Who will implement this?
My government does this actually.
Yes, and banks when you wanna activate online banking. Arguably, then it’s just for registering, and logging in then works differently.
Governments and banks love this, but I’ve even seen it with phone companies with e-sims. I quickly needed a new phone subscription, so I considered an e-sim, because I figured you could activate it by scanning the QR code from the screen. But no, they will mail me a piece of plastic with the QR code on it. So I went with a regular sim instead.
