The purpose of the UMA Work Group (charter) is to develop specs that let an individual control the authorization of data sharing and service access made between online services on the individual's behalf, and to facilitate interoperable implementations of the specs. Read the spec, join the group, get involved!

User-Managed Access (UMA) is an award-winning OAuth-based protocol designed to give an individual a unified control point for authorizing who and what can get access to their digital data, content, and services, no matter where all those things live. Read the specs, join the group, check out the implementations, follow us on Twitter, get involved!

The group is currently working on extensions to UMA V2.0.
