## **FastAPI**'s `OAuth2PasswordBearer` { #fastapis-oauth2passwordbearer }

**FastAPI** provides several tools, at different levels of abstraction, to implement these security features.

In this example we are going to use **OAuth2**, with the **Password** flow, using a **Bearer** token. We do that using the `OAuth2PasswordBearer` class.

## Run Distributed MinIO on Containers

We recommend kubernetes based deployment for production level deployment <https://github.com/minio/operator>.

See the [Kubernetes documentation](https://docs.min.io/community/minio-object-store/operations/deployments/kubernetes.html) for more information.

This *path operation*-specific OpenAPI schema is normally generated automatically by **FastAPI**, but you can also extend it.

/// tip

This is a low level extension point.

If you only need to declare additional responses, a more convenient way to do it is with [Additional Responses in OpenAPI](additional-responses.md){.internal-link target=_blank}.
