Disable the ‘Password Changed’ Email notification in WordPress with a filter

Since I didn’t find a solution for this within a second after performing a web search and was recommend other ‘solutions’, here’s the solution to actually fix this; fast.

add_filter( 'send_password_change_email', '__return_false' );

You can add this line to your functions.php or in a separate plugin, whatever works best for you 🙂
