## `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
```

## Dependencies errors and return values

You can use the same dependency *functions* you use normally.

### Dependency requirements

They can declare request requirements (like headers) or other sub-dependencies:
