How to Sign Out of Facebook on All Devices
To fully log out of Facebook everywhere, start with the device where you are currently signed in. Each platform has a clear path to the logout function.

How to Sign Out of Messenger on All Devices
Messenger maintains separate sessions, so you must sign out explicitly on each platform to ensure no lingering access.
Desktop and Web Versions

Mobile Messenger Apps

Clearing Cached Sessions and Active Logins
After logging out, clearing cached data and reviewing active sessions adds a strong extra layer of protection.
Browser Cache and Cookies
Open your browser settings, go to History and Privacy, and clear cached images, cookies, and site data related to Facebook and Messenger. This removes tokens that could automatically sign you back in.
Reviewing Facebook Login Alerts
Visit Security and Login in Facebook Settings to view where you are logged in. Use Log Out from inactive devices and enable alerts for future logins to spot unauthorized access quickly.
