The Shibboleth® system provides web authentication services based on industry standards for federated single sign-on between organizations. It is based on the SAML (Security Assertion Markup Language) standard published by OASIS (Organization for the Advancement of Structured Information Standards).
Shibboleth provides the UW community with a standards-based solution for UW users to access internal and external web applications and for external users to access UW web applications. Capabilities include support for authentication, user attribute assertions, authorization, privacy, and federations.
The UW is a member of the InCommon™ Federation, which links US universities and service providers to provide interoperable authentication for a wide variety of web-based applications. As an InCommon participant, the UW publishes a statement about its operational practices related to identity management.
