CILogon enables researchers to log on to cyberinfrastructure (CI). CILogon provides an integrated identity and access management platform for research collaborations, combining federated identity management (InCommon/eduGAIN) with collaborative organization management (COmanage). CILogon's federated identity management enables researchers to use their home organization credentials to access research applications, rather than requiring yet another username and password to log on. CILogon's collaborative organization management enables research projects to manage attributes, groups, and roles for authorization to research applications (e.g., Jupyter notebooks).
CILogon provides a broad range of identity and access management services for paid subscribers, as documented on the CILogon subscriptions page. Please contact info@cilogon.org if you're ready to subscribe or if you have any questions about CILogon's subscription services.
CILogon also provides basic authentication services at no cost to academic research projects. CILogon's basic authentication services provide authentication to OpenID Connect applications using GitHub, Google, Microsoft, ORCID, and over 5000 identity providers registered in InCommon and other eduGAIN member federations. See our Add Identity Provider page for details on configuring your identity provider to work with CILogon basic authentication. For additional customization options and other added functionality, please consider a paid CILogon subscription.
Visit https://cilogon.org/ to view CILogon's full list of supported identity providers and to try logging on with your preferred provider. Visit https://demo.cilogon.org/ to see an example of how CILogon can be integrated with a web application.
