Dear @Hakan BOR,
Good day! Welcome to Microsoft Q&A forum!
Based on your description, I understand that you're unable to access your work account in the Microsoft Authenticator app. When you try to sign in, the app generates a code and asks you to verify it within the same app, even though you can't open it. Additionally, there are no alternative verification options like phone or email. You mentioned that this account contains critical files, and you urgently need access.
I sincerely apologize for the inconvenience caused by this issue.
To understand the situation better and provide you with the most suitable support, could you confirm the following information:
- When you tried to open the Authenticator app, was there any error message?
- Have there been any new changes (new phone, app reinstalled, change of phone number, etc.)?
- Are you an end-user or an admin (if you are an admin, are you a Global admin or do you have a different role)?
Your confirmation would be very helpful in ensuring you receive the most suitable support!
Regarding your situation, if you're an end-user, please reach out to your IT administrator for assistance. If you’re unable to sign in due to a phone change, a new phone number, or issues receiving your authentication code, your IT administrator can help by updating your authentication methods or revoking and re-registering your authentication.
Please note that forum moderators have no control over user accounts, especially when it comes to logging in to your account, resetting your password, changing your access, etc.
For detailed guidance, ask your IT administrator to review the step-by-step instructions provided in the referenced article: Manage user authentication methods for Microsoft Entra multifactor authentication
Here's how to find your IT Admin: How do I find my Microsoft 365 admin? (please also kindly reach out to your colleagues, managers, etc. to see if they have the IT department contact)
If you're an admin, please check to see if there are other IT admins in your organization who can help you with the reset.
If you're the only admin, in this situation, the Microsoft Data Protection Team has tools and processes in place to verify identity and regain access to administrator accounts.
Please inform me if you're the only admin in your organization so that I could provide appropriate next steps accordingly.
Kindly let me know when there are updates or if you need further assistance. Any updates you’re able to share would be really helpful. I appreciate your time and look forward to hearing how things are going!
Thank you for your time and patience.
