A cloud-based identity and access management service for securing user authentication and resource access
Dear @Kasper Richardt Tejlmand ,
Good day! Welcome to Microsoft Q&A forum!
First of all, I would like to clarify that this is a community forum where users help one another. No one here, including myself, has access to your Microsoft 365 tenant, account details, billing information, or authentication settings.
Regarding this situation, the error code 50089 generally occurs when the sign-in session expires or the authentication token becomes invalid before the verification process can be completed.
To better understand the situation, could you please confirm the following:
- Is this a work/school account or a personal Microsoft account?
- Do you still have access to your old phone where Microsoft Authenticator was previously configured?
- When you attempt to sign in, do you receive the verification code by SMS/email, or is no code received at all?
If you still have access to the old phone, try approving the sign-in request or removing and re-registering the Authenticator app after successfully signing in.
If this is a personal account, kindly let me know so I can provide you with appropriate steps.
If this is a work or school account with no alternative sign-in methods available and 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.
For detailed guidance, ask your IT administrator to review the step-by-step instructions provided in the referenced article: Manage user authentication options
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 let me know if you're the only admin of your organization so that I could provide you with suitable steps accordingly.
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!
