@forthy42 @pojntfx I guess the (not-so-easy) backup method would be to acquire eIDs from multiple member states (the Estonian e-residence would probably be one of the easier additional ones to get) and then rely on the cross-border mutual recognition which I believe EIDAS guarantees? I hope the German wallet will work with other European eIDs?
Would this address the issue if one still needs some approved device with Google Play Services and some Google profile?
