If you're seeing a "session expired" message on Facebook, it means your login session has become invalid or timed out. This typically happens when you've been inactive for a while, there are browser issues, or Facebook's security settings have changed.
Facebook uses sessions to keep you logged in while you browse, but these sessions expire automatically as a security measure to protect your account from unauthorized access.
Why Your Facebook Session Keeps Expiring
Sessions expire for several common reasons:
- Inactivity timeout: Facebook automatically expires tokens after about 30 minutes of inactivity
- Browser problems: Cached data, cookies, or extensions can interfere with session management
- Security changes: Updates to Facebook's security settings or your account password
- Device issues: Mobile device settings or app conflicts
- Network problems: Unstable internet connections can disrupt sessions
How to Fix the Facebook Session Expired Error
Method 1: Simple Sign In and Out
The quickest fix is often to sign out of Facebook completely and then sign back in. This refreshes your session token and can resolve temporary glitches.

Method 2: Clear Browser Cache and Cookies
Your browser's cached data can cause session conflicts. Here's how to clear it on different browsers:
Google Chrome:
- Click the three-dot menu in the top right
- Go to More Tools > Clear Browsing Data
- Select "Cookies and other site data" and "Cached images and files"
- Click Clear Data

Safari:
- Open Safari menu > Preferences
- Go to the Privacy tab
- Click "Manage Website Data"
- Select Remove All

Firefox:
- Open Firefox menu > Preferences
- Go to Privacy & Security
- Scroll down to Cookies and Site Data
- Click "Clear Data"

Method 3: Check Mobile App Settings
For mobile devices, clear the Facebook app cache:
Android:
- Go to Settings > Apps > Facebook
- Tap Storage > Clear Cache
iPhone:
- Offload the app or reinstall it to clear cached data
- Go to Settings > General > iPhone Storage > Facebook
- Tap "Offload App" then reinstall
Method 4: Update Your Security Software
Security software and browser extensions can sometimes block Facebook's session management. Make sure your security software is up to date and doesn't block Facebook. Try temporarily disabling it to see if that resolves the issue.
Method 5: Try a Different Browser
If the problem persists in one browser, try accessing Facebook from a different browser like Chrome, Firefox, or Safari. This helps determine if the issue is browser-specific.
Method 6: Check Browser Extensions
Some browser extensions, particularly ad blockers and anti-tracking tools, can interfere with Facebook sessions. Try disabling extensions temporarily:
- Chrome: Three-dot menu > More tools > Extensions
- Safari: Safari menu > Preferences > Extensions
Method 7: Reset Proxy Settings
Proxy settings can sometimes block Facebook access. Here's how to check them:
Mac:
- Apple menu > System Preferences > Network
- Select your network service (Wi-Fi/Ethernet)
- Click Advanced > Proxies

Windows:
- Press Windows key + R
- Type the command to reset proxy settings
Method 8: Restart Your Device
A simple device restart can resolve many session issues by clearing temporary files and refreshing network connections.
Method 9: Update the Facebook App
Make sure you're using the latest version of the Facebook app, as older versions may have compatibility issues with current security protocols.
Preventing Future Session Expiration
To minimize session expiration issues:
- Keep your browser and Facebook app updated
- Clear browser cache regularly
- Avoid using too many browser extensions
- Maintain stable internet connections
- Don't stay inactive on Facebook for extended periods
Remember that session expiration is primarily a security feature designed to protect your account. While it can be inconvenient, these steps should help you regain access quickly and prevent frequent occurrences.
