Even GrapheneOS is not as insane to suggest ebanking should be restricted to locked down platforms.
EU should ban banks from requiring hardware attestation and other "security" excuses to refuse serving people.
Hardware attestation verifies that the phone and the OS its running on are real and not an emulator or a fake malware laced version.
It ensures that you don't get your bank account stolen by a fake ROM with an infostealer inside.
No, it verifies that the phone is running an approved OS. If the app developer does not add your OS' keys it will fail. This included GrapheneOS.
We have been web banking for decades on platforms without hardware attestation. The potential for anti-competitiveness abuse is not worth it.
It also does not protect the user. If your system is actually compromised they can simply replace the app, not allow it to run etc. I don't see how it protects the user if they chose to run an emulator, what exactly is the threat to the user there?
If someone injects malware into your GrapheneOS image then the attestation won't pass. That is how it works.
