How to Fix Facebook Login Errors on Mobile

Can't log into your Facebook account on your Android or iPhone? Whether it's an "Incorrect Password" error you know is wrong or an unexpected issue, this guide provides the solutions to get you back in.

Why Can't I Log Into Facebook?

Facebook login problems on mobile devices usually boil down to incorrect credentials, network issues, corrupted app data, or a problem with Facebook's servers. It's rarely a permanent issue with your account itself.

Common Causes:

Incorrect Password: The most common reason. It's easy to forget a password or make a typo, especially with caps lock on.
Poor Internet Connection: The app can't communicate with Facebook's servers to verify your login details.
Corrupted App Cache: Temporary files stored by the Facebook app can become corrupted and cause login glitches.
Outdated Facebook App: An old version of the app might have bugs or be incompatible with current security protocols.
Facebook Server Outage: Sometimes, the problem is on Facebook's end.
Incorrect Date & Time: If your phone's clock is wrong, it can cause security certificate errors.

Step-by-Step Fixes for Login Problems

1. Reset Your Password

If you're seeing an "Incorrect Password" error, don't keep trying. Reset it to be sure.

On the Facebook login screen, tap on "Forgotten password?".
Follow the instructions to find your account (using email or phone number) and have a password reset code sent to you.
Create a new, strong password and try logging in with it.

2. Check Your Internet Connection

Ensure your phone has a stable connection to the internet.

Try opening a website in your browser to confirm you are online.
Switch from Wi-Fi to your mobile data (e.g., 4G/5G), or vice-versa. A different network might be more stable.
Restart your router if you're on Wi-Fi.

3. Clear Facebook App Cache

This gets rid of temporary files that could be causing the glitch.

On Android: Go to Settings > Apps > Facebook > Storage & cache, then tap "Clear Cache".
On iPhone: The simplest way is to "offload" the app. Go to Settings > General > iPhone Storage > Facebook, and tap "Offload App". Then, tap "Reinstall App".

4. Restart Your Phone & Update the App

A classic fix that clears up memory and software conflicts.

Turn your phone off completely, wait 30 seconds, and turn it back on.
Go to the App Store or Google Play Store, search for Facebook, and tap "Update" if an update is available.

What NOT To Do

Do not enter your password into third-party websites or apps that claim to fix Facebook issues or offer to get your account back. These are phishing scams designed to steal your credentials. Only ever enter your password on the official Facebook app or website.

Quick FAQs

Why does Facebook say "An unexpected error occurred"?

This is a generic error that often points to a temporary network issue or a problem on Facebook's end. Check your connection and try again in a few minutes. Checking if Facebook is down (see below) is a good idea.

Can I log in if I don't have access to my old email or phone number?

It's very difficult. This is why it's crucial to keep your recovery information up to date. You can try the "Forgotten password?" flow and look for an option that says "No longer have access to these?" to see if you have other recovery methods set up, like Trusted Contacts.

My account is locked or disabled. Is that a login error?

No, that's a different issue. If your account is locked or disabled, Facebook will show you a specific message explaining why and provide steps for you to follow to appeal the decision or verify your identity. This guide is for when the login process itself is failing.
