Also, most smartphones (especially GrapheneOS, iOS, Pixel, etc) are far more secure than desktops/laptops. So also from a security perspective it's better to do banking on a phone.
This has to be some fascinating regional difference, because my personal experiences suggest the opposite. Would you be willing to elaborate ( in general terms/locations if too sensitive )?
I wonder if phone theft specifically hasn't (somewhat) gone down now that most are encrypted and tied to some online account by default. Maybe criminals have heard about this, and they focus on other things.
Where I live, people still carry cash (though not absurd amounts) and credit cards, and I understand that's what most pickpockets are after. Especially since, after covid, the limit for contactless payments has increased.
Burglars recently broke into my parents' house and they left the MacBook and iPads. Most informed thieves probably know that they are bound to an account, can easily be blocked, and there is no use trying to sell them.
I would assume its more and more the case with phones as well. ~10-15 years ago I heard often about smartphones getting stolen out of people's pockets, etc. Not so much anymore.
It means that banks cannot say "desktop is insecure, therefore a mobile app is required for your security". I can manage my own security in a better way.
