Password protect links

Hi there,

I have a client website who needs to list his catalogues (PDF) but the actual files need to be password protected. When a visitor clicks on the hyperlink, they need to be shown a password prompt.

I've tried the Password Protect plugin but that hides the name of the hyperlinks - where I actually need the names to be visible.

I've also tried a plugin called Download Manager but that replaces the download link with a Download image and will be too complicated for my client to manage.

Has anyone had any luck here?
