On Mac, Codex is a separate app from ChatGPT, but the mobile integration feature is currently offered within the existing ChatGPT app for iPhone and Android.
The setup is simple. First, update both the Codex Mac app and the ChatGPT mobile app. Then, in the Mac app interface, select the newly added Codex mobile section. Scan the QR code displayed on the screen with your phone to complete the setup.
Once connected, the mobile app will load the real-time status of your Mac where Codex is running. Users can continue working on chats or projects that were in progress on their desktop, receive notifications when Codex completes a task or needs input, and even send messages from their phone to start new tasks.
OpenAI emphasized that since Codex needs to access files, apps, and browsers on the desktop to complete tasks sent from a mobile phone, users should only pair devices they own and trust.
They also announced that remote access support for Windows Codex will be available soon.
