Advanced Authentication patterns at the Edge

This talk focuses on managing authentication in a microservices architecture through the use of an API gateway, rather than implementing it independently for each service. The speaker addresses the challenges that arise from this approach, including identifying users, retrieving user information, imposing logout, and handling authorization. Dennis Jannot explores various authentication mechanisms, such as OAuth and JWT, and offers practical examples and demonstrations on overcoming these challenges, including passing user information using headers generated from claims and performing authorization with OPA.
