XSEDE's Web Single Sign-On (Web SSO) service provides a uniform, consistent, secure way to sign on to web applications using XSEDE user IDs

Dec 11, 2018

XSEDE's Web SSO service is used by applications provided by XSEDE and by XSEDE community members, including the XSEDE User Portal (XUP), the Community Software Repository (CSR), science gateways and other research portals, training websites, and more. Using the XSEDE Web SSO service, any application can use XSEDE user IDs as the basis for its sign-on mechanism.

Applications that offer the "Login to XSEDE" or "Login with XSEDE" buttons (see below) provide a familiar sign-on experience based on XSEDE's user registration and user profiles. XSEDE services use the "Login to XSEDE" button while other services use the "Login with XSEDE" button. Both provide the same experience.

The Web SSO service is based on Globus Auth, an OpenID Connect and OAuth 2.0 service provided by the Globus team at the University of Chicago. XSEDE uses Globus Auth with XSEDE's registry of user IDs and profiles, so applications can count on users being registered with XSEDE and known to other XSEDE services.

For more information about the Web SSO service, see XSEDE's website. Application developers who wish to use the Web SSO service in applications should consult the application developer documentation.
