TL;DR

AI summary of the plugin's readme

This plugin is for WordPress site administrators who want to strengthen login and site security without editing server configuration files. It reduces the risk of unauthorized access and abuse by limiting login attempts, adding captcha and two-factor authentication, hiding version and author information, and disabling vulnerable features like XML-RPC and REST API.
