## Summary External auth had two paths: provider-command credentials were resolved through `ExternalAuth`, while app-provided ChatGPT credentials were installed separately and only used the provider for refresh. `ExternalAuth` also declared an auth mode independently from the `CodexAuth` value it returned, so the declaration and credentials could disagree. This change makes the provider-owned `CodexAuth` authoritative for initial resolution, credential kind, and refresh. - remove `ExternalAuth::auth_mode` and require providers to return their current auth from `resolve` - route external auth registration, resolution, and unauthorized refresh through `AuthManager::set_external_auth` - keep the last resolved credential with its provider so synchronous consumers and unauthorized recovery observe the credential's actual mode - make the app-server bridge own both initial and refreshed ChatGPT credentials, and detach it on logout - keep model listing free of auth-refresh side effects, including in offline mode Provider-command auth still follows its configured cache interval. App-provided ChatGPT auth still asks the parent app once after a `401` and retries the request once. Stacked on #31355. ## Testing - `just test -p codex-login` - `just test -p codex-models-manager` - focused `codex-app-server` tests for external login/logout, unauthorized refresh, and workspace mismatch
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.
