Log Out on All Devices from the Facebook Mobile App

If you use an iPhone, iPad, or Android phone, you can use the official Facebook app to sign out from Facebook on all your devices at once.

To use this method, launch the Facebook app on your phone.

In the Facebook app, tap the three horizontal lines menu. On an iPhone or iPad, this menu is at the bottom of the app. On an Android phone, you’ll find this menu at the top-right corner of the app.

Scroll down the “Menu” screen that opens, and tap “Settings & Privacy.”

From the “Settings & Privacy” menu options, select “Settings.”

Scroll down the “Settings” screen to the “Security” section. Here, tap “Security and Login.”

On the “Security and Login” page, next to the “Where You’re Logged In” header, tap “See All.”

Facebook will display the list of devices where you use your account. At the bottom of this screen, tap “Log Out of All Sessions.”

On the “Log Out of All Sessions” page that opens, select “Log Out.”

And you’re all set. You’re signed out from whatever device you use your Facebook account on.
