Not getting authenticator notifications. Can't sign into any of my work emails.

Follow these steps to restore Microsoft Authenticator notifications so work sign-ins can complete:

1. Check device notification settings
   • Open the phone’s Settings.
   • Ensure Do Not Disturb/Quiet mode is turned off.
   • Confirm push notifications are enabled for Microsoft Authenticator.
   • Make sure sound/vibrate is allowed if alerts are needed.
2. Verify other apps receive notifications
   • Check if notifications from other apps arrive normally.
   • If no apps receive notifications, troubleshoot the phone’s network connection (Wi‑Fi/mobile data) and, if needed, contact the mobile provider because the Android/Apple notification channel may be affected.
3. Fix “no notifications when app is closed” behavior
   • Ensure Authenticator is not restricted by battery optimization or background app limits (in phone Settings).
   • If notifications arrive only when the app is open, this usually indicates background or notification restrictions on the device.
4. Re-add problematic work account in Authenticator
   • If some accounts work but work email accounts do not:
     • Open Microsoft Authenticator.
     • Remove the problematic work account from the app.
     • Add the work account again and allow notifications when prompted.
5. Check time/date and app version
   • Set the device clock to automatic date and time, then restart the phone.
   • Make sure the latest version of Microsoft Authenticator is installed.
6. If still unable to sign in
   • For work/school accounts, contact the organization’s IT admin and ask them to help reset sign-in/MFA methods so the account can be re‑registered in Authenticator.

If an error such as “Enable push notifications to receive alerts” or “Please ensure push notifications are enabled in Settings” appears, it specifically means:

• Turn on push notifications for Authenticator in device Settings.
• Confirm the device has internet access.
• If the issue persists after removing and re‑adding the account, contact Support (for personal accounts) or IT admin (for work/school accounts).
