Якщо Ви оголосите його як є, то, оскільки це одиничне значення,  **FastAPI**  припускатиме, що це параметр запиту (query parameter).

Але Ви можете вказати **FastAPI** обробляти його як інший ключ тіла (body key), використовуючи `Body`:

In diesem Fall können Sie diese Funktion in **FastAPI** mit dem Parameter `separate_input_output_schemas=False` deaktivieren.

`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.

But as it's a common use case, it is provided by **FastAPI** directly, just to make it easier.
