Our single sign-on offerings at the University of Pennsylvania are undergoing a significant transition. Currently, we have two single sign-on offerings: CoSign and Shibboleth (SAML). CoSign is on the path to retirement and will no longer be available as a service in October 2018. Across campus, planning should be currently underway to either retire your CoSign services or to migrate them to our Shibboleth (SAML) offering.
