    Try these checks on the iPhone, in this order:

    1. Update Microsoft Authenticator Open the App Store and install the latest version. Microsoft does not support Authenticator versions more than 12 months old.
    2. Check basic phone conditions
      • Turn off Airplane mode.
      • Switch between Wi-Fi and mobile data.
      • If a VPN is enabled, disconnect it and test again.
      • Make sure Date & Time on the iPhone are correct.
    3. Check Authenticator notification settings In Authenticator, open Settings and make sure notifications are enabled. If the phone is in Do Not Disturb or Quiet mode, notifications may be blocked.
    4. If authentication says it did not complete
      • Make sure the Authenticator app is unlocked.
      • Check whether notifications are silent or disabled.
      • Look for authentication codes that may have arrived silently.
    5. If the issue started after reinstalling the app or moving to a new iPhone Reinstalling Authenticator does not automatically restore account registrations unless backup was enabled and restored. If the account is missing or not working after a phone change, the old registration may no longer be available on the new installation.
    6. If backup restore is not appearing on a new iPhone On the old iPhone:
      • Enable iCloud Drive.
      • Enable iCloud Keychain.
      • Enable iCloud Backup.
      • In Saved to iCloud, search for Authenticator and turn it on.
      • Make sure Authenticator is version 6.8.33 or later.
      • Open the app at least once before switching phones.
      On the new iPhone:
      • Uninstall and reinstall Authenticator.
      • The backup should then appear.
    7. If notifications still do not arrive If some accounts notify and others do not, remove the affected account from Authenticator, add it again, and allow notifications.
    8. If nothing works
      • For a personal account, send logs from Authenticator: open the app menu and select Send feedback, then contact Support.
      • For a work or school account, contact the IT admin. If the app was reinstalled and the account registration is gone, an MFA reset may be required.
