Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
This is an MFA registration loop on a work or school account. The Authenticator entry shown as “Sign in to add your account” is not fully set up, so it cannot provide the code or approval needed to complete sign-in.
Try these steps in order:
- On the sign-in screen, select Sign in another way.
- If another method was already registered, use text message, phone call, or another available option.
- If one of those works, sign in and then update the account’s security methods.
- In Microsoft Authenticator, check whether the school account is already usable.
- Open the app and confirm it opens normally and the account is listed.
- If the app is locked, unlock it first.
- Make sure notifications are enabled for Authenticator.
- Update and refresh the app/device.
- Update Microsoft Authenticator to the latest version.
- Restart the phone.
- If using mobile data, try Wi‑Fi, and vice versa.
- Make sure Date & time on the phone are correct.
- If the account in Authenticator still says Sign in to add your account, the registration is incomplete.
- At that point, this usually cannot be fixed from the phone alone.
- The school IT help desk or Microsoft 365 admin needs to clear or reset the MFA registration so the account can be set up again.
- When contacting the school IT help desk, ask them to reset MFA / require re-registration of multifactor authentication for the school account.
- After they clear the old registration, the next sign-in should prompt a fresh Authenticator setup.
- Important: resetting MFA removes existing verification methods, so a new method must be set up at the next sign-in.
If repeated sign-in attempts were made, Microsoft Entra MFA can temporarily block more attempts. In that case, wait and try again later, or use a different registered MFA method if available.
If the app is still failing after the reset process starts, open Authenticator and use Send feedback from the app menu so logs can be captured for diagnostics.
