Authenticator uygulamasına giremiyorum

Hello REGE KAAN KOLAÇ

Thank you for posting in the community.  

Based on the details you provided, it appears that you're unable to log into your school portal account because your phone, which had the Microsoft Authenticator app installed, is no longer accessible.

Since you are using a student account, it's best to reach out to your institution's IT support team for direct assistance. Our community team does not have the necessary permissions or tools to access user information. Also, Microsoft does not manage these accounts and cannot adjust user settings without the organization's approval. Your IT support team will be able to investigate your account setup and help resolve the issue.

Be ready to provide any information they might request for identity verification, including your full name, student ID, email address associated with the account, and any other relevant details.

Your IT administrator will implement the steps outlined in the article to help you remove the old device from your authentication method. Once this is done, you should be able to receive the approval codes on your new phone and regain access to your account.
