If apps don’t do anything weird, this stuff should work automatically. Most of my issues with password managers stem from apps that decide to throw all standard components and APIs away and redesign the concept of “text input” from the ground up.

I believe banks do this intentionally so malware can’t automatically enter input without additional effort. The same bullshit sometimes also messes with browser password managers, like not accepting the autofill or treating the input field as empty unless you typed something into it.
