The following code can be used to disable the WordPress change password notification emails.
To use copy into your theme’s functions.php file, below the opening <? line.
// DISABLE default WordPress change password notifications
if (!function_exists('wp_password_change_notification')) {
function wp_password_change_notification($user) {
return;
}
}
How does it work?
The wp_password_change_notification function is the part of the WordPress core that handles the email notification.
It’s also a pluggable function – meaning we can call it through a theme or a plugin and completely override it.
The code above does this and returns nothing, meaning no email is created or sent when it is triggered by a user changing their password.
