External Identities Working Group

The mission of the External Identities Working Group is was to move the community of knowledge towards the goal of making external identities useful and sufficiently trusted in a variety of campus-based use cases. This group is Chaired by Eric Goodman of the University of California, Office of the President, this group was focused on the use of external identities by individuals, rather than an enterprise using an external identity provider as their enterprise IdP.

Specific goals for the External Identities Working Group includeincluded:

• Exploring/developing deployment models for using external identities in a variety of risk profiles
• Identifying and examining the technical components that are needed to make external identities useful across a broad array of services
• Exploring the notion of account linking between a campus-issued account and an external account
• Understanding the differences between external identities and local identities

Membership in the Working Group is open to all interested parties. Members join the Working Group by subscribing to the mailing list, participating in the phone calls, and otherwise actively engaging in the work of the group.  The Working Group is expected to complete its work by December 31, 2014.
