Configuring Keycloak with Node-RED in 2025

Hello everyone!

I'm seeking help for a personal project: I'm trying to create a secured infrastructure, based on using Keycloak, to ease identification. I'm new to this kind of thing, and I would really appreciate some help to learn how it works.
I've seen this previous post Help with adminAuth config for OpenID based authentication but I've figured that the keycloak-passport will be deprecated, and I'm not understanding everything.

I'm browsing the internet to find some help, but I find this topic very undocumented for Node-Red use.

Is somebody ready to share some knowledge about this kind of authentification, how it works and how to set it up?

Thanks!
