So, let's review it from that simplified point of view:

* The user types the `username` and `password` in the frontend, and hits `Enter`.
* The frontend (running in the user's browser) sends that `username` and `password` to a specific URL in our API (declared with `tokenUrl="token"`).
* The API checks that `username` and `password`, and responds with a "token" (we haven't implemented any of this yet).

  skipApprovalScreen: false
  # If only one authentication method is enabled, the default behavior is to
  # go directly to it. For connected IdPs, this redirects the browser away
  # from application to upstream provider such as the Google login page
  alwaysShowLoginScreen: false
  # Uncommend the passwordConnector to use a specific connector for password grants
  passwordConnector: local

Wenn Sie versuchen, mit einer der beiden Benutzeroberflächen zu interagieren, funktionieren diese ordnungsgemäß, da der Browser mit jeder spezifischen Anwendung oder Unteranwendung kommunizieren kann.

### Technische Details: `root_path`

# Cookie-Parameter

So wie `Query`- und `Path`-Parameter können Sie auch <abbr title='Cookie – „Keks“: Mechanismus, der kurze Daten in Textform im Browser des Benutzers speichert und abfragt'>Cookie</abbr>-Parameter definieren.

## `Cookie` importieren

Importieren Sie zuerst `Cookie`:

If you try interacting with any of the two user interfaces, they will work correctly, because the browser will be able to talk to each specific app or sub-app.
