Guidance for Responding to the Question


U-M’s Identity and Access Management modernization efforts call for discontinuing use of outdated protocols, such as Cosign, used to provide access to protected web resources at U-M.

Cosign has been the university’s secure single sign-on web authentication system for more than 20 years. Originally designed at U-M, the open source software was once widely used across higher education. Now, however, only a handful of universities still use Cosign, and the open source community that once maintained and developed it has dwindled.

How to Migrate from Cosign

Unit IT staff responsible for services currently using Cosign should:

  1. Review the information on the Shibboleth at U-M website.
  2. Use the Shibboleth Configuration Request Form to submit a request for each system that needs to be migrated from Cosign to one of the now preferred protocol options - SAML or OIDC.

If you need help with your transition efforts, please contact the ITS Identity & Access Management team (IAM) team at
