## `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

    // List<Authentication> basicAuthList = new ArrayList<Authentication>();
    // basicAuthList.add(new AuthenticationImpl(
    // new AuthScope("www.hoge.com", 80),
    // new UsernamePasswordCredentials("username", "password"),
    // digestScheme));
    // paramMap.put(
    // HcHttpClient.AUTHENTICATIONS_PROPERTY,
    // basicAuthList.toArray(new Authentication[basicAuthList.size()]));
    //
