I explain the new user attribute functions (UAFs) added in Tableau 2023.1, starting with a refresher on standard user functions like FULLNAME, USERDOMAIN, USERNAME and ISMEMBEROF. I then cover how USERATTRIBUTE and USERATTRIBUTEINCLUDES work for passing dynamic information through connected apps and embedded solutions.

## Key takeaways

- User functions check identity attributes from Tableau Server or Cloud, including full name, user domain, username and group membership via ISMEMBEROF.
- You can impersonate other users by clicking your name in the top-right of a workbook to simulate how a dashboard behaves for different identities.
- User attribute functions let connected apps and embedded solutions pass dynamic attributes (like an application-specific team) that don't need to exist as Tableau groups.
- USERATTRIBUTE checks a single attribute, while USERATTRIBUTEINCLUDES searches an array of attributes for a match.
- You can embed user functions directly into dashboard titles via the Insert tab to personalise text for the logged-in user.
