Rename wp-login.php is a plugin that helps prevent brute force attacks targeted specifically to wp-login.php. The module works by changing the login URL.
The wp-admin directory and wp-login.php page become inaccessible, so you
should bookmark or remember the url. Deactivating this plugin brings
your site back exactly to the state it was before.
1. From the WordPress dashboard, navigate to Plugins > Installed Plugins.
2. Find “Rename wp-login.php” and click Activate.
If you’re using a page caching plugin you should add the slug of the new login url to the list of pages not to cache. For W3 Total Cache and WP Super Cache this plugin will give you a message with a link to the field you should update.
I forgot my login url!
First try ‘/login’, as this is the default setting.
Next, go to your MySQL database and look for the value of rwl_page in the options table,
If still not found, remove the folder rename-wp-login from your plugins folder (using FTP or SSH), then log in through wp-login.php and reinstall the plugin.
When using a cache plugin, be sure to exclude to your new login URL!
