How to Fix Microsoft Authenticator App Not Working
1. Check Your Internet Connection
A poor internet connection is one of the common reasons why the Microsoft Authenticator app not working properly. The app needs internet access to receive push notifications and approve certain sign-in requests. Check whether your Wi-Fi or mobile data is working correctly. If the connection is unstable, switch to another network and try signing in again.
2. Restart the Microsoft Authenticator App
If you are facing the Microsoft Authenticator app not working issue, restarting the application is one of the easiest solutions to try. Sometimes, temporary glitches prevent the app from processing authentication requests. Close Microsoft Authenticator completely, wait a few seconds, and open it again. If the problem continues, restart your smartphone.
3. Update Microsoft Authenticator
An outdated application can cause compatibility issues, missing notifications, and verification errors. If your Microsoft Authenticator app is not working, check whether a newer version is available. Open the Google Play Store or Apple App Store, search for Microsoft Authenticator, and tap Update if available. Once updated, reopen the application and try again.
4. Enable Notification Permissions
Are you facing the Microsoft Authenticator not sending notifications problem? Your phone’s notification settings might be blocking authentication requests. Enabling the required permissions can help restore incoming notifications.
Steps to follow:
- Open your phone’s Settings.
- Go to Apps and select Microsoft Authenticator.
- Tap Notifications.
- Enable Allow Notifications.
- Check whether Do Not Disturb or Focus Mode is blocking alerts.
5. Set Date and Time to Automatic
Incorrect date and time settings can be another reason behind the Microsoft Authenticator verification code not working issue. The app uses accurate time synchronization for generating time-based verification codes. If your codes are not working, check your smartphone’s date and time settings and enable automatic synchronization.
Steps to follow:
- Open your phone’s Settings.
- Navigate to Date and Time.
- Enable Automatic Date and Time.
- Turn on Automatic Time Zone if available.
- Try generating a new verification code.
6. Clear Microsoft Authenticator Cache
If the Microsoft Authenticator app is not working on Android, corrupted temporary files may be responsible. Clearing the app cache can help resolve minor performance issues without normally deleting saved account information. Open Settings, navigate to Apps, select Microsoft Authenticator, and choose Clear Cache under Storage.
Note: Avoid selecting Clear Data because it may remove locally stored account information.
7. Check Battery Optimization Settings
Battery-saving features can restrict background activity and prevent Microsoft Authenticator notifications from arriving on time. If you are experiencing the Microsoft Authenticator notification not working issue, review your phone’s battery settings. Allow background activity for the app and remove restrictive battery optimization settings where available.
8. Verify Your Account Configuration
Incorrect account registration can cause the Microsoft Authenticator login not working problem. Open the application and check whether your account appears correctly. If you recently changed your phone, you may need to restore your backup or register the new device again. For work or school accounts, contact your IT administrator if necessary.

10. Reinstall Microsoft Authenticator
If you are still facing the issue with the Microsoft Authenticator app not working, then you can try reinstalling the application. However, before you remove it from your device, ensure that you have an alternative sign-in method to your account and ways to recover it.

However, there are some simple solutions you can try first, such as updating the app, turning on notifications, checking your connection and making sure your phone is set up correctly.
