We strongly oppose the Unified Attestation initiative and call for app developers supporting privacy, security and freedom on mobile to avoid it. Companies selling phones should not be deciding which operating systems people are allowed to use for apps.

Unified Attestation

Unified Attestation is a free, open-source alternative to Google Play Integrity with offline verification and simple app + server integration.

@GrapheneOS
Is this (unified attestation) an analog of whatever it is that google does in apps that ends up with things like banking apps needing google services? Or am I thinking of something completely different?
@tirohia It's another way for apps to forbid using arbitrary operating systems and instead only allow specific ones. In Google's case via the Play Integrity API that means permitting only operating systems licensing Google Mobile Services. That includes mostly insecure devices failing to provide patches. In this case it's a way to allow a specific set of operating systems developed in Europe which are failing to provide basic privacy/security patches and protections. It's actually anti-security.
