Hi @Tushar Bihan,

I’m really sorry that you’re running into this issue.

From what you’ve described, this does look like an MFA loop issue. It usually happens when the Authenticator app session gets out of sync, so it asks you to sign in again but still requires a code that it’s no longer generating.

In this situation, the best course of action is to contact your school IT administrator. They have the ability to reset your multi-factor authentication (MFA) settings, which will allow you to sign in again properly.

You can kindly ask them to follow the steps in this guide to revoke your existing MFA sessions and require re-registration: Manage authentication methods for Microsoft Entra multifactor authentication - Microsoft Entra ID |…

This process only takes a few minutes. It will clear out your previous sign-in sessions, and the next time you sign in, you’ll be prompted to set up MFA again from scratch on your phone. That usually resolves the issue and allows the Authenticator app to start generating codes normally again.

As this is a user-to-user support forum, I can only offer steps based on my experience and how similar cases are typically resolved, rather than making direct changes. In your case, the account is entirely managed by your school, and only those with the appropriate administrative permissions can modify its security settings.

That said, I sincerely hope this information will help direct you to the correct support team so you can regain access to your account as soon as possible and continue your studies without further interruption.

Thank you again for your time and understanding.

    Because the university account is a work/school (Microsoft Entra / Azure AD) account protected by MFA, the loop happens when Authenticator was removed or lost and there is no other verification method available.

    Use these steps depending on what is still accessible:

    1. Check for any alternative MFA method
      • Start signing in to the university account as usual.
      • On the MFA prompt, look for an option like “Sign in another way”.
      • If it appears, select another method (SMS, call, backup email, office phone, security key) and complete sign-in.
      • After signing in, go to your Security info / Advanced security options page and add a new method (e.g., re‑register Microsoft Authenticator, add phone, etc.), then remove the old/broken method.
    2. If there is no alternative method and only Authenticator was configured
      • For a university/work account, only the organization’s IT/Help Desk (tenant admins) can reset MFA.
      • Contact the university IT support and ask them to clear/reset your MFA settings or require re‑register multifactor authentication for your account in Microsoft Entra.
      • After they reset it, sign in again; you will be prompted to set up Authenticator (scan QR code) or another MFA method from scratch.
    3. If you see repeated sign‑in failures or blocks
      • Too many failed attempts can cause temporary blocks on MFA or sign‑in. If you have tried many times, wait before retrying and avoid repeated attempts that can extend the block.

    Without an alternative MFA method or admin reset, access cannot be restored, because Microsoft cannot bypass 2FA for security reasons.
