Many people stay logged into Facebook on old phones, shared computers, tablets, or devices they forgot about. Sometimes a lost phone or a suspicious login makes it important to log out everywhere at once. Facebook includes a tool that lets you remove access from all devices quickly. This guide explains how to find that tool and use it safely, in simple steps.
Where to Find Facebook’s Security and Login Settings
Facebook keeps its logout tools inside the Security and Login section. You can reach it from both the app and the website.
In the Facebook app, tap the menu icon, scroll down, and open Settings and Privacy. Then choose Settings, then Security and Login. On the desktop site, the same menu appears under your profile picture in the top bar.
This section shows all the places where your account is currently logged in. It lists phones, browsers, tablets, and any location that has access to your account.
How to Check All Devices You Are Logged In On
Inside the Security and Login page, you will see Where You’re Logged In. This section shows:
- device type
- approximate location
- time of last activity
- browser or app used
Each session helps you confirm if the login is yours. If you see something you don’t recognize, you can log out immediately and secure your account.
Facebook may show older sessions that stayed active for weeks or months, especially on devices you used in the past.
Log Out of Facebook on Every Device at Once
If you want to sign out everywhere with one action, follow these steps:
- Open Facebook Settings.
- Go to Security and Login.
- Find the Where You’re Logged In section.
- Scroll down and tap Log Out of All Sessions.
- Confirm the action when Facebook asks.
This removes your account from every device except the one you are currently using. It helps when you think someone else might still have access.
Log Out of Specific Devices Only
Sometimes you only want to remove a single device instead of logging out everywhere. This is helpful when you spot an old login or a device you no longer use.
To log out of one device:
- Find the device in Where You’re Logged In
- Tap the three dots beside it
- Choose Log Out
This closes that session without affecting your other devices.
What to Do If You See Unknown Devices?
If you notice a device or location that you do not recognize, treat it as a security issue. Log out of that session right away. After that, change your password to prevent someone from logging in again.
It also helps to turn on two-factor authentication. This adds a verification step each time someone tries to sign in. If someone has your password, they still cannot access your account without the second code.
If the unknown login looks serious, check your recent security emails and update all security settings.
Logging Out When You Lose Your Phone
A lost phone is stressful, but Facebook lets you take control from another device. Here’s what to do:
- Log in to Facebook from a computer or another phone
- Go to Security and Login
- Log out of the session that matches your lost phone
- Change your password
- Turn on two factor authentication
Once you log out the lost device, it cannot open your Facebook account anymore.
Extra Security Tools You Should Turn On
Facebook includes useful tools that help protect your account after you log out everywhere.
- Login alerts notify you when a new device signs in.
- Two factor authentication adds a code step for extra security.
- Trusted contacts let friends help if you get locked out.
- Password checks help keep your account strong.
These tools make it harder for anyone else to enter your account without permission.
Common Problems and Simple Fixes
Some users run into small issues while trying to log out on all devices.
- The app does not show the full session list
Try using the desktop site or clear the app cache. - Wrong account logged in
Sign out and switch to the correct Facebook profile. - Locked account
Follow Facebook’s account recovery steps before trying again. - No logout option is showing
Update the Facebook app to the latest version.
These simple fixes solve most access issues.
Final Notes
Logging out of Facebook on every device is easy once you know where the settings are. The Security and Login page gives you full control over your active sessions and helps you protect your account quickly.
