Electronic ID card

If authentication is to be performed via the electronic ID card, different providers are supported here.
If an Ausweisapp2 or Open eCard app is installed, it is automatically recognized.

If no local application is found, a QR code is displayed.
This must be scanned with a special app.
The authentication process then takes place via the app.
