Verify Apple devices with no installed software

What this post added

This post introduces support for Private Access Tokens within Cloudflare Access. This allows security teams to verify the health and integrity of a user's device, specifically Apple devices in this initial rollout, without requiring any software installation on the client. It leverages the Privacy Pass Protocol and involves an Origin (Cloudflare), Client (user's device), Attester (Apple), and Issuer (Cloudflare) to issue anonymous, unforgeable tokens that attest to device health attributes like OS version and jailbreak status.
