Shibboleth is an open-source identity management software that simplifies sharing of online resources between affiliated institutions, while ensuring security and privacy of account information. It is the software platform most identity federations utilize to support federated authentication and user attribute exchange and is used by all the identity federations Texas A&M participates in. Shibboleth is of interest to applications desiring to support access by users both within and across organizational boundaries.
Shibboleth began as an Internet2 project in 2000. In 2013, the Shibboleth Consortium was chartered to support continued development of the software, with Internet2 participating in the Consortium as a principal member.
