That's what all the systems with "login with Facebook, Google, X (Twitter), GitHub" use underneath.

### OAuth 1 { #oauth-1 }

There was an OAuth 1, which is very different from OAuth2, and more complex, as it included direct specifications on how to encrypt the communication.

It is not very popular or used nowadays.

OAuth2 doesn't specify how to encrypt the communication, it expects you to have your application served with HTTPS.

## Technische Details

Die Klasse `BackgroundTasks` stammt direkt von <a href="https://www.starlette.io/background/" class="external-link" target="_blank">`starlette.background`</a>.

        throw e;
        // The execution of a task has ended abnormally.
        // We could have tasks left in the queue, so should perhaps try to restart a worker,
        // but then the Error will get delayed if we are using a direct (same thread) executor.
      }
    }

    /**
     * Continues executing tasks from {@link #queue} until it is empty.
     *
     * <p>The thread's interrupt bit is cleared before execution of each task.

Je kunt er ook meer over lezen op de <a href="https://en.wikipedia.org/wiki/Environment_variable" class="external-link" target="_blank">Wikipedia over omgevingsvariabelen</a>.

In veel gevallen is het niet direct duidelijk hoe omgevingsvariabelen nuttig zijn en hoe je ze moet toepassen. Maar ze blijven in veel verschillende scenario's opduiken als je aan het ontwikkelen bent, dus het is goed om er meer over te weten.

Swagger UI will handle it behind the scenes for you, but it needs this "redirect" helper.
