> I know banking apps are the typical example, but I've always wondered why

My bank uses the app for 2FA, and that became a sort of a standard in Brazil, AFAIK. Mine at least gave me the option of using an RSA SecurID or sth alike when I asked, but I don't know how much it would cost me.

My stock broker on the other hand does 2FA exclusively on mobile (and only Android and iOS). The same for the health insurer.

My car insurer didn't force me to so far, which I find strange, given their interest in tracking my location and speed.

These were some of the major factors leading me to give up on using a feature phone when I tried, a few years ago. It was a good experience, especially at those times of pandemics and political instability, but the inconveniences were many.
