by default the index.php which contains the login page of the dashboard is located in the root installation folder of Piwik as well as the piwik.php (tracker) which is referenced in each Web page that is being tracked.
Therefore it is very easy to find out the location of the login page by simply reviewing the HTML source of a page that is being tracked by Piwik.
In order to increase security, is it possible to rename or relocate that index.php file and/or replace it with e.g. some blank page?
Thanks for your suggestions!
