n8n with ChatGPT sign-in

Unofficial n8n option

Starts here: Your self-hosted n8n
Authentication: Your ChatGPT/Codex sign-in stays in a private sidecar volume
Connection: Private Docker network with no host port
Ends here: Supported models through the unofficial openai-oauth sidecar

This option is unofficial, private and policy-uncertain. It does not turn ChatGPT sign-in into a Platform API key.

Hosted chat

Hosted chat is off.

Relmio turned off chat and ChatGPT sign-in on this site while it applies to OpenAI for access. For now, sign-in works only in the local wizard on your own computer.

Relmio never used an OpenAI Platform API key for ChatGPT sign-in.

Install the local wizard

Signed in here before?

If you used the hosted chat, an encrypted copy of your sign-in may still be saved in this browser.

This does not revoke access at OpenAI. To end it there, sign out of your other sessions in ChatGPT under Settings > Security and login.

Safety boundary

The n8n bridge stays private.

Setup for n8n runs in the local wizard on your own computer.
