ChatGPT iOS 1.2026.146 adds optional Face ID / passcode lock for Codex

What this changes for operators

• An operator running Codex on iOS can now require Face ID or a passcode to open Codex, adding a device-level authority gate that did not exist before.
• It is optional, so the operator decision is whether to enable it as policy for mobile-deployed Codex access.
• Verification path: update to 1.2026.146, enable the lock, confirm Codex requires biometric/passcode on foreground before trusting mobile as an access surface.
