WPS Hide Login Lite
Based on the WPS Hide Login plugin for WordPress, but with all bullshit removed.
This plugin lets you easily and safely change the url of the login form page to anything you want. It doesn’t literally rename or change files in core, nor does it add rewrite rules. It simply intercepts page requests and works on any WordPress website. 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.
