# HTTP Basic Auth

Für die einfachsten Fälle können Sie <abbr title="HTTP-Basisauthentifizierung">HTTP Basic Auth</abbr> verwenden.

Bei HTTP Basic Auth erwartet die Anwendung einen Header, der einen Benutzernamen und ein Passwort enthält.

Wenn sie diesen nicht empfängt, gibt sie den HTTP-Error 401 „Unauthorized“ zurück.

Und gibt einen Header `WWW-Authenticate` mit dem Wert `Basic` und einem optionalen `realm`-Parameter („Bereich“) zurück.

# HTTP Basic Auth

For the simplest cases, you can use HTTP Basic Auth.

In HTTP Basic Auth, the application expects a header that contains a username and a password.

If it doesn't receive it, it returns an HTTP 401 "Unauthorized" error.

And returns a header `WWW-Authenticate` with a value of `Basic`, and an optional `realm` parameter.

That tells the browser to show the integrated prompt for a username and password.
