## Codex on mobile advantages

- **Start tasks from your phone:** Choose Cloud and an environment, or a connected computer and project, then describe the task.
- **Guide work as it happens:** Open a task, follow its progress, and send new instructions without returning to your desk.
- **Approve requested actions:** Review requested commands and actions before Codex continues on your connected computer.
- **Review the result:** Inspect responses, changed files, diffs, and test results, then decide what happens next.

## Get started on mobile

Connect your computer, approve access, and start your first task.

1. **Start setup on your computer.** Open the ChatGPT desktop app on your Mac or Windows PC. Go to **Settings** > **Connections** > **Control this Mac or PC** and select **Set up** or **Add**. Approve remote access and complete any requested verification.
2. **Scan the QR code.** Scan the code with your phone, sign in to the same ChatGPT account and workspace, and approve the connection. Only connect devices you own and trust.
3. **Start working from your phone.** In the ChatGPT mobile app for iOS, open **Codex** to choose your connected computer and start or continue a task. If your mobile app still shows Remote, open it instead. Keep your computer awake and online.
