### Security and authentication

Security and authentication integrated. Without any compromise with databases or data models.

All the security schemes defined in OpenAPI, including:

* HTTP Basic.
* **OAuth2** (also with **JWT tokens**). Check the tutorial on [OAuth2 with JWT](tutorial/security/oauth2-jwt.md){.internal-link target=_blank}.
* API keys in:
    * Headers.

    OAuth2PasswordRequestForm,
    OAuth2PasswordRequestFormStrict,
    OpenIdConnect,
    SecurityScopes,
)
```

## API Key Security Schemes

::: fastapi.security.APIKeyCookie

::: fastapi.security.APIKeyHeader

::: fastapi.security.APIKeyQuery

## HTTP Authentication Schemes

::: fastapi.security.HTTPBasic

::: fastapi.security.HTTPBearer

::: fastapi.security.HTTPDigest

## HTTP Credentials

OpenAPI has a way to define multiple security "schemes".

By using them, you can take advantage of all these standard-based tools, including these interactive documentation systems.

OpenAPI defines the following security schemes:

* `apiKey`: an application specific key that can come from:
    * A query parameter.
    * A header.
    * A cookie.

## Das Theme ändern

Auf die gleiche Weise könnten Sie das Theme der Syntaxhervorhebung mit dem Schlüssel `syntaxHighlight.theme` festlegen (beachten Sie, dass er einen Punkt in der Mitte hat):

```Python hl_lines="3"
{!../../../docs_src/configure_swagger_ui/tutorial002.py!}
```

Obige Konfiguration würde das Theme für die Farbe der Syntaxhervorhebung ändern:

  @ArgumentsSource(TestDataParamProvider::class)
  @ParameterizedTest
  fun httpUrl(testData: WebPlatformUrlTestData) {
    if (!testData.scheme.isEmpty() && !HTTP_URL_SCHEMES.contains(testData.scheme)) {
      System.err.println("Ignoring unsupported scheme ${testData.scheme}")
      return
    }

    if (!testData.base!!.startsWith("https:") &&
      !testData.base!!.startsWith("http:") &&

 * As policy, implementations of this interface are responsible for selecting which cookies to
 * accept and which to reject. A reasonable policy is to reject all cookies, though that may
 * interfere with session-based authentication schemes that require cookies.
 *
 * As persistence, implementations of this interface must also provide storage of cookies. Simple
 * implementations may store cookies in memory; sophisticated ones may use the file system or
