## Summary This PR moves Codex backend request authentication from direct bearer-token handling to `AuthProvider`. The new `codex-auth-provider` crate defines the shared request-auth trait. `CodexAuth::provider()` returns a provider that can apply all headers needed for the selected auth mode. This lets ChatGPT token auth and AgentIdentity auth share the same callsite path: - ChatGPT token auth applies bearer auth plus account/FedRAMP headers where needed. - AgentIdentity auth applies AgentAssertion plus account/FedRAMP headers where needed. Reference old stack: https://github.com/openai/codex/pull/17387/changes ## Callsite Migration | Area | Change | | --- | --- | | backend-client | accepts an `AuthProvider` instead of a raw token/header | | chatgpt client/connectors | applies auth through `CodexAuth::provider()` | | cloud tasks | keeps Codex-backend gating, applies auth through provider | | cloud requirements | uses Codex-backend auth checks and provider headers | | app-server remote control | applies provider headers for backend calls | | MCP Apps/connectors | gates on `uses_codex_backend()` and keys caches from generic account getters | | model refresh | treats AgentIdentity as Codex-backend auth | | OpenAI file upload path | rejects non-Codex-backend auth before applying headers | | core client setup | keeps model-provider auth flow and allows AgentIdentity through provider-backed OpenAI auth | ## Stack 1. https://github.com/openai/codex/pull/18757: full revert 2. https://github.com/openai/codex/pull/18871: isolated Agent Identity crate 3. https://github.com/openai/codex/pull/18785: explicit AgentIdentity auth mode and startup task allocation 4. This PR: migrate Codex backend auth callsites through AuthProvider 5. https://github.com/openai/codex/pull/18904: accept AgentIdentity JWTs and load `CODEX_AGENT_IDENTITY` ## Testing Tests: targeted Rust checks, cargo-shear, Bazel lock check, and CI.

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 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
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, Business, 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.
