CILogon enables researchers to log on to cyberinfrastructure (CI). 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). 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 https://cilogon.org/ 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 https://demo.cilogon.org/ 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.
