# Segurança - Primeiros Passos

Vamos imaginar que você tem a sua API **backend** em algum domínio.

E você tem um **frontend** em outro domínio ou em um path diferente no mesmo domínio (ou em uma aplicação mobile).

E você quer uma maneira de o frontend autenticar o backend, usando um **username** e **senha**.

Nós podemos usar o **OAuth2** junto com o **FastAPI**.

    browser = playwright.chromium.launch(headless=False)
    context = browser.new_context()
    page = context.new_page()
    page.goto("http://localhost:8000/docs")
    page.get_by_role("link", name="/items/").click()
    # Manually add the screenshot
    page.screenshot(path="docs/en/docs/img/tutorial/cookie-param-models/image01.png")

#### Ścieżka

"Ścieżka" tutaj odnosi się do ostatniej części adresu URL, zaczynając od pierwszego `/`.

Więc, w adresie URL takim jak:

```
https://example.com/items/foo
```

...ścieżką będzie:

```
/items/foo
```

/// info

"Ścieżka" jest zazwyczaj nazywana "path", "endpoint" lub "route'.
