How to Fix Microsoft Authenticator App Not Working

The Microsoft Authenticator app is an essential tool for users who want to add an extra layer of security to their Microsoft accounts. However, like any other app, it can occasionally encounter issues that prevent it from working properly. In this blog post, we will explore some common solutions that can help you fix the Microsoft Authenticator app when it's not working as expected.

Force Close and Reopen the App

One of the simplest and most effective methods to resolve app-related issues is to force close and reopen it. The steps to force close an app vary slightly depending on the device you are using. However, the general process involves swiping up from the bottom of the screen (on iPhones without a home button) or double-tapping the home button (on iPhones with a home button) to access the app switcher. Then, swipe left or right to locate the Microsoft Authenticator app and swipe it off the screen to close it. Afterward, tap the app icon to reopen it.

Enable Automatic Date and Time

The Microsoft Authenticator app relies on accurate date and time settings to function correctly. If your device's date and time are set manually, it can cause synchronization issues and prevent the app from working properly. To enable automatic date and time on an iPhone, go to Settings > General > Date & Time and toggle on the "Set Automatically" option. On Android devices, the steps may vary depending on the manufacturer, but you can typically find the automatic date and time setting under Settings > System > Date & time.

Turn Off Battery Optimization for the App

Battery optimization settings on certain devices can sometimes interfere with the performance of the Microsoft Authenticator app. When battery optimization is enabled, it restricts background activities, which may prevent the app from functioning properly. To turn off battery optimization for the app, navigate to your device's settings and search for "Battery optimization" or "Battery usage." Locate the Microsoft Authenticator app and select "Don't optimize" or a similar option to exclude it from battery optimization.

Remove and Re-add Your Accounts

If the Microsoft Authenticator app is still not working correctly, you can try removing and re-adding your accounts. This action can help refresh the app's settings and resolve any underlying issues. To remove an account, open the app and go to Settings > Accounts. Select the account you want to remove and tap the "Remove account" option. To re-add the account, tap the "Add account" option and follow the prompts to set it up again.

Clear App Cache

App cache can accumulate over time and potentially lead to performance issues with the Microsoft Authenticator app. Clearing the app cache can help resolve these issues. On an iPhone, go to Settings > General > iPhone Storage, scroll down to find the Microsoft Authenticator app, and tap on it. Then, select the "Offload App" option to clear the cache. On Android devices, go to Settings > Apps > Microsoft Authenticator, and tap on the "Storage" option. From there, you can choose to clear the app cache.

Update the App

Keeping the Microsoft Authenticator app up to date is crucial for ensuring its compatibility with the latest security protocols and bug fixes. To update the app on an iPhone, open the App Store, go to the "Updates" tab, and tap the "Update" button next to the Microsoft Authenticator app. On Android devices, open the Google Play Store, tap the menu icon (usually three horizontal lines), select "My apps & games," and then tap the "Update" button next to the Microsoft Authenticator app.

Check App Permissions

App permissions allow the Microsoft Authenticator app to access necessary resources on your device. If certain permissions are disabled, it can cause the app to malfunction. To check app permissions on an iPhone, go to Settings > Microsoft Authenticator and ensure that all necessary permissions, such as camera, notifications, and location, are enabled. On Android devices, go to Settings > Apps > Microsoft Authenticator > Permissions and verify that the required permissions are enabled.

Reset App Settings

Resetting the Microsoft Authenticator app settings can be a last resort if none of the previous steps have resolved the issue. This action will restore the app to its default settings, which can help eliminate any software glitches. To reset the app settings on an iPhone, go to Settings > General > Reset > Reset All Settings. On Android devices, go to Settings > Apps > Microsoft Authenticator > Storage > Clear data.

Check Internet Connectivity

A stable internet connection is crucial for the Microsoft Authenticator app to function properly. If you are experiencing issues with the app, it's essential to check your internet connectivity. Ensure that you have a strong Wi-Fi or cellular network connection. You can also try switching between Wi-Fi and mobile data to see if the issue persists.
