# Sicherheit – Erste Schritte

Stellen wir uns vor, dass Sie Ihre **Backend**-API auf einer Domain haben.

Und Sie haben ein **Frontend** auf einer anderen Domain oder in einem anderen Pfad derselben Domain (oder in einer mobilen Anwendung).

Und Sie möchten eine Möglichkeit haben, dass sich das Frontend mithilfe eines **Benutzernamens** und eines **Passworts** beim Backend authentisieren kann.

Wir können **OAuth2** verwenden, um das mit **FastAPI** zu erstellen.
