I'm not quite sure if the German implementation is possible without mobile devices (couldn't find anything on that at first glance). the Austrian implementation on the other hand does not require a mobile device, if you want to do it on a pc you just need a fido2 token
I'm not sure either. I've looked at this other document: https://bmi.usercontent.opencode.de/eudi-wallet/eidas-2.0-ar...
It seems to imply that the already existing way of authenticating via eID, which is the auth chip present on our ID cards, will still work, if I read it correctly? I understand OP's link to refer to a new, alternative system, that can be used without the ID card.
But take this with a grain of salt, I'm not very well informed about the whole topic.
I havent looked into the details of either, but what would prevent Germans from using the Austrian implementation?
As strange as it is, but Austria is quite far ahead in terms of eIDAS since we've had Handysignatur for more than a decade. I wouldn't be surprised, if the Germans are planning to support hardware tokens, but haven't had the time yet.
