## Why `codex-backend` now authenticates remote-control server websocket connections with short-lived server tokens instead of the user's ChatGPT access token. `app-server` needs to mint and refresh those server tokens without persisting them, so a restart can reconnect from durable enrollment identity while keeping the bearer token memory-only. ## What Changed Updated the remote-control transport to consume `remote_control_token` and `expires_at` from server enroll responses and added `/server/refresh` support for persisted enrollments or expiring cached tokens. Websocket handshakes now send `Authorization: Bearer <remote_control_token>` with the existing server identity headers, and no longer send the ChatGPT bearer token or `chatgpt-account-id` on that websocket path. The in-memory enrollment state now owns the ephemeral server token cache, while SQLite still persists only `server_id`, `environment_id`, and `server_name`. Websocket `401`/`403` clears only the cached token for refresh on reconnect; websocket or refresh `404` clears stale persisted enrollment and re-enrolls. Response body previews redact `remote_control_token` before surfacing parse errors. ## Verification - `just test -p codex-app-server-transport` - Manual prod smoke with an isolated `CODEX_HOME`: `codex remote-control --json -c 'chatgpt_base_url="https://chatgpt.com/backend-api"'` reached `status:"connected"` with `environmentId:"env_i_6a17d9f1d764832986da2e80f4554f1b"`.
Codex CLI is a coding agent from OpenAI that runs locally on your computer.
If you want Codex in your code editor (VS Code, Cursor, Windsurf), install in your IDE.
If you want the desktop app experience, run
codex app or visit the Codex App page.
If you are looking for the cloud-based agent from OpenAI, Codex Web, go to chatgpt.com/codex.
Quickstart
Installing and running Codex CLI
Run the following on Mac or Linux to install Codex CLI:
curl -fsSL https://chatgpt.com/codex/install.sh | sh
Run the following on Windows to install Codex CLI:
powershell -ExecutionPolicy ByPass -c "irm https://chatgpt.com/codex/install.ps1 | iex"
Codex CLI can also be installed via the following package managers:
# Install using npm
npm install -g @openai/codex
# Install using Homebrew
brew install --cask codex
Then simply run codex to get started.
You can also go to the latest GitHub Release and download the appropriate binary for your platform.
Each GitHub Release contains many executables, but in practice, you likely want one of these:
- macOS
- Apple Silicon/arm64:
codex-aarch64-apple-darwin.tar.gz - x86_64 (older Mac hardware):
codex-x86_64-apple-darwin.tar.gz
- Apple Silicon/arm64:
- Linux
- x86_64:
codex-x86_64-unknown-linux-musl.tar.gz - arm64:
codex-aarch64-unknown-linux-musl.tar.gz
- x86_64:
Each archive contains a single entry with the platform baked into the name (e.g., codex-x86_64-unknown-linux-musl), so you likely want to rename it to codex after extracting it.
Using Codex with your ChatGPT plan
Run codex and select Sign in with ChatGPT. We recommend signing into your ChatGPT account to use Codex as part of your Plus, Pro, Business, Edu, or Enterprise plan. Learn more about what's included in your ChatGPT plan.
