Configuring Keycloak Configure and start Keycloak.

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

Keycloak Performance Benchmarks: A Deep Dive into Scaling and Sizing (26.4) Keycloak demonstrates near-linear vertical scaling, performs well in low-latency environments, and effectively offloads database usage with caching.

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 Authenticating users can start simple with a username and a password for each user. But you will also need to handle forgotten passwords ...

#Keycloak at #FrOSCon - we shared how you can run a #sovereign identity management, and listened to the stories of those who are already using it.

Chatham House Rule The Chatham House Rule is used around the world to encourage inclusive and open dialogue in meetings.

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."
