Token Enrichment Authorization
Token Enrichment Authorization is an approach where authorization logic is used to dynamically add claims to identity or access tokens.
Definition
Token Enrichment Authorization is an architecture in which an identity provider consults an authorization engine during token issuance so that claims inserted into ID tokens or access tokens are generated dynamically from policies and context. This makes token content more adaptive than static claim mapping alone.
Why it matters
Token enrichment enables fine-grained, context-aware authorization decisions without requiring additional runtime authorization calls.
The Ariovis perspective
Tokens are part of an access architecture, not a substitute for identity governance or authorization. Their scope, lifetime, validation and revocation must match the risk of the API and user journey.
