Plugins are not all created equally, especially when they require an API key, which BruteForce does. However, the BruteForce team has made the installation of this PlugIn amazingly easy. The plugin finds your WordPress setup email address and quickly emails you the API key with the press of a button, which you then input on the same page with no reloading.
Since we have just installed it on our SEO and social media software blog at http://theseosystem, we have not yet seen the results, but we can assume that they are good based on other's feedback.
If the simplicity and design of the installation is any indication, this plugin is perfect for protecting your wp-login.php file.
