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**.

## Origin { #origin }

Origin; protocol (`http`, `https`), domain (`myapp.com`, `localhost`, `localhost.tiangolo.com`) ve port’un (`80`, `443`, `8080`) birleşimidir.

Dolayısıyla şunların hepsi farklı origin’lerdir:

* `http://localhost`
* `https://localhost`
* `http://localhost:8080`
