We have that in Sweden too. As an expat it's a complete nightmare for me from day one. Getting my bank to successfully issue it was impossible.
First, in the days before mobile bank-id, they sent windows-only hardware as I recall. Then came the days of letters/cards/hardware getting lost in the mail.
I gave up on it in the end. I have multiple things (banking-wise) I no longer have online access to because of it.
If you're going to make one system to rule them all you need to make sure the logistics actually work.
(3 years ago I moved to Norway)
It took me about a month to get into the system, but once I had my national ID it took about a week for my MFA dongle to arrive. After that It has been a great experience.
