Knowing how to logout from fb is essential when you share devices, use public computers, or simply want to protect your personal information from unauthorized access. Leaving an active session running on a borrowed phone or a library PC leaves your private messages, photos, and personal data vulnerable to anyone who picks up the device.
This guide walks you through terminating your Facebook sessions across desktop browsers, iPhone, and Android devices. You'll also learn how to remotely log out of all active devices at once and troubleshoot persistent auto-login loops.
How to Log Out of Facebook on Desktop
When you're browsing on a computer using Chrome, Safari, Edge, or Firefox, signing out takes just a few clicks. Facebook keeps the menu hidden behind your profile picture icon in the top right corner.
- Open your web browser and go to Facebook.
- Click your profile picture or the account menu icon in the top-right corner of the screen.
- Select Log Out from the bottom of the dropdown list.
Once you click that button, Facebook terminates your active session token for that browser. If you try to hit the back button, you'll see a login screen instead of your feed.
How to Log Out of Facebook on Mobile Apps
The mobile interface hides the logout option inside the main navigation menu. The steps vary slightly depending on whether you're using an iPhone or an Android device.
On iOS (iPhone and iPad)
- Open the Facebook app and tap the Menu icon (your profile picture with three small lines) in the bottom-right corner.
- Scroll all the way down to the bottom of the menu screen.
- Tap Log Out and confirm your choice when prompted.
On Android Devices
- Open the Facebook app and tap the Menu icon (three horizontal lines) in the top-right corner.
- Scroll to the very bottom of the menu panel.
- Tap Log Out and confirm the prompt to finish signing out.
How to Remotely Log Out of All Devices
If you lost your phone, left your account logged in at a public library, or suspect someone else accessed your profile, you don't need physical access to those devices to secure your account. Facebook lets you terminate sessions remotely from any logged-in device.
- Open Facebook on your computer or phone browser.
- Go to Settings & Privacy and select Settings.
- Open the Accounts Center and click on Password and Security.
- Look for the Where you're logged in section and select your account.
- Review the list of active sessions and devices.
- Click Select devices to log out or choose specific sessions to terminate immediately.
According to guidelines from the Federal Trade Commission, checking your active logins regularly is one of the easiest ways to spot and stop unauthorized account access early.
Troubleshooting Common Logout Problems
Sometimes signing out doesn't work as smoothly as expected. Here is how to fix the most common roadblocks.
Browser Auto-Login Loops
If you click log out, but your browser immediately signs you back in the next time you open Facebook, your browser's password manager or cookie cache is saving your session credentials. To fix this, open your browser settings, navigate to privacy and security, and clear your stored cookies and site data for facebook.com.
The App Keeps Freezing
If the mobile app freezes when you try to tap the logout button, force-close the app entirely through your phone's task manager. Reopen the app, turn off your Wi-Fi or cellular data temporarily so it can't reach the server, tap logout, and then reconnect your internet.
Common Mistakes to Avoid
Many users assume closing a browser tab or locking a phone screen equals logging out of Facebook. It doesn't. Session cookies remain active in the background, allowing anyone who opens the browser or app to bypass the password screen. Always use the explicit logout button when using shared hardware.
Another frequent oversight is ignoring third-party app permissions. If you logged into external games or websites using your Facebook credentials, those apps maintain active tokens even after you sign out of the main site. Review your connected apps under your account settings to revoke access for services you no longer use.
Frequently Asked Questions
Does logging out delete my Facebook posts or photos?
No. Logging out simply ends your active session on that specific device. Your photos, messages, timeline, and account data remain safely stored on Facebook's servers.
Will logging out of Facebook on my phone delete the app?
No. Logging out only signs your user profile out of the application. The app stays installed on your phone home screen, but you'll need to enter your password again to access your account.
Why do I stay logged in even after clicking log out?
This usually happens because your web browser has your username and password saved in its auto-fill storage. Clearing your browser's cookies and saved login credentials will stop it from automatically signing you back in.
How do I know if someone else is logged into my account?
Check the Where you're logged in section inside your Facebook Account Center security settings. It displays a list of every device, city, and login method currently active on your account. If you see an unfamiliar device or location, log it out immediately and change your password.
