@5am I know this is not what you're asking, but I just want to say anyway, for anyone in the situation you describe: please tell your bank that they need to provide better solutions than whatever proprietary app they have now, because it is not working for you. You can argue this based on security and privacy. You are their customer, they should listen to you. They may not listen because you are a minority, but at least they cannot get away with saying that they have not had any complaints.
@eliasr Yes, it's a good point. It's definitely worth speaking up. I used to do this with my previous bank because they were increasingly pushing people towards their app and away from the card reader-type devices, which people without newer smartphones must rely on to do any online banking. The particular issue I had was that their app just wouldn't work on LineageOS. It would launch but I could never complete the registration.
