How to Fix Instagram Two-Factor Authentication not Working

1. Check the Internet Connection

Internet connection plays a vital role while using Instagram. If you don’t have an internet connection you won’t be able to access the app or view its content at all. If you have an unstable intent connection then you need to make it stable.

What you can do is, if you are using a router then you can reboot the router and connect it again and try to check if it’s working or not. If you are using mobile data then what you can do is go ahead and turn it off and on again, try opening Instagram to check whether the problem has been fixed.

Though the authenticator app or Apple passwords don’t need an internet connection to generate a new code, you will need an active internet connection for logging in.

2. Enter the fresh code

If you are using a 2FA app like Google Authenticator, you must know that the 2FA app keeps generating fresh code after a few seconds. And the code is valid only till the time a new code is generated.

And in case, you are entering an expired code, you won’t be able to log in as intended. The expiration limit for a code is 30 seconds in most of the apps, even in ‘Apple Passwords’. That means, if you enter a code after the 30 seconds time window, you won’t be able to log in.

3. Enter the correct code

It is required for the user to enter the correct code for a successful login. The authentication app code is a 6-digit numerical code that you are going to find in your Authenticator app.

Sometimes, you might enter a code for a different app’s authentication. As you can add multiple apps and their login authentication in the same app, you might mistakenly add a different app’s authentication code.

It is always recommended to add a unique name for each setup key.

  • Step 1: Open Google Chrome on your device.
  • Step 2: Locate Incognito mode and tap on it.
  • Step 3: Search Instagram.
  • Step 4: Fill in your credential to log in. Then with the two-factor authentication, the code will be sent to your email or phone number.
  • Step 5: Fill in the code.

5. Clear cache and update the app

At times the corrupted files of the app can lead the app to become faulty and that could be one of the reasons why the authentication is not working you can proceed by clearing the app cache on your device and then updating the app.

  • Step 1: Locate settings on your device.
  • Step 2: Navigate to apps and locate the Instagram app.

6. Check your spam folder in the Message & Email folder

You might have received the two-factor authentication code, but the notification wasn’t displayed nor is it in your inbox, and you think the issue is with it not working.

You can open iMessage or any messaging app that you are using, and check the inbox, if it’s not in the inbox then head to the spam folder, you will find the email from Instagram where the authentication code is.

Even if you are entering a correct authentication code while logging into your Instagram app, you still might have trouble logging in.
