How do I log out of Facebook on all devices?

[Potato Bin Laden]

My friend was robbed, he didn't log out of Facebook on some of his devices and they were stolen. How can he log out of Facebook on all the devices he's on?

[Catia]

he can log in , in any devices then change his password

I think if you change your password a message will appear and say something like "you will be logged out on all devices when doing this". Not sure if there is an easier way to do it.

Change the password.

Click in the upper-right corner of any Facebook page and select Account Settings; Click Security from the menu. you would see active session option, click edit next to it. there you will see all the devices you have logged in. You will also see the option to end any active session on the right side of each entry. end all the activities, then you are automatically logged out of all the devices.
