Web Discovery Project

On this page What-is-the-Web-Discovery-Project- it says …

All URLs sent must be publicly available—that is, they must have the same content regardless of who is contributing them. This can only be true if the pages are not behind a log-in, individual session, or other authentication.

Not quite true. I use several FREE websites related to family history research that have OPTIONAL login pages. If an account is created and login is used; then advanced search options are available. Technically, the webpage changes with login because search form is different; but otherwise page content is the same. When any item in search results is selected; presentation of that item is identical with or without login.

Will “Web-Discovery-Project” ignore these sites because login was used to access them?
