>Which banks do you use? I’m looking to switch away from Chase (which does this).

Do you mean SMS codes or a Chase Bank App?

I have to deal with the former because I auto-delete cookies when I close tabs and use Multi-account containers on Firefox.

I've never been required to install any application (Chase branded or otherwise) on my phone in order to use the Chase website. I'll note that I've been a Chase customer since they acquired Chemical Bank in 1996.

Am I missing something important here? If so, I'd love to hear about it.

Chase allows both SMS and their app to be the 2nd factor; I dislike both of those options and would much rather TOTP
