Restricting access to KB Articles
KB Support includes an option for you to restrict access to each KB Article you publish.
If an article is restricted, any user attempting to view the article must be logged in to your website. If they are not, they will only see the article excerpt followed by a notice. The remainder of the content, including comments, will not be visible until the user has successfully logged in.

Depending on your settings, users may also be presented with a login form and/or a registration form.
Restricting Access to a KB Article
To restrict access to a KB Article, edit the article and enable the Restrict Access option within the Restrictions side meta box before publishing or updating your article.

You can have all new articles set as restricted by default by enabling the Restrict KB Articles option within the Global KB Article Settings screen.
