the problem in my case is that the authentication for the banks website requires an app, and that app doesn't work. i am locked out of online banking for that bank because of it. (they also have a windows app that i could not yet get to work on linux/wine)
Find a new bank. Mine has another problem, so behind they don't support mfa beyond a symantec program I've not heard of before. I don't use it, but can't use my yubikeys either.
