By default, a WordPress user can have an unlimited number of attempts to log-in to a WordPress site. This facilitates hackers to try guessing your password until they get it right. It can cost your important documents at any time and that will hamper your functional stability.
To resolve this problem a super WordPress plugin has introduced named Login LockDown. You just need to install and activate the plugin on your site.
It allows you to set a limit on the number of unsuccessful attempts a user can make to login. It’s simply a cool plugin to handle such kind of situation.
