### Create the **FastAPI** Code { #create-the-fastapi-code }

* Create an `app` directory and enter it.
* Create an empty file `__init__.py`.
* Create a `main.py` file with:

```Python
from fastapi import FastAPI

app = FastAPI()


@app.get("/")
def read_root():

But if for some reason your clients depend on the old behavior, you can revert to it by overriding the method `make_not_authenticated_error` in your security classes.

For example, you can create a subclass of `HTTPBearer` that returns a `403 Forbidden` error instead of the default `401 Unauthorized` error:

{* ../../docs_src/authentication_error_status_code/tutorial001_an_py310.py hl[9:13] *}

/// tip

   * necessary to support classes defined without generics.
