## Summary When using device-code login with a custom issuer (`--experimental_issuer`), Codex correctly uses that issuer for the auth flow — but the **terminal prompt still told users to open the default OpenAI device URL** (`https://auth.openai.com/codex/device`). That’s confusing and can send users to the **wrong domain** (especially for enterprise/staging issuers). This PR updates the prompt (and related URLs) to consistently use the configured issuer. 🎯 --- ## 🔧 What changed * 🔗 **Device auth prompt link** now uses the configured issuer (instead of a hard-coded OpenAI URL) * 🧭 **Redirect callback URL** is derived from the same issuer for consistency * 🧼 Minor cleanup: normalize the issuer base URL once and reuse it (avoids formatting quirks like trailing `/`) --- ## 🧪 Repro + Before/After ### ▶️ Command ```bash codex login --device-auth --experimental_issuer https://auth.example.com ``` ### ❌ Before (wrong link shown) ```text 1. Open this link in your browser and sign in to your account https://auth.openai.com/codex/device ``` ### ✅ After (correct link shown) ```text 1. Open this link in your browser and sign in to your account https://auth.example.com/codex/device ``` Full example output (same as before, but with the correct URL): ```text Welcome to Codex [v0.72.0] OpenAI's command-line coding agent Follow these steps to sign in with ChatGPT using device code authorization: 1. Open this link in your browser and sign in to your account https://auth.example.com/codex/device 2. Enter this one-time code (expires in 15 minutes) BUT6-0M8K4 Device codes are a common phishing target. Never share this code. ``` --- ## ✅ Test plan * 🟦 `codex login --device-auth` (default issuer): output remains unchanged * 🟩 `codex login --device-auth --experimental_issuer https://auth.example.com`: * prompt link points to the issuer ✅ * callback URL is derived from the same issuer ✅ * no double slashes / mismatched domains ✅ Co-authored-by: Eric Traut <etraut@openai.com> |

npm i -g @openai/codex
or brew install --cask codex
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 are looking for the cloud-based agent from OpenAI, Codex Web, go to chatgpt.com/codex.
Quickstart
Installing and running Codex CLI
Install globally with your preferred package manager:
# 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, Team, Edu, or Enterprise plan. Learn more about what's included in your ChatGPT plan.
You can also use Codex with an API key, but this requires additional setup.
