# Security Tools

When you need to declare dependencies with OAuth2 scopes you use `Security()`.

But you still need to define what is the dependable, the callable that you pass as a parameter to `Depends()` or `Security()`.

There are multiple tools that you can use to create those dependables, and they get integrated into OpenAPI so they are shown in the automatic docs UI, they can be used by automatically generated clients and SDKs, etc.

        }
    }

    @DisplayName("Interface Method Contract Tests")
    class InterfaceMethodContractTests {

        @Test
        @DisplayName("Should define getSID method returning SID")
        void shouldDefineMethods() {
            ACE ace = mock(ACE.class);
            SID mockSid = mock(SID.class);
            when(ace.getSID()).thenReturn(mockSid);

Zum Beispiel stellt eine der Möglichkeiten, die OAuth2 Spezifikation zu verwenden (genannt <abbr title='„Passwort-Fluss“'>„password flow“</abbr>), die Bedingung, einen `username` und ein `password` als Formularfelder zu senden.

```console
$ pip install python-multipart
