Codex Phone Connect

Pair Codex Desktop with the ChatGPT mobile app so you can send tasks to Codex from your phone.

Keep these prerequisites minimal:

  • Codex Desktop is already installed and can be opened.
  • ChatGPT is installed on your phone, and the same account is signed in on both devices.
  • If you want only the desktop app to use a proxy, your usual proxy tool is already set up on Windows.
  1. Open settings in CC Switch
  2. Enable the Codex-related enhancements
  3. Open the Codex Desktop sign-in screen
  4. Finish signing in or registering
  5. Open Remote on the phone
  6. Confirm you are already signed in on desktop
  7. Choose I have a pairing code
  8. Scan the pairing code shown on the desktop
  9. Wait for pairing to complete
  10. Confirm the desktop device appears
  11. Enter chat and start using it

Advanced: Route only Codex Desktop through a proxy

Section titled “Advanced: Route only Codex Desktop through a proxy”

On Windows, switch your usual proxy tool to rule mode so only Codex Desktop hits the local HTTP proxy while other apps stay as close to normal as possible.

Then set the current user’s environment variables to:

  • HTTP_PROXY = http://127.0.0.1:<proxy-port>
  • HTTPS_PROXY = http://127.0.0.1:<proxy-port>

Fully quit Codex Desktop, then open it again.

If you use global routing or TUN mode, QQ / WeChat images can sometimes be affected. Rule mode plus environment variables usually reduces that impact. The goal is to change only Codex Desktop’s outbound path, not the whole machine’s.

To verify, send one Codex request first, then check whether QQ / WeChat images load normally; if there is still obvious impact, recheck rule mode and the <proxy-port> value.
