I want to hide my WordPress site (or any website) from the world and only allow certain users to enter. What's the best way of doing this without setting up user accounts and passwords? Or perhaps more precise, what's the maximum protection I can get without using accounts?
Of course, I've chosen to block search engines under settings->privacy already. But I've thought about blocking people from linking directly to images and files, how can that be done? Is it by putting all the uploads (files/images) in a hidden folder somewhere outside of the WP structure? How do I do that?
