*  **OkHttp no longer uses the global `java.net.Authenticator` by default.**
    We've changed our `Authenticator` interface to authenticate web and proxy
    authentication failures through a single method. An adapter for the old
    authenticator is available in the `okhttp-urlconnection` module.

 *  Fix: Don't throw `IOException` on `ResponseBody.contentLength()` or `close()`.

* The metrics APIs, `custom-metrics.metrics.k8s.io` and `metrics`, were moved from `v1alpha1` to `v1beta1`, and renamed to `custom.metrics.k8s.io` and `metrics.k8s.io`, respectively. If you have deployed a custom metrics adapter, ensure that it supports the new API version. If you have deployed Heapster in aggregated API server mode, upgrade Heapster to support the latest API version.

* Fix adding disks to more than one scsi adapter. ([#42422](https://github.com/kubernetes/kubernetes/pull/42422), [@kerneltime](https://github.com/kerneltime))

/// tip

If you want to **learn FastAPI** in a structured way (recommended), go and read the [Tutorial - User Guide](../tutorial/index.md) chapter by chapter instead.

As you saw in the previous chapter about [Deployment Concepts](concepts.md), there are multiple strategies you can use.

Here I'll show you how to use **Uvicorn** with **worker processes** using the `fastapi` command or the `uvicorn` command directly.

/// info

If you are using containers, for example with Docker or Kubernetes, I'll tell you more about that in the next chapter: [FastAPI in Containers - Docker](docker.md).

# Simple OAuth2 with Password and Bearer { #simple-oauth2-with-password-and-bearer }

Now let's build from the previous chapter and add the missing parts to have a complete security flow.

## Get the `username` and `password` { #get-the-username-and-password }

We are going to use **FastAPI** security utilities to get the `username` and `password`.
