Hi @kaustubhgupta, Based on the provided information, here are the answers to your questions.
1. Do we have a way to add o-auth for DBX-based connections?
- For AWS, Databricks does support OAuth for DBX-based connections. However, it's noted that only users enrolled in Tableau's internal identity provider (IdP) can authenticate using OAuth. For Azure, the Azure Active Directory is used for authentication, but it's not explicitly mentioned if it's OAuth [source](https://docs.databricks.com/partners/bi/tableau.html).
2. If not o-auth, can we somehow store the PA token in the Tableau Server and use that for every new data source added?
- The provided information does not explicitly state that you can store a PA token in Tableau Server for use with every new data source.
However, it does mention that you can use a Databricks personal access token for authentication when connecting to Tableau.
[source](https://docs.databricks.com/partners/bi/tableau.html).
It's recommended to use personal access tokens belonging to service principals instead of workspace users for security purposes.
