# Alte 403-Authentifizierungsfehler-Statuscodes verwenden { #use-old-403-authentication-error-status-codes }

Vor FastAPI-Version `0.122.0` verwendeten die integrierten Sicherheits-Utilities den HTTP-Statuscode `403 Forbidden`, wenn sie dem Client nach einer fehlgeschlagenen Authentifizierung einen Fehler zurückgaben.

## Utilidades de **FastAPI** { #fastapi-utilities }

FastAPI proporciona varias herramientas para cada uno de estos esquemas de seguridad en el módulo `fastapi.security` que simplifican el uso de estos mecanismos de seguridad.

 *       add overloads that accept start and end indexes.
 *   <li>Can be streamed without "breaking the chain": {@code foo.getBarLongs().stream()...}.
 *   <li>Access to all collection-based utilities via {@link #asList} (though at the cost of
 *       allocating garbage).
 * </ul>
 *
 * <p>Disadvantages compared to {@code long[]}:

# Templates { #templates }

You can use any template engine you want with **FastAPI**.

A common choice is Jinja2, the same one used by Flask and other tools.

There are utilities to configure it easily that you can use directly in your **FastAPI** application (provided by Starlette).

## Install dependencies { #install-dependencies }

## **FastAPI** utilitários { #fastapi-utilities }

**FastAPI** fornece várias ferramentas para cada um desses esquemas de segurança no módulo `fastapi.security` que simplesmente usa esses mecanismos de segurança.

In your production system, you probably have a frontend created with a modern framework like React, Vue.js or Angular.

And to communicate using WebSockets with your backend you would probably use your frontend's utilities.

Or you might have a native mobile application that communicates with your WebSocket backend directly, in native code.

Or you might have any other way to communicate with the WebSocket endpoint.
