Hi there, my account on my Authenticator app says that there is an error and I need to sign into my account. Then when I try and sign into my account it says I need an Authenticator code but I’m literally logging in on the Authenticator app with the app not downloaded on any other devices.

    This is usually a sign-in loop: the account is configured to require Microsoft Authenticator, but the currently registered Authenticator instance is no longer available or usable on the device.

    Try these checks first:

    1. Make sure the Authenticator app is unlocked.
      • If the app is locked, the entry box may not appear and authentication can fail.
    2. Make sure notifications are enabled for Microsoft Authenticator.
      • Silent or disabled notifications can prevent the prompt from completing.
      • Also check for any text-message authentication codes that may have arrived silently.
    3. Update Microsoft Authenticator.
      • Older app versions can cause sign-in problems.
      • Microsoft does not support app versions more than 12 months old.
    4. Check connectivity.
      • Switch between Wi‑Fi and mobile data.
      • Make sure Airplane mode is off.
      • If using VPN, disconnect it and test again.
    5. Check device settings.
      • Make sure the device date and time are correct.
      • Make sure the device OS is up to date.
    6. If the app shows a temporary error such as "Something went wrong. [4s8qz]":
      • Wait a moment and try again.
      • Open Authenticator and confirm it launches normally and the account is listed.
      • Restart the device.

    If the account is a work or school account and no other verification method is available, the next step is to contact the organization’s IT admin or helpdesk. They can investigate the Microsoft Entra sign-in logs, and if needed, help reset the MFA setup so Authenticator can be registered again.

    If the account is a personal account, send logs from Authenticator by opening the app menu and selecting Send feedback, then contact Support.
