I have install my plugin to my client websites. Uninstall other security plugins. Active 2 functions of this plugin (2-step verification, Anti brute force). The results look good.
– Website speed improve at wp-admin page.
– Hacker try to hack with xmlrpc.php has been blocked at recapcha page.
– Hacker can not pass 2-step login page.
I wish website that use this plugin will have same experience as well.
