Verify device legitimacy and app integrity using DeviceCheck (DCDevice per-device bits) and App Attest (DCAppAttestService key generation, attestation, and assertion flows). Use when implementing fraud prevention, detecting compromised devices, validating app authenticity with Apple's servers, protecting sensitive API endpoints with attested requests, or adding device verification to your backend architecture.

Verify that requests to your server come from a genuine Apple device running your unmodified app. DeviceCheck provides per-device bits for simple flags (e.g., "claimed promo offer"). App Attest uses Secure Enclave keys and Apple attestation to cryptographically prove app legitimacy on each request.
DCDevice generates a unique, ephemeral token that identifies a device. The token is sent to your server, which then communicates with Apple's servers to read or set two per-device bits. Available on iOS 11+.
Your server uses the device token to call Apple's DeviceCheck API endpoints:
