Issue with my Authenticator app

Common causes are:

1. Authenticator is locked Open Microsoft Authenticator directly and make sure the app is unlocked. If the app is locked, the code entry or approval prompt may not appear.
2. Notifications are disabled or silent On iPhone, check that Authenticator notifications are enabled. Silent or disabled notifications can prevent the sign-in prompt from appearing. Also check whether a texted authentication code arrived silently.
3. The app is outdated Install the latest version of Microsoft Authenticator.
4. Network problems Make sure the iPhone has internet access. Switching between Wi‑Fi and mobile data can help.
5. Date and time are incorrect On iPhone, go to Settings > General > Date & Time and make sure automatic time is enabled. Incorrect device time can affect code generation and sign-in.
6. The account may no longer be properly registered in Authenticator If the app was reinstalled and the account was not restored, it may show no usable codes or prompts. In that case, use another sign-in method if available.
7. For number-match prompts, open the app manually If sign-in shows a two-digit number, open Microsoft Authenticator manually, refresh it, and look for the prompt there. For some anomalous sign-ins, the notification is not pushed automatically; opening the app and pulling down to refresh can surface the approval request.
8. If this is a personal Microsoft account and email codes are not arriving Check junk mail, confirm the email or phone shown is correct, avoid repeated code requests, and note that codes can be delayed or temporarily blocked due to unusual activity. Valid email verification codes come from @accountprotection.microsoft.com.

If none of those work, use another verification method if one is available, or use the sign-in helper. Support cannot send verification codes or change account details for security reasons.
