In addition, as the resource servers are now able to directly read the value of the access token, they do not always have to make a request to the OAuth 2.0 token introspection endpoint, or the OpenID Connect UserInfo endpoint. This potentially eliminates two additional requests to Keycloak for a request to the resource server, reducing latency as well as significantly reducing the number of requests to Keycloak.

Stian Thorgersen

Stian Thorgersen started his career at Arjuna Technologies building a cloud federation platform, years before most companies were even ready for a single-vendor public cloud. He later joined Red Hat, looking for ways to make developers' lives easier, which is where the idea of Keycloak started. In 2013, Stian co-founded the Keycloak project with another developer at Red Hat. Today, Stian is the Keycloak project lead and is also the top contributor to the project. He is still employed by Red Hat as a senior principal software engineer focusing on identity and access management, both for Red Hat and for Red Hat's customers. In his spare time, there is nothing Stian likes more than throwing his bike down the mountains of Norway.
