Hi Jeff Maze!
Are you embedding the Tableau views into your own portal or website? If so, you'll want to look at our REST API, specifically this function: https://onlinehelp.tableau.com/current/api/rest_api/en-us/help.htm#REST/rest_api_ref.htm#Sign_Out%3FTocPath%3DAPI%2520Re…
Full documentation of the REST API is here: https://onlinehelp.tableau.com/current/api/rest_api/en-us/help.htm
If you're not embedding the views into your own portal or website, you may want to consider doing so. As an alternative to the REST API, you can also make use of Trusted Authentication, information on which can be found here: Trusted Authentication
Hope this helps!
