I use it as it's included in GrapheneOS. But highly recommend for every supported device.Has anyone used https://play.google.com/store/apps/details?id=app.attestation.auditor?
Do you keep it installed?
Hardware-based attestation / intrusion detection app for Android devices. It provides both local verification with another Android device via QR codes and optional scheduled server-based verification with support for alert emails. It uses hardware-backed keys and attestation support as the foundation and chains trust to the app for software checks.
