Hello @Sven Bezemer,
Thank you for posting your valuable question on Microsoft Q&A forum.
Based on your description, I understand that you recently switched to a new phone and are trying to access your university email, which requires Microsoft Authenticator. When you sign in, you’re asked for a code, but the Authenticator app on your new phone isn’t set up yet. The notification still goes to your old phone, and even when you enter the code from there, the sign‑in does not complete.
Please let me know if I misunderstood any part of your issue or if there are additional details you’d like to share.
If you still have the old phone, you can try these steps:
Use Cloud back up:
- Open the Microsoft Authenticator app on your old phone.
- Go to Settings > Backup and ensure cloud backup is enabled (linked to your Microsoft account).
- On your new phone, install Microsoft Authenticator and sign in with the same Microsoft account to restore the backup.
- Verify that your accounts appear and test login.
Add Authenticator from a computer
- Go to: https://mysignins.microsoft.com/security-info
- Sign in to your work or school account using multi‑factor authentication on your old phone.
- Click + Add sign-in method
- Select Microsoft Authenticator > Click Next > A QR code will appear on your screen
- Open Microsoft Authenticator on your new phone
- Tap + (Add account) > Choose Work or school account
- Select Scan a QR code > Scan the QR code shown on your computer
- Microsoft will send a test notification, approve it in the app to finish setup.
If the steps above don’t fix the problem, could you please confirm that you are the end-user or the IT admin of your organization?
If you are the end-user, I would recommend you contact your organization account's Admin to reset your MFA settings through the Microsoft Entra Admin Center.
If you haven’t yet reached out, here’s a helpful guide to locate your Microsoft 365 administrator: How do I find my Microsoft 365 admin? - Microsoft Support
Here are some key points to keep in mind:
You start by contacting the person who originally provided your account, such as a teacher, school administrator, or IT support staff. They can verify permissions, confirm your group membership, and check for restrictions. If unsure who to reach out to, begin with a teacher or staff member you regularly interact with; they can assist or direct you to the right department. Additionally, use your school’s helpdesk portal, support email, or tech support channel for assistance.
Ask your administrator to follow these steps:
- Go to Microsoft Entra Admin Center: https://entra.microsoft.com
- Navigate to Users > All Users.
- Select your user account.
- Go to Authentication Methods.
- Click "Require re-register multifactor authentication".
This will reset your MFA settings. The next time you sign in, you’ll be prompted to set up the Authenticator app again using a QR code.
If you're an IT admin, please check to see if there are other IT admins in your organization who can help you with the reset.
If you are the only administrator in your organization, this request cannot be handled through the Microsoft Q&A forum due to security and privacy limitations. In this case, you will need to contact the Microsoft Data Protection team, as they are the only group authorized and equipped with the necessary tools and verification procedures to confirm your identity and restore administrator access.
Please try to find the related hotline number to call the frontline and let them raise a ticket for you: Customer service phone numbers - Microsoft Support
Please carefully follow this instruction to ask for Microsoft Data Protection team support:
Depending on your country or region. For some countries, when calling the support number, although there are about 30 seconds opening as something "you can visit the link...." But you can ignore this opening and wait until the option, then "1" as a business email user, "1" again for technical help.
For some countries, it will be an automated conversation like:
First, when you call the hotline, it asks what kind of problem you are worried about.
Answered: authenticator.
A: What kind of product are you using?
B: Office 365 for business.
A confirmation: education or company account?
B: For companies
A: Are you an administrator?
B: Yes.
A: Do you have the other admin in your organization?
B: No.
A: You need one.... Service request?
B: Yes
If your organization's Office 365 Business/Education subscription is from a partner or reseller, and the global administrator is unable to open a service request on your end, contact the reseller's support provider to help open a service request on behalf of you instead.

I hope Data Protection team can successfully revoke your access. If you need any further assistance or need help on any process, please feel free to reply. I'm here to help!
