Trusted authentication lets you set up a trusted relationship between your Tableau Server and the PushMetrics servers. This allows users to open live views without additional authentication to Tableau.
When Tableau Servers receive requests from a trusted web server, it assumes that the web server has already handled whatever authentication is necessary. Tableau Servers receive the request with a redeemable token or ticket and presents the user with a personalized view which takes into consideration the user’s role and permissions.
