CILogon provides an integrated open source identity and access management platform for research collaborations, combining federated identity management (Shibboleth, InCommon) with collaborative organization management (COmanage). Federated identity management enables researchers to use their home organization identities to access research applications, rather than requiring yet another username and password to log on. Collaborative organization management enables research projects to define user groups for authorization to collaboration platforms (e.g., wikis, mailing lists, and domain applications).

Interested in using CILogon? Please contact for assistance. We'll help you connect your application(s) using OpenID Connect, SAML, X.509, and/or LDAP, and we'll help you manage attributes, groups, policies, and workflows for your collaboration using the CILogon platform. Our subscription model supports multiple service tiers to meet a variety of research collaboration needs. The CILogon platform has been supporting production research applications since 2010.
