You can change the default login page address after installing and activating this plugin. That is the only security this plugin provides other security features will require additional plugins. From the admin console of your website, go to General > Settings and scroll to the bottom of the page. Now change the login page to whatever you want. BUT be sure to document what you change the login page to or you will be unable to log in. If you become locked out due to losing the new login link, you will need to remove this plugin using an FTP client to rename or delete the folder for this plugin.
