What is Brute-force Protection for wp-login.php?

Brute-force protection for wp-login.php is a security measure implemented by some web servers, such as LiteSpeed, to protect WordPress websites from brute-force attacks on the wp-login.php page. Brute-force attacks involve trying various username and password combinations until the attacker finds the correct combination and gains access to the website.

With brute-force protection for wp-login.php, the web server limits the number of login attempts from a single IP address within a certain time frame. If the number of attempts exceeds the limit, the IP address is temporarily blocked from accessing the wp-login.php page for a certain period of time. This helps to prevent automated attacks and protect the website from unauthorized access.
