What actual real life person is going to switch their bank account because TOTP isn't supported?
That's why banks get authentication wrong. Because they are in the business of banking and banking customers do not care about TOTP.

I can't get SMS when I'm traveling which is 95% of my time. It's such an entirely ignorant US-centric view to assume that everyone has a phone, has SMS plans, has cell service at all, etc.
I think many banks might find it a benefit to exclude customers who don't have cellphones or SMS.
