I'm getting several login attempts in the admin area of my site. Some robot is trying to figure out the username and password for my admin area. I already set up WP Defender to block the user and the IP number, but this robot changes IP every time I try again.
I can not change the URL because my site has integration with other systems. If I change the URL it will give a problem with the other systems.
I have also added Google Captcha ...
Please, help me
