How to log out of your Facebook account on every device, or on all devices at once from your account settings

• You can sign out of Facebook on each device one by one, or on all devices at once through your account's settings.
• It's a good habit to sign out of active sessions on all social media platforms to keep your account safe. 
• Logging out of Facebook on your desktop or mobile device is simple once you know where to look.

With so many devices and so many social media accounts, it can be hard to remember where you're logged in to which accounts. To protect yourself from potential hacks, it's a good idea to log out of social media sites like Facebook once you're done with your session, especially if you're using someone else's device.

But, if you forgot to log out and no longer have access to the device, you can still log out of all devices at once from your Facebook's account settings.

Here's how to log out of Facebook on any device — computer desktop or mobile — one by one, or on all devices at once.
