What is Microsoft Authenticator App?

You’re probably familiar with the Microsoft Authenticator app for generating two-factor authentication codes on your phone. It’s an incredibly useful tool that helps to keep your accounts secure and accessible only to you.

As a result, it’s no surprise that many people rely on this app for their everyday needs. However, sometimes the Microsoft Authenticator may not work as expected—here are three reasons why:

  1. Improper setup: The app may have been installed incorrectly or configured improperly.
  2. Incorrect device clock: The time settings of the device could be inaccurate, which affects how the application works.
  3. Other factors: There could be other underlying issues that interfere with the functioning of the app such as conflicts between other applications or network connectivity problems.

This brings us to our next topic—why is my Microsoft Authenticator App not working? Let’s take a look at some common reasons behind this issue…

Why Is My Microsoft Authenticator App Not Working – Common Reasons:

We’re here to discuss why your Microsoft Authenticator app might not be working.

Common reasons are:

  • An unstable internet connection
  • Outdated version of the app
  • Insufficient phone storage
  • Cache issues
  • Bugs and glitches

So let’s identify which one of these is causing the issue with your Authenticator app and get it back up and running in no time!

Unstable Internet Connection

If your internet connection is unstable, it can cause problems with Microsoft Authenticator. Unreliable connections won’t be able to access the data that the app needs to function efficiently. This means that all of your sign-ins, notifications, and security codes will not work properly.

That’s why it’s important to make sure you have a strong, stable internet connection at all times. Otherwise, you could find yourself locked out of accounts or unable to send messages securely.

To ensure that this doesn’t happen, try using a different Wi-Fi network or switching off your cellular data for a few seconds and then switch back on again. Once done, check if the issue has been resolved.

If not, then perhaps you may need to look into updating the version of the Microsoft Authenticator app installed on your device.

Outdated Version of App

If you’re using an outdated version of the app, it could be causing problems with your device. Outdated apps aren’t able to offer a smooth user experience and may not be compatible with the latest system requirements. If your Microsoft Authenticator app is out of date, it could lead to bugs or glitches that prevent it from working correctly.

To avoid this issue, make sure that you’re always running the latest version of the app on both iOS and Android devices. This can often be done through automatic updates if enabled in your device’s settings menu. Additionally, checking for updates manually from time to time can help ensure that you have the best user experience possible.

Now onto insufficient phone storage…

Insufficient Storage on your Phone

You may be running out of storage on your phone, which can cause problems with the performance of your device. Insufficient phone storage can lead to poor app loading and response times, inability to download new or update existing apps, and the overall slowdown of the phone’s operating system.

As a result, users may experience an issue where their Microsoft Authenticator app no longer works as intended. To help prevent this from happening, it’s important to manage your mobile device’s available storage space regularly by deleting unnecessary files and backing up data elsewhere if possible.

Moving forward, we will consider another potential issue that could be causing the problem – cache issues.

An Issue with the Cache

Caching can cause performance issues if it’s overcrowded. Cache data become outdated over time and too much of it may slow down your device and the app you are trying to use.

To fix this issue, you should clear the cache for your Microsoft Authenticator App by going into its settings and selecting ‘Clear Cache’. You may also want to check for any updates or bug fixes available for the app as these could be causing further issues. Doing this will help make sure that the app is running smoothly without any cache-related hiccups.

After this, you’ll be ready to move on to identifying potential bugs & glitches.

Fix Microsoft Authenticator App Errors on Android / iPhone

We are here to discuss how to fix Microsoft Authenticator App errors on Android and iPhone.

To do this, we need to make sure our internet connection is on, force-stop the app and relaunch it, clear the app cache and data, remove and re-add our accounts in Microsoft Authenticator, and update the app to the latest version.

All of these steps should help us get back up and running with no further issues.

Make Sure Your Internet Connection Is On

Check that your internet connection is on and stable so you can use the Microsoft Authenticator app. Make sure to have a strong signal, with no interruptions or hiccups in service. Double-check that any firewall or security settings are not blocking your connection. Review your data plan for any restrictions or limits.

If all of these items look good, then you should be able to start using the app again. Next, force-stop the app and relaunch it to see if this resolves the issue.

Force-Stop App & Start it again

To resolve the issue, force-stop the app and restart it.

On Android devices, press and hold on the app’s icon then select the ‘i’ icon to pull up a menu.

Tap ‘Force Stop’ at the bottom-right corner to close the application.

For iPhones, swipe up from the bottom of your screen and locate the Microsoft Authenticator card in the app switcher. Swipe it upwards to close it.

Clearing the cache and data may help resolve any issues you’re having with the Microsoft Authenticator app.

To do this on an Android device, long-press the app icon and tap the info icon in the pop-up menu. Then go to Storage and select ‘Clear cache.’

Note that doing so will not delete any of your accounts. So if you’ve been experiencing unexpected behavior with the Authenticator, give this a try before moving on to other measures.

Next up: removing and re-adding your accounts in Microsoft Authenticator.

Remove and Re-Add Your Accounts in Microsoft Authenticator

If your accounts are not behaving as expected, try refreshing them by removing and re-adding them in the Authenticator.

To do this, open Microsoft Authenticator on your phone and select the account you want to remove. Tap the gear icon at the top-right corner and choose ‘Remove Account’ on the following page.

To add an account back in, select the + (plus) sign at the top of the screen and access your online account from a desktop’s web browser to find its QR code. Point your phone’s camera toward it and it will be added into Microsoft Authenticator.

This should resolve any minor issues with these accounts.

Next, update your app to ensure you have all the latest features and bug fixes to make sure everything works properly.

By doing this, you can make sure that you have access to all of the latest features and bug fixes, allowing for a better user experience with Microsoft Authenticator.


Additionally, updating your phone’s operating system may also help resolve any issues related to the application not working properly; more on that below.

Check And Install Your Android / iOS Phone Updates

Keeping your phone’s operating system up-to-date is just as important as updating apps, so make sure to check for and install any available updates. For Android users, go to Settings > System and tap on “System Update”. For iPhone users, go to Settings > General > Software Update and turn on the “Download iOS Updates” and “Install iOS Updates”.

Updating your phone is key in keeping you connected with the latest features without compromising security or stability. Doing so will ensure a more enjoyable experience overall. With that in mind, let’s look at how to uninstall & reinstall the app…
