Access Codex remotely from mobile apps
TL;DR
Codex is now available in preview on iOS and Android, allowing users to connect to a Mac host. You can review terminal output, approve actions, and manage active investigations while away from your desktop.
## What changed Codex remote access entered preview on May 14, 2026. Users can now connect the ChatGPT iOS or Android app to a Mac host running the Codex desktop app. From the phone they can start threads, approve actions, review terminal output, diffs, screenshots, and test results, then switch hosts without returning to the desk.
The host must stay awake and online. Setup begins in the Codex app on macOS, continues by scanning a QR code in ChatGPT, and works across Free, Go, Plus, and Pro plans in supported regions.
## Why it matters Vibe Builders who keep Codex running long investigations or agent loops gain the ability to steer work from anywhere. The change reduces the friction of being tied to one machine during multi-hour tasks.
It pressures desktop-only automation tools that lack mobile oversight. The bet is that builders will accept always-on Mac hosts in exchange for continuous control rather than batching work until they return to their desk.
## How to use it Update the ChatGPT mobile app and the Codex macOS app. Open the Codex app on the host, enable remote connections, then scan the QR code shown inside ChatGPT. Keep the Mac awake and connected for the session to persist.
Remote access loads live project context, approvals, plugins, and terminal output directly from the host. Documentation sits at developers.openai.com/codex/remote-connections.
## Watch for Confirm the bet if mobile sessions show stable context and low latency over several hours. It breaks if hosts drop connections frequently or if approval flows feel slower than desktop. Expect OpenAI to add Windows hosts or background push notifications next.
Harsh’s take
A solo operator now needs a spare Mac that stays powered on and online. That adds electricity cost, security exposure, and one more device to maintain. The mobile layer only works while the host runs Codex, so the real constraint has not moved.
Trade-off is clear: you gain steering from the couch but lose the simplicity of a single laptop that sleeps when you do. Most builders will discover the extra machine becomes the new bottleneck.
Do this now: test one active Codex thread from your phone for a full workday and measure how often the host connection drops before you commit to keeping a second computer running.
