I can sign in to DigID without using my phone, except sometimes with an SMS verification code. (Of course they want to, and should, phase that out. Hopefully that won't be replaced by app store dependence.)
What alternative is there, today, that would allow securely doing this without an app store dependency?
Only a few EU countries have rolled out NFC-based eID functionality (as only physical ICAO-based ID verification via NFC is a mandatory part of the EU ID card standard); those are the only ones with a viable path forward in the short term.
