Facebook authentication errors are frustrating, but they're usually fixable! Here's how to diagnose and resolve the most common causes.
What causes authentication errors:
Credential mismatch - An "Authentication Failed" error occurs with Facebook login when the credentials of your game account and the credentials of your Facebook account don't match
Common causes:
Multiple Facebook accounts - Being logged in to multiple Facebook accounts
Account type changes - Updating your Facebook to a professional/monetized/creator account
Email changes - Recently changed your Facebook email
Wrong login method - Previously logged into the game using Google login instead
Step-by-step solutions:
If you recently changed your Facebook email:
- Open the Facebook settings
- Revert to your previous Facebook account email
- Log in to Atlas Earth
If you updated to a professional/creator account:
- Open the Facebook settings
- Revert to your previous Facebook account status
- Log in to Atlas Earth
If you've been using multiple Facebook accounts:
- Log out of the game (you may need to uninstall and reinstall the app to force a log out)
- Sign out of all instances of Facebook in your browser
- Uninstall the Facebook app if you have it installed
- Clear your cache and browser history
- Log back in using the correct Facebook account
If you originally used Google login:
- Click the "Other Options" button at the bottom of the login screen
- Select the Google login option
- Log in using your Google login
Additional troubleshooting:
Quick fixes to try first:
Restart the app - Force close and reopen Atlas Earth
Update Facebook app - Ensure you're using the latest version
Check internet connection - Verify you have stable connectivity
Verify Facebook login - Make sure you can log into Facebook normally
Prevention tips:
Stick to one login method - Don't switch between Facebook and Google
Avoid email changes - Keep your Facebook email consistent
Single Facebook account - Use the same Facebook account consistently
Account type stability - Avoid frequent Facebook account type changes
Still having trouble: If the issue persists, please speak with a customer support agent for additional assistance. They can check your specific account situation and provide personalized help.
Pro tip: Write down which login method you used originally (Facebook or Google) to avoid authentication conflicts in the future! Most login issues come from accidentally mixing different authentication methods.
