App attestation

App attestation is used to verify that a client app is genuine and hasn’t been tampered with. For example, Google can certify that a user is running an unmodified version of an Android app installed from the Google Play Store.

This form of attestation can be a signal in client reputation scoring. In particular, it can be used to tell whether a new client, for which there is no reputation data, is likely to comply with rate limits.

App attestation is only supported on Android and Apple devices, but not all devices support it.
