We have two kinds of docs. In the new guides, look for "Edit this guide" on the right. See www.keycloak.org/server/confi...

In the old guides, some have an "Edit this section", see www.keycloak.org/docs/latest/...

Or create a bug or DM me with the page in question as a fallback :D

We scaled #Keycloak to 2_000 logins per second and 10_000 token refreshes per seconds on #AWS and it scaled linearly in our #loadtest! It performed just fine with the latest optimizations in v26.4.

What load do you run on Keycloak? Do you host your own #IAM?

Delegate authentication and a lot more to Keycloak with OpenID Connect

Today I heard about the "Chatham House Rule" which is very different from the "Vegas Rule":

"[...] participants are free to use the information received, but neither the identity nor the affiliation of the speaker(s), nor that of any other participant, may be revealed."
Chatham House Rule
The Chatham House Rule is used around the world to encourage inclusive and open dialogue in meetings.

The event in Japan went well. It was later renamed as KeycloakCon to fit the naming of other co-located events around KubeCon Japan. The playlist of Japan is now available online: youtube.com/playlist?lis...

In Amsterdam, you will see a different set of speakers, and it might be closer to your home
