This WordPress plugin blocks, by default, login attempts for the “admin” user. Because bots and hackers use automated login attempts on WordPress websites, specifically using the “admin” username, it’s a good practice to never use this username. This plugin will block all login attempts that try to use this username.
Features
Block “admin” user only
Block every user, but the usernames in your website.
