I am trying to integrate prefect in our pipelines, Is there any we can add password or some kind of user authentication to secure prefect server

Great questions! I’d suggest we move them to #prefect-community to increase the visibility. However, for Prefect server RBAC is not supported. I'll post a Discourse link soon (I think I saw it on there)

This mentions Prefect 2.0, but is also generally valid for Prefect 1.0 (Prefect Server) https://discourse.prefect.io/t/why-does-prefect-2-0-doesnt-include-auth-and-rbac-features-as-part-of-the-open-source-package/741
