translations, do not use your own. If an existing translation does not use these terms, update it to use them. In the below list, a term or a translation may be followed by an explanation in brackets, which explains when to translate the term this way. If a translation is preceded by «NOT», then that means: do NOT use this translation for this term. English nouns, starting with the word «the», have the German genus – «der», «die», «das» – prepended to their German translation, to help you to grammatically...

Let's imagine that you have your **backend** API in some domain.

And you have a **frontend** in another domain or in a different path of the same domain (or in a mobile application).

And you want to have a way for the frontend to authenticate with the backend, using a **username** and **password**.

We can use **OAuth2** to build that with **FastAPI**.

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.
