The OAuth Security Workshop (OSW) is the premier forum for in-depth technical discussions on OAuth, OpenID, and related related technologies.

By fostering a direct and open collaboration between industry professionals, academic researchers, and members of standardization groups, OSW has in a unique way helped to shape and improve internet protocols. It has even played a pivotal role in developing new ones, such as the JWT Access Token Profile, DPoP, and SD-JWT. Leading researchers showcase their cutting-edge results on identity protocol security at OSW.

OSW also serves as an independent venue for the exchange between various working groups (IETF OAuth and GNAP working groups, OpenID Foundation, etc.).

Like the last workshops, OSW 2025 will again consist of a series of pre-submitted and reviewed sessions and an unconference (barcamp-style) part to facilitate less formal exchange regarding ongoing work in the various standardization groups.
