#1 Force Stop the McDonald’s App

The McDonald’s app was released so that we don’t have to use a third-party platform to order our food. It also offers exclusive discounts.

But, I’m sure you’ll agree that sometimes instead of making our lives easier, it makes them more complicated.

Its performance issues can be super annoying and have caused controversy among customers. Some of them have even deleted the app and ordered their food from a different restaurant.

I bet you’re thinking of joining them, but before you do, please force-stop the app.

You see, bugs and glitches may be the reason the McDonald’s app keeps saying “Authentication Required”.

By fully closing the app, you may get rid of them and refresh any background process from scratch.

Follow this quick guide to do it:


  1. Go to Settings and select “Apps & Notifications”.
  2. Choose the McDonald’s app and tap on “Force Stop”.


  1. Swipe up from the bottom of your screen and pause in the middle.
  2. Swipe up on the McDonald’s app to close it.

If you have an iPhone 8 or SE, please double-click the home button to see the apps that are running in the back.

Force quit the McDonald's app

Once you’ve fully closed the app, relaunch it and try placing your order again.

#2 Check Your Email

If the McDonald’s app keeps saying “Authentication Required”, chances are your email hasn’t been verified.

Please check if you have received an email from McDonald’s. But, if you can’t find it, please check your junk and spam folders. Sometimes emails can automatically go to these folders.

If it is there, please mark it as “Not Spam”, verify your email address, and edit your “safe senders and domains” list to avoid this from happening again.

Verify your email on the McDonald's app

Tip: Please make sure you’re using the same device on which you’ve installed the McDonald’s app to verify your email.

But, if your email was already verified, and you keep getting the “Authentication Required” error, chances are there’s a problem with your account.

Don’t worry, though. Keep reading to learn how to solve it.

#3 Change Your Password

Moving on, I’d like you to change your password.

This quick action may force the app into recognizing that your account has been verified, and you may stop the McDonald’s app from saying “Authentication Required”.

Many users found that doing this solved the issue. Changing your password is really quick and simple, you’ll just need to:

  1. Launch the McDonald’s app and tap on “Did you forget your password?”. Then, you’ll be asked to enter your email.
  2. Go to your email and open the “Password recovery” email. Then, select “Continue”.
  3. Enter a new password (or choose the one that you previously had). Then, tap on “Change Password”.

#4 Sign Out and Back In

If changing your password didn’t do the trick, this just might.

Bugs can interfere with the way the McDonald’s app works and can cause problems in your account.

Sometimes by signing out and back into your account, you can get rid of any corrupted data that was causing the “Authentication Required” error.

To do it, you’ll need to:

  1. Go to the “More” tab at the bottom of your screen.
  2. Tap on your profile and select “Sign Out”.
  3. Enter your login credentials again.

Once you’ve logged in to your account again, please check if the “Authentication Required” error was solved.

#5 Clear Your Cache

You may not know this, but when you launched the McDonald’s app for the first time, it had to download tons of files, such as the menu images, scripts, and fonts, from its servers to display the page.

This data won’t change from visit to visit, so it’s convenient to store it somewhere where the app can access it quickly the next time you launch it, instead of having to load it again from its servers. This is where your cache comes in.

Your cache can make your McDonald’s app load much faster, but it may also be the reason it keeps saying “Authentication Required”.

You see, sometimes the files stored in your cache can become corrupted and may not match the version from the web, which can lead to experiencing login difficulties and different errors.

To solve these issues, I recommend clearing your app’s cache. Doing this may sound like a difficult thing to do, but it’s really simple. You’ll just need to:


  1. Please open the Settings menu and go to “Apps”.
  2. Tap on “Installed applications” and select the McDonald’s app.
  3. Go to “Storage” and choose “Clear cache”.

Please note that the process of clearing your cache may vary depending on your phone’s model.

If you have an iPhone, you’ll need to reinstall the McDonald’s app to get rid of the corrupted cache and data. Keep reading to learn how to do it.

#6 Reinstall the McDonald’s App

If none of the five fixes above have solved the issue, it’s time for us to reinstall the app.

I know, the whole point of installing the app for the first time is not having to repeat the process. But believe me, this is one of the most effective ways to restart every file within the app from scratch.

This way, you’ll be able to get rid of any corrupted data that didn’t go away by restarting the app, signing out and back into your account, and clearing your cache.

Follow these instructions to reinstall the McDonald’s and stop it from saying “Authentication Required”:


  1. Go to the home screen and press and hold the McDonald’s icon.
  2. Choose “Remove app” from the options.
  3. A message will pop up, please select “Delete app”.
  4. Go to the App Store and search for the McDonald’s app. Then, tap on the arrow icon to download it again.


  1. Go to the Google Play Store and tap on your profile icon.
  2. Tap on “Manage apps & device” and go to “Manage”.
  3. Choose McDonald’s app and select“Uninstall”.
  4. Go back to the Google Play Store and reinstall the McDonald’s app.

Once you’ve reinstalled the app, try signing in to your account and placing an order. The error should be solved.


Not being able to order your food because the McDonald’s app keeps saying “Authentication Required” can be super annoying.

But, I hope that this article has helped give you some more confidence in solving the issue.

If you take anything away, please let it be that the best way to get rid of the error is by force quitting the app, making sure your email is verified, and changing your password. Clearing your cache and reinstalling the app should also do the trick.
