Rockstar Games Sign-In (OpenID Connect)
Public OpenID Connect / OAuth 2.0 identity provider operated by Rockstar Games at signin.rockstargames.com. Backs authentication for the Rockstar Games website, Rockstar Games Launcher, Social Club, Rockstar Newswire, and first-party mobile apps. Supports the authorization_code, client_credentials, and refresh_token grant types and exposes /connect/authorize, /connect/Token, /connect/introspect, and a JSON Web Key Set at /.well-known/jwks. Appears to be implemented on an IdentityServer-style stack. Client registration is not open to third parties; only Rockstar-issued client IDs (e.g. the Launcher, Social Club, Newswire) are accepted.
