Trouble logging in to Authenticator App(Not able to log into new browser and etc. at all)

Songyi Kim 0

Hello Microsoft Support Team,

I purchased a Microsoft 365 Business subscription directly from Microsoft and manage my organization's account.

I am unable to sign in because Microsoft Authenticator is not working, and no alternative verification method is available.

So wherever I wish to log in (e.g., to a new browser, it asks for Verification Code from Authenticator - so I try logging into this app and the Authenticator app itself asks for another V. code.)

My buisness account is ---> (VM Removed PII).onmicrosoft.com <---

I have tried contacting Microsoft Support by phone multiple times, but I cannot reach a human representative and AI chat bot just send links - not helping at all.

Could a Microsoft staff moderator please help me open a support case with the Data Protection / Tenant Recovery team?

Thank you for your assistance.

(EDIT: this is an open forum please don't post PII, thanks. )

Hello,

The AI-generated answer has not resolved my issue.

I have already tried Microsoft phone support, live chat, and the available self-service options. None of them allows me to reach a human support representative.

I am unable to access my Microsoft 365 admin center because of an Authenticator MFA loop. I need actual account recovery assistance, not another automated response.

Could a Microsoft staff moderator please review this thread and help initiate a Data Protection / Tenant Recovery support case?

I am willing to provide proof of ownership through a private, secure channel.

Thank you.

Hi Songyi Kim,

Have you tried the support on this page?

Sorry, no-one here at these forums can support that type of help.

Dear @Songyi Kim ,

Good day! Welcome to Microsoft Q&A forum!

First of all, I would like to clarify one point: as a forum moderator, I do not have the authority or the tools to assist you in resolving issues related to your tenant, account details, billing information, or authentication settings on your behalf.

Furthermore, current forum moderators do not have the authority to create tickets on your behalf. Tickets can only be created via calling or the Admin Center portal.

Based on your description, you are unable to sign in to your account because Microsoft Authenticator is not functioning.

First, could you please inform me if there are any other users with administrative privileges?

You can ask other administrators to follow the steps in this guide to revoke existing MFA sessions and require a new registration: Manage user authentication methods for Microsoft Entra multi-factor authentication. Usually, this process only takes a few minutes.

The next time you sign in, you'll be prompted to set up Microsoft Authenticator again from scratch.

Besides that, I sent you a private message. Would you mind checking it?

Any updates you’re able to share would be really helpful. I'm here and happy to help! Thank you for your kindness and patience!

Hello Daniel,

Thank you for your response.

Unfortunately, I am the only administrator of my Microsoft 365 Business account. There are no other administrators who can reset my MFA settings.

Therefore, I cannot follow the instructions you provided, as I cannot access the Microsoft 365 Admin Center at all.

I would really appreciate your guidance, as I have exhausted the available support options.

Thank you.

Dear @Songyi Kim ,

Thank you for your update.

1/ As an alternative, you can create a new trial tenant and submit your request from there.

To set up a new tenant, please follow these steps:

Visit Compare Office 365 Enterprise Pricing and Plans | Microsoft 365, choose any plan and click try for free to start a free trial.

Follow the guided setup process to create a new account for a new tenant.

Once your tenant is created, you should be able to access the support portal and submit your ticket referencing your locked account without further issues.

In the ticket's description, you could refer to this message

"Hello,

I am currently locked out of my tenant because multi-factor authentication is enforced, and I am unable to complete the verification process. I am the only global administrator for this tenant, which means I cannot access my account or the Microsoft 365 Admin Center.

To resolve this, I have created a new tenant and would like to be connected with the Data Protection Team to verify my identity and assist with regaining access. I am available to provide any required documentation or verification to support the recovery process."

Ticket Support: Log in the Microsoft 365 Admin Center using the newly created trial admin account (not the currently locked one) > Support > Help & Support. You can raise support ticket at: https://admin.microsoft.com/#/support/requests

When you open a support ticket, please make sure to turn off the Support Assistant (AI) in the help panel.

Several customers have reported issues when the Support Assistant is turned on the system sometimes fails to display the “Contact Support” option.

As shown in the screenshot, simply switch Support Assistant > Off, then type your issue description. Once the AI is off, the “Contact Support” button will appear normally, allowing you to submit a ticket directly.

After clicking on "Help & Support" button, you can type "I need agent support via phone or email". After that, you can click on "Contact support"

Choose contact method: "Phone"

Fill all the information in this contact support details, please describe your situation carefully so they will have enough information to help you.

Finally, click on "Contact me"

After completing them, you will receive an email appointment for a meeting to review this issue professionally together.

For more details, you could refer to this article: Get support for Microsoft 365 for business

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

2/ If you do not wish to create a trial tenant, please consider the following guidance for contacting Microsoft instead.

Please try to find the related hotline number to call the frontline let them raise a ticket for you: Technical or Sales support phone numbers (for Work account, scroll down to find your region's number)

In some countries, this is an automated conversation: First, when you call the hotline, they will ask you what kind of problem you are struggling with.

Answer: Authenticator.

A: What products do you use?

B: Office 365 for business.

Verification: Education or company account?

B: For companies

A: Are you an administrator?

B: Yes.

A: Are there any other administrators in your organization?

B: No.

A: I need one.... Service request?

B: Yes

(Important Note: Sometimes, you would hear the computer-generated voice at first, please kindly wait for it to end, and if an agent is available, you would be directed to them and get your support. Depending on your country or region, 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.)

Kindly let me know when there are updates or if you need further assistance. Thank you for your kindness and patience!
