We have something vaguely similar with "BankID" in Norway. It's a bank issued digital ID that submits a 2FA to your phone (not through SMS, but through some other system that takes over the whole screen - not sure what it is).
It's usable for almost all government agencies or official stuff online here, but I haven't seen anyone use it for third party auth as it costs roughly 10 cents per login for the service using it.
