/// tip

Integrating other authentication/authorization providers like Google, Facebook, Twitter, GitHub, etc. is also possible and relatively easy.

The most complex problem is building an authentication/authorization provider like those, but **FastAPI** gives you the tools to do it easily, while doing the heavy lifting for you.

of ztunnel is to be a minimal L4 proxy, and as such, its xDS configuration is purposefully limited. In particular, ztunnel only supports 2 (custom) xDS resources: [`Workload`](../../pkg/workloadapi/workload.proto) and [`Authorization`](../../pkg/workloadapi/security/authorization.proto). As such, ztunnel does not receive `PeerAuthentication`s directly; when istiod detects a `PeerAuthentication` resource that targets an Ambient captured workload, it computes the effective policy for that workload...
