    In today’s enterprise world, authentication is almost always delegated to a central, external server: an SSO provider like Keycloak. The obvious answer, token introspection, is a performance-bottleneck nightmare. We will not be making any blocking API calls. Instead, we will perform local, cryptographic validation of KeyCloak’S JWTs using their public JSON Web Key Set.
