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.
Some banks require the app to be used as second factor to log into their website.
Can you work around it with magisk like rooted stock android? I bought my pixel specifically for graphene but google pay is the main thing preventing me from switching
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.
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.
