How can we make a Tableau Cloud dashboard publicly accessible without requiring users to log in? Is there a supported way to embed a Tableau Cloud dashboard on a public website (e.g. WordPress) while keeping the data hosted in Tableau Cloud?

If you want to embed without authentication and keep data in Tableau Cloud, this site may help you. 

But each viewer needs a Tableau Cloud license. 

If you want truly public access with no license, Tableau Public is better.
