If you have forgotten to sign out of your WordPress site on a public computer or lost your smartphone with logged in WordPress access, you can sign out of WordPress remotely from everywhere, but your current session, in just a single click.
After logging in to the backend, click on Profile in the menu on the left. Scroll to the bottom. Click on the button ‘Log Out of All Other Sessions’. As soon as you click on this button, you will be logged out of all other devices (but not the current browser session.)
