I use a hardware TAN generator which I could use with any browser. I use my banking app (which works on LineageOS so will presumably work on GrapheneOS) just to generate TAN for authentication. My banking cards support NFC.
The day my Pixel 9 Pro XL came to my door, I unlocked the bootloader and rooted it. Yet, somehow, all of my banking apps (Venmo, Fidelity NB, a national bank, and a local CU) still manage to work just fine.
I require my banking app to work.
you can use the bank website
How will that work exactly? Do you carry your TANs or secure token around all the time?

no different than your banking app. most websites have a remember me option
Skill issue?
