Speaking for Lithuania - we have something like 6 or 7 digital ID forms and until like last year or so - they all sucked, i.e.:
* Using your bank to login - well if you left country you generally close your bank.
* SIM card auth (similar to SMS, you get a code on your phone) - most popular, except same as above + doesn't work with eSIM.
* Chip card - requires reader, unclear software and certificates on card expire after 2 years which makes it useless if you moved abroad.
* Smart Id - scans your passport, does face scan and stays on your phone - pretty convenient, but turns out there are multiple levels of auth and this particular one isn't that useful...
* Contactless - the holy grail that's only been implemented recently - scan your id card/ passport using phone. I've only used it once, did require some esoteric software, but seems like a step in the right direction.
Bonus: e-gov forms actually predate mobile era. They have been built so long that you can forget trying to fill them on your phone. And if you do get to fill them, you'll most likely receive email that you need to come into the office for 'verification' which pretty much defeats entire system.
