If you need to make your WordPress site private, this plugin makes it possible for 
your users having to log in before being able to view any content on the website.

WP Require Auth

This plugin makes it mandatory to be logged in before viewing any content.

Limit the number of login attempts possible both through normal login as well as using auth cookies.
By default WordPress allows unlimited login attempts either through the login page or by sending special cookies. This allows passwords (or hashes) to be brute-force cracked with relative ease.
Limit Login Attempts blocks an Internet address from making further attempts after a specified limit on retries is reached, making a brute-force attack difficult or impossible.
Features
<ul>
<li>Limit the number of retry attempts when logging in (for each IP). Fully customizable</li>
<li>Limit the number of attempts to log in using auth cookies in same way</li>
<li>Informs user about remaining retries or lockout time on login page</li>
<li>Optional logging, optional email notification</li>
<li>Handles server behind reverse proxy</li>
<li>It is possible to whitelist IPs using a filter. But you probably shouldn’t. 🙂</li>
</ul>

Limit Login Attempts

bad role

We had initial issues and tried again and it is working better.

Getting a lot better.


I absolutely hate bloated plugins, so I love this one. It's simple and works as expected. Guess it's wise to use a plugin such as this one, against brute force attacks.
