What element does Trusted Authentication create between Tableau Server and web servers?

Trusted Authentication establishes a trusted relationship between Tableau Server and web servers, allowing seamless and secure access to Tableau content without the need for users to repeatedly log in. This mechanism is significant in environments where a web application needs to directly communicate with Tableau Server while maintaining security and ensuring that users do not experience unnecessary login prompts.

In this context, the trusted relationship allows web servers to authenticate users and automatically grant access to Tableau Server resources, making it easier to integrate Tableau visualizations into custom applications. By enabling single sign-on-like behavior, this setup enhances the user experience by streamlining access to data insights.

Other choices like a data-sharing agreement, a direct connection, or a security protocol do not capture the essence of what Trusted Authentication achieves. While data-sharing agreements focus more on the terms of data usage, a direct connection refers to network-level communications, and security protocols pertain to the standards used to secure data transfer, none of these options appropriately describe the specific trust established in this authentication framework between Tableau and web servers.
