VIA's OpenID Connect / OAuth 2.0 identity layer, operated on a VIA-run Keycloak server. It is the only machine-readable contract VIA publishes: each product realm serves an anonymous OIDC discovery document, and the `ztf_demo` realm additionally serves RFC 8414 authorization-server metadata and a UMA 2.0 configuration. Applications integrate with Authorization Code + PKCE (S256) and receive a bearer JWT; Zero Trust Fabric layers passwordless login backed by W3C-style verifiable credentials held in the VIA Wallet, with a wallet signature required to step up for sensitive operations. The realms also advertise DPoP, Pushed Authorization Requests, mTLS-bound access tokens, token exchange, CIBA, the device authorization grant and dynamic client registration.
