@r-wheeler But here you are passing in the tableau username, ideally in a web app how would you pass in the tableau username dynamically?

In my web app, I have auth0 authentication implemented - so the auth0 login page shows up and the user logs in using their auth0 credentials. Now would the users have to enter the tableau username as well before I can do the Trusted Authentication - or is there another way to get the tableau usernames
