Introduction to Quarkus Security

In this session, Sergey will introduce key Quarkus pillars and explain how Quarkus Security Architecture helps users address real world security requirements.

He will demonstrate how user authentication with multiple OpenId Connect or OAuth social providers can be set up fast, and hope to convince the audience that everyone can do it as fast without being an OpenId Connect or Quarkus Security expert.

He'll finish with a short and fun security quiz.
