Secure Downloads is an add-on which generates encrypted temporary links and send them to users submitted the popup. The workflow is really simple. If visitors want to download certain file, they must submit popup’s form. After submission they receive temporary encrypted URL by e-mail or redirected to encrypted URL. This URL is valid several hours only. As an administrator you can decide where to host files: Media Library, Amazon S3 servers or any 3rd party servers. This add-on works with WordPress version of Green Popups only and requires Green Popups version 7.0 or higher to be installed.
Below are some demos. You can submit the form and receive download link by email. The functionality works with both modes: regular popups and inline popups.
