Codex Remote Control rejects verified MFA login on Windows

Hi OpenAI Support,

I am unable to enable Codex Remote Control in the ChatGPT Windows app. The app displays “Couldn’t update remote
control availability.”

My goal is to continue an existing Codex CLI session running in Warp on this Windows PC through ChatGPT Remote on
my Android phone.

Account and environment:

• Account email: available privately on request
• Plan: ChatGPT Max
• Workspace: Personal account
• ChatGPT desktop app: 26.825.6671.0
• Codex CLI: 0.151.0
• Windows: 10.0.26200
• Phone: Samsung SM-S928U

I confirmed that the desktop app and phone use the same ChatGPT account and workspace. I restarted the app,
completed multiple fresh logins, enabled MFA, completed password plus phone-push MFA, completed password plus
email-code MFA, and added a 1Password passkey.

The issued credentials record successful MFA, but Remote enrollment still returns HTTP 403 with “Multi-factor
authentication required.”

Endpoint:

POST /backend-api/wham/remote/control/server/enroll

Recent failures:

• August 31, 2026 at 00:59:09 UTC, request ID: 42dceaab-539e-464d-9f8d-79a9c20b3624
• August 31, 2026 at 01:11:54 UTC, request ID: 72d50507-1bfd-4b2f-88e9-2c83d9a48c3e

Could you please review or reset the Remote Control enrollment and MFA state for this account and advise how I can
complete the Windows and Android pairing?

Thank you.

The report identifies the POST /backend-api/wham/remote/control/server/enroll endpoint and two request IDs associated with HTTP 403 responses. Start by tracing the enrollment and MFA handling for this endpoint, then reproduce the Windows login and Android pairing flow; done means verified MFA permits enrollment and Remote Control pairing succeeds.
