Secure Banks that are compatible with grapheneOS

USS-Privacy

I had a tough time finding any banks that allowed for using ente authenticator and worked with grapheneOS. The one that seemed to work for me was SOFI bank. The con is theres no in person banks nearby and it does not allow using yubi keys or anything similar. SOFI is a USA bank. Feel free to post other banks that are good here:

From a privacy standpoint, this can be a tall ask - IMO, anyway..threat models notwithstanding. You may not receive as many replies as you would another query.

But I believe most banks work fine on GOS, itself. There is a thread discussing, IIRC. You can use the search feature here and it should be the most active in the results.

Edit/add: As for using any auth app, the vast majority of banks will not allow this. They prefer to use good ol' SMS code auth because you know R&D is important in that industry (italicized for sarcasm).

If you are in the EU, keep in mind that TOTP/HOTP it is not PSD2-compliant, so it cannot be used to authorize payments. You might find a bank that lets you use your authenticator to log in, but that seems very unlikely: they need their own app (or SMS) to authorize payments, so adding a second 2FA stack would just mean more stuff to maintain.
