I'd say the German government's solution is to just not offer any digital services in the first place. /s

In reality, they have some things moving, but too little, too late:

- Filing taxes has been pretty much digital only (for some sorts of taxes, at least) for a couple of years now. It's certificate based, where you "order" your certificate via snail mail.

- ID cards have a digital authentication function, but I have yet to see any service using it.
