They once identify you from your driver's license, government id card or passport. After that you for example link your smart phone to you, and you use their app when you identify.
You can also use mobile carriers, they send a push notification directly to you phone+sim. Not sure what protocol they use here, because it opens up an UI which is plain android, and asks pin.
Everything relays on chain of trust that since one service has identified you, the next can trust too. Plus there is MFA to verify that you actually made the identification request.
The initial argument was ‘sending is to anyone is insane’ but that’s what you do with the bank. Yes it’s only once - but that’s the same as the other systems we are taking about here.
Interesting, so your answer to identity authentication is it is it shouldn’t ultimately be done to do remotely and that everyone needs to queue at the counter.
The other bank and other mobile provider identifies you through the another one. I am able to identify through two different banks and mobile provider, and have not in 15 years done it onprem. I do strong digital authentication generally once or twice a week.
Edit: last time was actually when I took house mortgage 13 years ago, and switched bank. Not really a issue to show ID onprem when talking 200k€.
So, to be clear - if you ever need to renew government documentation or get access to government systems (benefits or taxes), the government doesn’t ask to see government ID - it outsources that to bank procedures from n years ago?
Practical sense yes, I accessed my tax info today, and strongly authenticated through my mobile provider. It took me 2 seconds and there was MFA included in the process.
