I can't log into MS account on iPhone

Check the following on the iPhone 15 to get Microsoft Authenticator notifications so the two-digit code prompt can be approved:

1. Make sure the Authenticator app is unlocked
   • Open Microsoft Authenticator on the iPhone.
   • If it asks for Face ID/Touch ID or a PIN, complete that so the app is fully open. If the app is locked, the approval box may not appear.
2. Enable notifications for Authenticator
   • On the iPhone, go to Settings → Notifications → Authenticator.
   • Turn on Allow Notifications and enable Lock Screen, Notification Center, and Banners.
   • Ensure Sounds and/or Badges are enabled so prompts are noticeable.
3. Check for silent or blocked notifications
   • Make sure Do Not Disturb / Focus modes are off or configured to allow Authenticator notifications.
   • Confirm other apps can receive notifications; if none can, there may be a broader notification or network issue.
4. Verify network connectivity
   • Ensure the iPhone has internet access (Wi‑Fi or mobile data).
   • If prompts still don’t appear, switch between Wi‑Fi and mobile data and try signing in again.
5. Update Microsoft Authenticator
   • Open the App Store and confirm Microsoft Authenticator is updated to the latest version. Outdated versions can cause sign-in issues.
6. Check device date and time
   • Go to Settings → General → Date & Time.
   • Turn on Set Automatically so the time is correct; incorrect time can cause authentication failures.
7. Use an alternate verification method if available
   • On the sign-in screen, choose Sign in another way (or similar) and select text message, phone call, or code from the app if those methods are configured.
   • For code-based sign-in, open Authenticator, tap the account, and enter the code shown into the Enter code box on the sign-in page.

If none of these steps restore the notification, use the Sign-in helper or Contact Support options from Microsoft’s account help pages to get further assistance, as support agents cannot send verification codes or change security info directly.
