Cloudflare now lets you attach Access authentication policies directly to a Worker or across an entire account, so every preview URL, custom domain, workers.dev subdomain, and route is behind company login by default—no per-hostname configuration needed. You can scope protection to preview URLs only or all hostnames, and authenticated user identity (email, name, groups) is injected directly into your code without JWT validation.

Why: If your team is deploying AI-generated or vibe-coded Workers apps that may accidentally expose internal data, you can now enforce auth at the account or Worker level instead of trusting each developer to configure it per domain. This removes the gap where adding a new custom domain left a Worker unauthenticated until you manually updated policy.
