IITB Central SSO — OpenID Connect
The IIT Bombay Computer Centre's central identity provider, and the credential every institutional service sits behind. It publishes a live OpenID Connect Discovery 1.0 document and a JWKS: issuer https://sso.iitb.ac.in, authorization, token and userinfo endpoints, response_types_supported ["code"], token_endpoint_auth_methods_supported ["client_secret_basic"], and a deliberately minimal scopes_supported of ["openid"]. Interactive sign-in is LDAP plus a second factor — TOTP, a hardware credential, or SMS OTP. Client registration is not self-service; the Gymkhana developer documentation directs external developers to the Computer Centre for IITB SSO integration.
