May be you logged into your Facebook account in your friend’s computer and you are not sure if you have logged out. Or you are worried if someone else has your password and access to your account. Thankfully, Fb tracks all your log-in’s, where you are logged in from and when you did. So you can see every device logged into your account, and end any sessions you don’t want active.
Facebook provides data on the location, the device or browser used, and the last accessed date or time for every active login session. If you see any unfamiliar devices or locations, you can end those sessions from your current one.
To find out where your account is currently logged in, open a web browser, log into Facebook, and go to the Facebook account settings page. Then, click “Security” on the left side of the browser window.
On the Security Settings page, click on the “Where You’re Logged In” section. There’s an “Edit” link, but you can click on any part of the section to view and edit it.
The Where You’re Logged In section expands. All your logged in sessions are listed under headings for each platform or device, showing the number of active sessions on that device. Click on a heading that has at least one active session to expand it and see the details of each session.
When you’re finished ending active Facebook sessions, click “Close” at the bottom of the section to close it.
Now that you see how easy it is to check on your active Facebook sessions, you can keep a close eye on your account, making sure you’re not logged in where you don’t want to be.
