Hi @Fernanda Fernandes

Thank you for reaching out. 

First, I’d like to clarify that this is a user‑to‑user support forum, and we are not Microsoft Support. Moderators participating here do not have access to backend systems, nor can we directly intervene in Microsoft product functionality. Our role is limited to providing technical guidance and sharing best‑practice recommendations based on reported issues, requests, and scenarios.     

Based on your description, I understand that you still know the password for your Microsoft 365 Developer tenant administrator account and can successfully complete the primary sign-in process. However, you no longer have access to the Microsoft Authenticator app that was previously registered for MFA and is required to approve the sign-in request or provide the verification code. Additionally, there are no alternative authentication methods configured or available for account verification. As a result, you are currently locked out of your sole admin account for your Microsoft 365 Developer E5 tenant.  

In this situation, there are two official paths you can take to regain access to Developer tenant:  

1.Please visit the following page and reach out to phone number via: Customer service phone numbers - Microsoft Support  

From what I know, you will need to get past the initial AI system to reach the live support team. You can refer to the guide below for tips on how to get through more easily:  

(When you call the support number, you may hear an introduction of about 30 seconds such as "you can visit the link...". You can ignore this introduction and wait until you are presented with the options. Then press "1" as a business email user, and again "1" for technical help.)         

In some countries, it is an automated conversation like:  

IVR: What kind of problem are you concerned about?        

You: Authenticator.        

IVR: What kind of product do you use?        

You: Microsoft 365 for business.        

IVR confirmation: education or company account?        

You: For companies        

IVR: Are you an administrator?        

You: Yes.        

IVR: Do you have another administrator in your organization?        

You: No.        

IVR: Do you need a... Service request? 

You: Yes. I need to create a ticket. Please send me directly to the Data Protection Team. 

2.If Method 1 does not resolve the issue, you may consider registering a new tenant by signing up for a trial subscription using this link. This will allow you to create a new tenant by following the on-screen prompts.  

Once the new tenant is set up, you can access the Microsoft 365 admin center and submit a support ticket requesting assistance from the Data Protection team regarding your previous tenant.  

Assuming you have successfully created the trial tenant, navigate to the Microsoft 365 admin center and click the Help & support icon to raise a ticket. The support agent will be able to create a case under the affected tenant and subsequently transfer it to the Data Protection team, who can assist you in regaining access.     

Please mention that you are raising ticket on behalf of the affected tenant that you do not have access to. The support team will help you to create ticket on the affected tenant then later on the Microsoft Data Protection team will assist you.  

Note: This process will take more time than usual (7-14 working days) for your account to get access again as Data Protection is always overwhelmed with the number of tickets. As I am forum moderator, I do not have access to Microsoft internal system to assist or push this process to be quicker.  

On the other hand, if you do create the trial and it resolves the issue, please remember to cancel the subscription afterward to avoid any related charges.   

I understand that this entire process can feel long and complicated, and I truly appreciate your patience while working through it. These steps are in place to protect the security of your account, so I hope you can understand why they are required. I sincerely hope you’ll be able to regain access to your account soon. If you need help at any point, or if you have any questions during the process, please feel free to reach out, I’m always here and happy to assist.    

Appreciate your patience and understanding.
