Why does Facebook app say login error?

If you are seeing a login error when trying to access Facebook through the mobile app, there are a few potential causes and solutions to try. The Facebook login error is a common problem that many users encounter.

Potential Causes of Facebook Login Errors

Here are some of the most common reasons why the Facebook app may show a login error:

Outdated app version – If you haven’t updated the Facebook app recently, an outdated version could cause login issues. Make sure you have the latest version installed.

Incorrect password – Double check that you are entering your password correctly. If you have changed your Facebook password recently, you will need to update it in the app.
Two-factor authentication enabled – If you have two-factor authentication set up for your Facebook account, you may need to enter a code from your mobile device to log in successfully.
Browser cookies cleared – The Facebook app uses browser cookies to remember your login. If your cookies were recently cleared, the app may not recognize you.

Account security changed – Sometimes Facebook will require additional verification if your account security settings have changed.
Connection issues – Poor internet connection, using mobile data instead of WiFi, or VPN/firewall conflicts can prevent successful login.
Server problems – Login errors can point to temporary technical problems or outages on Facebook’s servers.

Banned or disabled account – If your account was disabled for a violation of Facebook’s policies, you will be unable to log in until it is reactivated.

6 Ways to Fix Facebook App Login Error

If you are seeing the login error message in the Facebook app, try these troubleshooting steps:

1. Update to the Latest Facebook App Version

Outdated app versions commonly cause problems with login functionality. The easiest fix is to update to the latest Facebook app from your device’s app store. The most current iOS version is 317.0 and the most current Android version is 358.0.1. Updating gives you the latest features and security fixes.

2. Check Your Password and Reset If Needed

One of the simplest explanations for a login error is that you’ve forgotten your password or have recently changed it and not updated it in the app. Go to the Facebook website and try logging in with your email and password. If your password is incorrect, use the Forgot Password link to reset it.

3. Disable Two-Factor Authentication Temporarily

If you have two-factor authentication enabled for enhanced account security, you may need to enter a code from your mobile device before you can login. If you cannot access the code, you can temporarily disable two-factor authentication on the Facebook website to access your account.

4. Clear Browser Cookies and Cache

The Facebook app uses browser cookies stored on your device to remember you between logins. Clearing your cookies and cache can sometimes resolve login issues. On iOS, go to Settings > Safari > Clear History and Website Data. On Android, go to Chrome app > Settings > Privacy > Clear Browsing Data.

5. Check Account Security Settings

If your Facebook account security settings were recently changed, you may encounter extra login steps like code verification. Check your account security settings on the Facebook website to see if any changes need to be made to access the app again.

6. Troubleshoot Internet Connectivity

Problems with your internet connection can prevent successful login. Switch from mobile data to a WiFi connection and try again. If you are on public WiFi, there could be firewall or VPN conflicts blocking access, so try a private WiFi network.
