Abrar Ahmed 7cf6f1c723 Use issuer URL in device auth prompt link (#7858)
## 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:

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

or brew install --cask codex

Codex CLI is a coding agent from OpenAI that runs locally on your computer.

Codex CLI splash


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
  • Linux
    • x86_64: codex-x86_64-unknown-linux-musl.tar.gz
    • arm64: codex-aarch64-unknown-linux-musl.tar.gz

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.
