EVE Single Sign-On (SSO) is one of 50 APIs that [EVE Online](https://apis.io/providers/eve-online/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include Authentication, Authorization, JWT, OpenID, and PKCE. The published artifact set on APIs.io includes API documentation.

EVE Single Sign-On (SSO) is the OAuth 2.0 authorization service for EVE Online third-party applications, hosted at login.eveonline.com. It supports the Authorization Code flow for confidential (server-side) applications and Authorization Code with PKCE for native and single-page apps that cannot keep a client secret. Access tokens are issued as RS256-signed JWTs whose sub claim is CHARACTER:EVE:<character-id>, whose aud must contain both the application client_id and the literal "EVE Online", and whose scp claim lists the granted ESI scopes. The service publishes RFC 8414 metadata at /.well-known/oauth-authorization-server, including authorization, token, revocation, and JWKS endpoints.
