# Introduction

> Device attestation and intelligence for iOS developers

Grantiva verifies devices using Apple's App Attest API, issues JWT tokens with device intelligence, and provides risk scoring. No client-side API keys needed — your app is identified automatically by Bundle ID and Team ID.

## How it works

1. **Your app requests a challenge** from the Grantiva server
2. **App Attest creates an attestation** on the device using Apple's framework
3. **Grantiva validates the attestation** and scores the device
4. **A signed JWT token is returned** with device intelligence and custom claims
5. **Your backend verifies the token** to make trust decisions

No API keys are sent from the client. The server identifies your app by its Bundle ID and Team ID, which are sent automatically by the SDK.
