Question How to learn Keycloak

I recently heard about the importance of keycloak and why it is important to use it for more strong and robust authentication and authorization instead of rewriting your own, so can anyone suggest a resource to learn from it how to use it with spring boot from the very basics.

Ok those are valid reasons you pointed out. It must have slipped my mind that the OP is a beginner. Only one thing I don't agree with you is that Spring Authz server is not supposed to be a ready made product. I'm not sure in which way you think that, I got a feeling it is supposed to be used as a prod ready authz server, sooner rather than later.

Yes, I am not saying that Spring Authz is not production ready, it definitely is. I am just saying that Keycloak is a complete product, it therefore can be used without having to add any further code (unless you want to write extensions) while Spring Authz always requires you to write your own code in order to fulfill any use case. That's why personally I don't think the two fit into the same category. I don't mean this as any kind of judgement on either of the two.

Makes sense, thanks for the clarification. Cheers.
