Why force all users to log out?

If you’ve logged in to your WordPress admin account on a computer that is not yours, and you’re not sure whether you’ve logged out, this method will make sure that you’re logged out on all devices.

Let’s have a look at the different methods to force all users to log out.

Forcing all users to log out of WordPress

To force your users to log out, you’re going to edit the wp-config.php file. This file can be considered the “heart” of your WordPress install. If you make mistakes here, your website may become unaccessible or stop working. Therefore, I highly recommend to create a proper backup of your wp-config.php file. If you make a mistake, you’ll be able to easily revert to the previous version.

To edit the wp-config file, connect to your server using FTP (or use the File Manager in your hosting company’s control panel). Go to the root folder of your WordPress install and look for the file called wp-config.php.

To force all users to log out, you’ll need to replace these “keys” with a fresh set of random strings. You can enter your own unique phrases, but it’s probably easier to visit this page that will automatically generate a random set of keys for you.
