InCommon Service

Purdue is a member of the InCommon Federation. The InCommon Federation manages federated authentication services between higher education institutions and their sponsored partners.

As a member, Purdue faculty, staff, and students are able to access resources made available by other participants using their Purdue career account. All participants in the federation, like Purdue, use a common set of policies and practices to exchange information about their users and resources in order to share access to resources and enable collaboration between participants.

The underlying technology used to support federated authentication between participants in the InCommon Federation is the Shibboleth System, with Purdue's Centralized Authentication Service providing the single sign-on protocol for authenticating Purdue faculty, staff, and students using their career account.

IT development staff may visit the Purdue InCommon page for additional information about this service.
