How can I show Microsoft Authenticator app code

If the account is already in Microsoft Authenticator but no code appears, try these checks in order:

1. Open Microsoft Authenticator and tap the university account.
   • Look for a line such as One-time password code.
   • If Excel is asking for an approval request instead of a code, the app may require opening the account or responding to a sign-in prompt rather than showing a 6-digit code automatically.
2. If Excel shows a number-matching prompt, use the notification flow:
   • On the sign-in screen, select Send notification.
   • If needed, select Other ways to sign in > Approve a request on my Microsoft Authenticator app.
   • Open Authenticator or tap the New sign-in request notification.
   • If the app is locked, unlock it.
   • Enter or tap the matching number, then approve.
3. Refresh the app manually.
   • Open Authenticator and pull down to refresh. For anomalous or unfamiliar sign-ins, the notification might not arrive automatically and refreshing can surface the request.
4. Check common causes when authentication does not complete:
   • Make sure the app is unlocked.
   • Make sure notifications are enabled and not silent.
   • Update Microsoft Authenticator to the latest version.
   • Verify the phone has a working internet connection. Switching between Wi‑Fi and mobile data can help.
   • Make sure the device date and time are correct.
5. If Authenticator shows an error such as "Something went wrong. [4s8qz]":
   • Wait a few moments and try again.
   • Confirm the app opens normally and the account is listed.
   • Update the app.
   • Restart the device.
6. If the account was added but still cannot show a code or complete sign-in:
   • For a work or school account, admin policies can block registration or phone sign-in. If messages mention a restricted location or Conditional Access, the university administrator must enable the feature or reset the authentication method.
   • If no other sign-in methods are available, the university IT admin/helpdesk is the path to reconfigure or reset MFA for the account.
