Can’t log into my university Microsoft account because of Authenticator app

Hi @Franciszek Dąbrowski, 

Thank you for posting your question in the Microsoft Q&A forum, and I’m sorry to hear you're having trouble accessing your university account. 

To better assist you, could you please clarify the following: Have you previously set up the Microsoft Authenticator app on any device for this account, or is this your first time trying to sign in? 

Additionally, when your university enforces multi-factor authentication (MFA) and only allows verification through the Microsoft Authenticator app, the system will not display other options such as SMS, email, or phone call unless those methods have been configured by your administrator. That’s likely why you're being prompted exclusively for the Authenticator app. 

If you haven’t installed the app yet, you can follow this official guide to get started: How to add your accounts to Microsoft Authenticator - Microsoft Support  

Please understand that our initial response may not resolve the issue immediately. However, with your help and more detailed information, we can work together to find a solution. 

If you have any updates, feel free to leave a comment under this post. I’ll be happy to assist further.
