## Why Enterprise sign-in needs to keep browser completion separate from credential storage so callers can recheck the active account and configuration before saving a grant. Logout must also prevent an earlier sign-in from restoring credentials, including from another process sharing `CODEX_HOME`. ## What changed - Add enterprise login APIs in `rmcp-client` that return an authorization URL and stage validated credentials for an explicit `commit_if` call. Store grants only in the keyring after rechecking caller authority under the credential lock. - Require a registered client ID, published metadata matching the configured issuer, HTTP loopback callbacks, a refresh token, and a valid OIDC identity assertion. Request `openid` and `offline_access` with `prompt=consent`, and omit MCP resource indicators from authorization and code exchange. - Persist a login generation under the credential lock so logout invalidates pending and staged sign-ins across processes, even when no grant is stored. - Keep credentials and account identifiers out of enterprise error chains and logs, and avoid logging callback payloads when the receiver has closed. ## Testing Add coverage for discovery validation, loopback callbacks, PKCE, staged keyring storage, cancellation, stale attempts, cross-process logout, and error/log privacy. Preserve ordinary MCP OAuth login without a refresh token, and adjust the terminal polling test deadline to include the minimum empty-poll wait.

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"
The standalone installers download from https://releases.openai.com/codex by default and fall back to GitHub Releases if a metadata or asset download is unavailable. To force GitHub Releases, set CODEX_INSTALLER_USE_RELEASES_OPENAI_COM to false (0 and no are also accepted):
curl -fsSL https://chatgpt.com/codex/install.sh | CODEX_INSTALLER_USE_RELEASES_OPENAI_COM=false sh
$env:CODEX_INSTALLER_USE_RELEASES_OPENAI_COM='false'; 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.
