The MainWP Dashboard Lock Extension allows you to limit access to your Admin area and even redirect Non-WP-Admin pages to a different site making your MainWP Dashboard virtually invisible.
All of these changes can be made without you having to ever edit the .htaccess file yourself.
Frontend Redirect Rules
Make your dashboard front page inaccessible to everyone but you. Easily set a redirect URL, and all hits on Non-WP-Admin pages will be redirected to it. This will make your MainWP Dashboard site virtually invisible.
The Extension allows you to limit access to Admin area pages and to your wp-login.php page to specific IP addresses without having to manually edit your .htaccess file.
Additional IPs can be set up to access your WordPress admin by adding one IP address per line if you access your dashboard from multiple locations.
You can also add a secondary login and password for your Admin area pages and to your wp-login.php page. This is helpful if you have a dynamic IP but still want to add some extra protection to your site.
