CILogon – A Federated Identity and Access Management Service Supporting NSF Research Infrastructure

The CILogon ( identity and access management service at the University of Illinois has been serving the NSF community since 2010. CILogon clients include CloudBank, CyVerse, FABRIC, Globus, LIGO, LSST, NEON, OOI, OSG, and PRP. CILogon combines 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). CILogon implements the AARC Blueprint Architecture and the REFEDS Assurance Framework. CILogon supports over 4000 identity providers, including campus identity providers, GitHub, Google, and ORCID. Visit to view the full list of identity providers and to try logging on with your preferred provider. See our Add Identity Provider page for details on configuring your identity provider to work with CILogon. Visit to see an example of how CILogon can be integrated with a web application. CILogon is a research and scholarship service provider in the InCommon federation, and CILogon is an InCommon Catalyst. CILogon is an open source project, with source code in GitHub.
