> you cannot log in to your bank account on your laptop/computer without using your phone's banking app
Where is this?
I have lots of bank accounts, probably more than most people. Three local credit unions, Fidelity, Schwab, Chase, BofA, Citibank, Barclays, two local area banks, and two international banks. Plus a few lesser known ones for 401k/IRA accounts.
I have never installed any bank phone app. I do all my bank interactions from my desktop via Firefox.
