 In enterprise settings not only do we want to identify who is using a service but also what they are entitled to use. This is where authentication and authorization comes in. In contrast, API tokens provide full access by virtue of possession as long as they are valid/not expired. With that aside, we first provide the solution on AuthN and AuthZ in OPEA using Istio and JWT tokens. Another option is to leverage the oauth2-proxy with various OIDC providers for authentication and authorization. Using oauth2-proxy with Istio ensures secure, scalable access control, centralizes user management, and provides seamless single sign-on capabilities, improving overall security and user experience in complex microservices environments.

 Currently we provide three kinds of setups for authentication and authorization: via fake JWT token, via JWT token generated by OIDC providers and via oauth2-proxy and OIDC providers. And here we use the chatQnA pipeline as an example.
