WordPress admin site login url is /wp-login.php by default. It is known by all bots, hackers and other spam software which can take a brute force attacks to your website. If you find there are so many records ( ie : 18.104.22.168 – – [29/Nov/2020:00:20:53 -0700] “POST /wp-login.php HTTP/1.1” 200 ) in your website access log, it means your website is under attack by bots. This can cost a lot of your website bandwidth and slow down your web server.
There are two ways to fix such issue. One is to install a third party plugin ( for example : WPS Hide Login ) to hide the default WordPress admin login page url. But if you use this method, you have to remember another WordPress login page url, and the bots request will arrive your web server to give your web server so much spam requests pressure to slow down it’s performance.
We have another method to avoid such attacks without install plugin. In this method, the bots request will never arrive your web server at all, so it can improve your website speed and performance largely. And the login page url is not need to be changed also, you can remember it easily. Now I will tell you how to do it.
