On May 14, 2014, UMA won an award for innovation in information security at the European Identity Conference! We thank the EIC organizers for this honor, and the Kantara Initiative for its support of our efforts – and offer congratulations to all the UMAnitarians. Joni Brennan of Kantara kindly accepted the award on behalf of the UMA WG, and you can see two members of our leadership team, Maciej Machulak (vice-chair) and Domenico Catalano (graphics/UX editor), above.

Don't miss the UMA2 masterclass delivered by two UMAnitarians at the Identiverse conference in Boston in June 2018 (slides and video).

See also the UMA Implementer's Guide, our list of known Implementations, and discussions of Case Studies. Finally, see the detailed UMA Grant sequence diagram and FedAuthz sequence diagram.
