## `Security()`

For many scenarios, you can handle security (authorization, authentication, etc.) with dependencies, using `Depends()`.

But when you want to also declare OAuth2 scopes, you can use `Security()` instead of `Depends()`.

You can import `Security()` directly from `fastapi`:

```python
from fastapi import Security
```

import static org.eclipse.aether.impl.scope.BuildScopeQuery.select;
import static org.eclipse.aether.impl.scope.BuildScopeQuery.singleton;
import static org.eclipse.aether.impl.scope.BuildScopeQuery.union;

            OAuth2 scopes required for the *path operation* that uses this Security
            dependency.

            The term "scope" comes from the OAuth2 specification, it seems to be

### <abbr title="Geltungsbereich">`scope`</abbr> { #scope }

Ferner sagt die Spezifikation, dass der Client ein weiteres Formularfeld "`scope`" („Geltungsbereich“) senden kann.

Der Name des Formularfelds lautet `scope` (im Singular), tatsächlich handelt es sich jedoch um einen langen String mit durch Leerzeichen getrennten „Scopes“.

Jeder „Scope“ ist nur ein String (ohne Leerzeichen).

The spec also states that the `username` and `password` must be sent as form data (so, no JSON here).

### `scope` { #scope }

The spec also says that the client can send another form field "`scope`".

The form field name is `scope` (in singular), but it is actually a long string with "scopes" separated by spaces.

Each "scope" is just a string (without spaces).

They are normally used to declare specific security permissions, for example:

### `scope` { #scope }

La especificación también indica que el cliente puede enviar otro campo del formulario llamado "`scope`".

El nombre del campo del formulario es `scope` (en singular), pero en realidad es un string largo con "scopes" separados por espacios.

Cada "scope" es simplemente un string (sin espacios).

### `scope` { #scope }

В спецификации также говорится, что клиент может передать еще одно поле формы — `scope`.

Имя поля формы — `scope` (в единственном числе), но на самом деле это длинная строка, состоящая из отдельных "scopes", разделенных пробелами.

Каждый "scope" — это просто строка (без пробелов).
