This is because **OAuth2** uses "form data" for sending the `username` and `password`.

///

Run the example with:

<div class="termy">

```console
$ fastapi dev

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

</div>

## Check it { #check-it }

Go to the interactive docs at: [http://127.0.0.1:8000/docs](http://127.0.0.1:8000/docs).

Cela est dû au fait que **OAuth2** utilise des « form data » pour envoyer le `username` et le `password`.

> Is this change backward compatible? Will it break my setup?

This change is not backward compatible for all setups. In particular, the native
Hashicorp Vault integration - which has been deprecated already - won't be
supported anymore. KES is now mandatory if a third-party KMS should be used.

Further, since the configuration data is encrypted with the KMS, the KMS

Das zweite Argument von [`os.getenv()`](https://docs.python.org/3.8/library/os.html#os.getenv) ist der Defaultwert, der zurückgegeben wird.

Wenn er nicht angegeben wird, ist er standardmäßig `None`. Hier geben wir „World“ als den zu verwendenden Defaultwert an.
