Wordpress - Custom Admin URL
Step 1 - Login to your Wordpress and install the plugin WPS Hide Login.
Step 2 - On the left hand side, click on Settings > General, then scroll to the bottom to input the Login url (in this example, we will be using secretlogin), afterwards, click Save Changes.
NOTE: We recommend taking note of the new admin login page for your site as we cannot assist with recovering the custom login url once changed.
Now you can access your Wordpress admin area through the new admin url.
