More specifically, Play Integrity API will fail on the Play Service integrity check.
If I recall correctly, this is why Google Pay won’t work on GrapheneOS.
Can you work around it with magisk like stock android? I bought my pixel specifically for graphene but google pay is the main thing preventing me from switching
I’m currently getting MEETS_DEVICE_INTREGRITY with play integrity fix, which is enough for Google Pay to work. The only thing that I haven’t been able to do is drive for Uber or use RCS oddly enough. RCS happened to fix itself about a month ago as well.
As far as I’m aware, there are no work-arounds that allow for circumventing the Play Integrity API. Probably because you cannot avoid the involvement of a Google backend API that is accessed by the app’s backend.
It works like this:
Play Services hands a token to the app, the app sends it to the app backend, and then the app backend lets a Google backend verify the token, which results in a verdict. You cannot manipulate the token.
Both true statements. The banking apps that don’t work aren’t because google wallet doesn’t work, but because they use the same trust policies that Wallet requires in order to run (which GrapheneOS cannot meet because its not a “trusted” OS, per Google)
<end of list>
Some banking apps allegedly don’t work but i have never encountered one. If your bank has a mobile accessible website, it’s basically a non-issue.

You cannot root grapheneos, so the answer is no. That method does work on other rom’s like lineage.
Last time I checked, it was broken for years already. It’s been a while though. edit: Confirmed: https://xdaforums.com/t/module-play-integrity-fix-safetynet-fix.4607985/ Only basic/device attestation is working.

google wallet is not required to be tied to any bank accounts, and US does not even support NFC within banking apps.
