The `OAuth2PasswordRequestForm` is not a special class for **FastAPI** as is `OAuth2PasswordBearer`.

`OAuth2PasswordBearer` makes **FastAPI** know that it is a security scheme. So it is added that way to OpenAPI.

But `OAuth2PasswordRequestForm` is just a class dependency that you could have written yourself, or you could have declared `Form` parameters directly.

        Class<?>[] classes = new Class[l];

        for (int i = 0; i < l; ++i) {
            Object arg = args[i];
            // if we are careful down below, a null argument goes in there
            // so we can know that the null was passed to the method
            classes[i] = arg == null ? null : arg.getClass();
        }

        return getMostSpecific(methodList, classes);
    }

In this case, it is an `async` function.

You could also define it as a normal function instead of `async def`:

/// note

If you don't know the difference, check the [Async: *"In a hurry?"*](../async.md#in-a-hurry){.internal-link target=_blank}.

By returning the result of calling `generate_html_response()`, you are already returning a `Response` that will override the default **FastAPI** behavior.

But as you passed the `HTMLResponse` in the `response_class` too, **FastAPI** will know how to document it in OpenAPI and the interactive docs as HTML with `text/html`:

Here are some of the available responses.

    // that have the same key. Then a second pass will remove all but the first of the slots that
