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.
US, Virginia. Funny, I tend to assume Europe has this stuff better figured out.
EU Nations who are familiar with computers like Sweden and Estonia did.
Germany likes to think that they belong to cabinets and powered with internal combustion engines. Internet was a new land in 2013. So every user-friendly feature has to be shoved into Germany's throat by EU (especially banks and insurance). The usual reaction from German companies is to wait until the last moment and then hire a law / consultancy firm to implement required changes as badly as possible.
Try Targobank, it works for me.
