How to Fix Microsoft Authenticator App Not Working
There are a number of proven tech tips that can prevent the Microsoft Authenticator app from stopping, freezing, and crashing.
1. Check if Microsoft Authenticator app’s down. The Microsoft Authenticator service could be experiencing a server outage or other technical issue.
2. Close the app, and then reopen it. This is the easiest solution that will work in some cases if it’s just a temporary problem. To do this, you’ll need to close the Microsoft Authenticator app on your Android or close the Microsoft Authenticator app on your iPhone. Then, relaunch the app to see if the problem is finally resolved.
3. Check your phone’s internet connection. The quickest way to do this is to open another app that needs an internet connection.
If your Wi-Fi is slow or completely down, turn it off and try using your phone’s cellular connection to access Microsoft Authenticator app. If your Mobile data is slow or completely down, turn it off and try using your Wi-Fi to access Microsoft Authenticator app.

4. Restart your device. Restarting your mobile device will often clear most problems. So take a moment to reboot your Android or reboot your iOS device to see if it resolves problems with Microsoft Authenticator app not working.
Note: Why does a restart often help? When you restart your device, it clears out all the temporary files and working memory and loads up all the information the device and app(s) need. Sometimes these files have become temporarily corrupted and the only way to clear the corruption is with a restart.
5. Check for Microsoft Authenticator app updates. Check for and install any Microsoft Authenticator app updates on your Android device or app updates on your iPhone. If your Microsoft Authenticator app is ever out of date, it can lead to connection errors and other issues that may lead to Microsoft Authenticator not working on your mobile device.
6. Clear the Microsoft Authenticator app cache on your Android device or clear the cache on an iPhone. While caching improves app performance by saving app information in local memory, it can also lead to issues with your device not receiving the latest information from Microsoft Authenticator. Clearing cached data will force your app to retrieve the latest information from Microsoft Authenticator.
7. Check the Microsoft Authenticator app permissions. You need to give Microsoft Authenticator permission to access things like your contacts, photos, mic, etc., otherwise, those things won’t work.
8. Uninstall and reinstall the Microsoft Authenticator app. If nothing else has worked to this point, take the time to completely uninstall Microsoft Authenticator from your Android or iPhone. Then reinstall the Microsoft Authenticator app on your device.
9. Free-up space on your phone. A lack of free space can often cause apps to crash or not open.
10. Disable your VPN service. A VPN is a great service for protecting your privacy and increasing security. Unfortunately, a VPN can also cause connection errors and lead to Microsoft Authenticator not working. To test if this is the case, disable your VPN on Android device or disable your VPN on iPhone and check if this resolved the issue.
11. Make sure background data is not restricted. If Background data is turned off, Microsoft Authenticator may not be able to connect to the internet while it’s running in the background. To fix this, you need to turn on the background data on Android or turn on the background data on iPhone.
12. Reset your iPhone’s app settings or reset app settings on your Android device. This action does not delete any of your apps or their data. It reverts app-specific settings back to their default values. This can include preferences like notification settings, permissions, background app refresh settings, and other app-specific configurations.
13. Reset your phone’s network settings. If the Microsoft Authenticator app is having trouble connecting to the Microsoft Authenticator servers, performing a network settings reset on your Android device or network settings reset on your iPhone could fix it.
15. If all else fails, it may be time to report the issue to Microsoft Authenticator. It could be an issue with your account, and Microsoft Authenticator customer support should be able to help you determine if that’s the case.
If Microsoft Authenticator notifications aren’t working, ensure you’ve enabled notifications in your iOS or Android device settings. Next, go to your Microsoft Authenticator account and select the notifications you want to receive. Also, ensure your phone isn’t set to Do Not Disturb, and clear the Microsoft Authenticator data cache.
