Accessing Microsoft Teams for Education using school or organizational credentials
Dear @Polina Lupandina
Thank you for reaching out to Q&A forum.
I'm sorry to hear you're having trouble logging into your Microsoft account. I understand you're stuck in a frustrating loop where both Teams and the Authenticator app are asking for a code.
This issue often happens when your Multi-Factor Authentication (MFA) settings need to be reset, especially if you've changed devices or reinstalled the Authenticator app.
Since you are using a university email address, the MFA settings are managed by your university's IT department. You will need to contact them directly to resolve this.
Please contact your university's IT Help Desk or support team and explain the situation. You can say: "I am stuck in a login loop between Microsoft Teams and the Microsoft Authenticator app. I cannot get the code to sign in."
Specifically ask them to “Reset my MFA settings or allow me to re-register for MFA". This is a standard request, and your university’s IT team should be able to assist you with it.
Once your university's IT admin has reset your MFA, the next time you log in to your account, you will be guided through the process of setting up the Microsoft Authenticator app again from the beginning by scanning a QR code. This will break the loop and allow you to access your account normally.
We hope this helps you get back into your account quickly. Please let us know if you have any other questions.
