Where are you from? I live in Germany. I use ING and DKB as my banks. Both of the banks require a Play Integrity-checked app as their default 2FA.In the past I used Sparkasse and Commerzbank. They too required a PI-approved app.
As an alternative you can order a code generator but for DKB that requires a paid debit-card. ING disables the phone app if you use a code generator. You cannot have multiple 2FA.
