automated phone system (IVR), here's an example of what the conversation might look like:

IVR: What kind of problem are you worried about?

You: Admin account locked

IVR: What kind of product do you use?

You: Office 365 for business

IVR: Does it count for education or business?

You: For Business

IVR: Are you an admin?

You: Yes

IVR: Do you have another administrator in your organization?

You: No

IVR: Need a service request?

You: Yes

This should help you connect with a live support agent who can help you directly.

If you can't create a support ticket during the call, I recommend creating a temporary tenant account and submitting the support request from there. To create a new tenant, follow these steps:

Visit Office 365 E3 - Enterprise Collaboration and Productivity | Microsoft
Select any plan and click Try for free.
Complete the setup to create a new tenant.
Ticket support: In the Microsoft 365 admin center>support>help & support. You can create a support ticket: https://admin.microsoft.com/#/support/requests

Important: Please remember to cancel the trial subscription once your issue is resolved to avoid any charges.

I understand that this issue may take some time to resolve and could impact your workflow. However, the following solutions have been effective in resolving Microsoft Authenticator issues.
