I got a list of codes when i opened my first online bank account in the early 2000's. In between there was a special key-generator given to each customer, that was abandoned about 10 years ago. (edit: it was the RSA SecurID's mentioned in this thread) Since then we've got apps that need to be activated using a letter with a special qr-code, as well as the bank account-number (username) & password another qr-code from the website. I assume it generates a private key in the app which will not be transferred to a new device (but maybe somehow is). You need to login using your account-number (username) and password, after that you have to open the app (login with face-scan) scan a qr-code and enter the generated code. Getting a printed out card or page with something on it to verify your identity seems like 20 years tech to me.
