WG - User Managed Access


What is it?

UMA is an award-winning OAuth-based protocol set that helps individuals manage third-party access to their data, content, and service resources across different identity and resource ecosystems.

Value Proposition

Customers, citizens, employees, and partners all demand dynamic access controls in their online experiences.  Developed via an open and transparent standards-based approach, UMA’s flexibility toward users and enterprise authorization makes it a key business innovation enabler for user-managed, fine-grained data sharing and privacy use cases.
