I found Nate Barbettini's video on OAuth and OpenID Connect incredibly insightful for understanding these topics. He explains everything so well- https://youtu.be/996OiexHze0.

Additionally, I'm part of the ZITADEL team, an open-source project that's free to download or use in our cloud offering. So, you can always tinker around with it as some others have already suggested. Our blog dives into various security topics, ranging from OAuth, OpenID Connect, and Single Sign-On, Authentication, Federation to emerging issues like Passkeys. We also discuss real-world Identity Management problems and solutions seen by ZITADEL users— https://zitadel.com/blog.

For any specific security-related queries, feel free to join the conversation on our Discord chat: https://zitadel.com/chat. We're always discussing and sharing insights on these topics.
