Using your devices as the key to your apps

This post details the implementation of mutual TLS (mTLS) authentication with Cloudflare Access. It covers generating a Root CA using `cfssl`, configuring it in Cloudflare Access, and creating an Access policy to enforce client certificate validation. The process of generating a client certificate and converting it to PKCS #12 format for iPhone deployment is also described, enabling device-based authentication for a prototype web application.
