E você quer uma maneira de o frontend autenticar o backend, usando um **username** e **senha**.

Nós podemos usar o **OAuth2** junto com o **FastAPI**.

Mas, vamos poupar-lhe o tempo de ler toda a especificação apenas para achar as pequenas informações que você precisa.

Vamos usar as ferramentas fornecidas pela **FastAPI** para lidar com segurança.

1) `base` chart creates cluster-wide CRDs, cluster bindings and cluster resources. It is possible to change the namespace from `istio-system` but it is not recommended.

```console
helm install istio-base -n istio-system manifests/charts/base --set profile=openshift
