Keycloak issues access tokens as JSON Web Tokens (JWTs) containing configurable claims like expiry, issuer, email_verified and username and you can map claims to scopes, set defaults or optional, and choose which token types carry each claim. Authentication code flow serves users, client credentials serve services, and token exchange is now standard‑compliant so the token endpoint swaps tokens to the right audience and scopes. Admin UIs and custom mappers exist to build the exact token shape needed.
