### 󠀁[2 Step log in work fine! and anti brute force login work good as well.](https://wordpress.org/support/topic/2-step-log-in-work-fine-and-anti-brute-force-login-work-good-as-well/)󠁿

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.
