## Summary Auth loading used to expose synchronous construction helpers in several places even though some auth sources now need async work. This PR makes the auth-loading surface async and updates the callers to await it. This is intentionally only plumbing. It does not change how AgentIdentity tokens are decoded, how task runtime ids are allocated, or how JWT signatures are verified. ## Stack 1. **This PR:** [refactor: make auth loading async](https://github.com/openai/codex/pull/19762) 2. [refactor: load AgentIdentity runtime eagerly](https://github.com/openai/codex/pull/19763) 3. [feat: verify AgentIdentity JWTs with JWKS](https://github.com/openai/codex/pull/19764) ## Important call sites | Area | Change | | --- | --- | | `codex-login` auth loading | `CodexAuth` and `AuthManager` construction paths now await auth loading. | | app-server startup | Auth manager construction is awaited during initialization. | | CLI/TUI/exec/MCP/chatgpt callers | Existing auth-loading calls now await the same behavior. | | cloud requirements storage loader | The loader becomes async so it can share the same auth construction path. | | auth tests | Tests that load auth now run in async contexts. | ## Testing Tests: targeted Rust auth test compilation, formatter, scoped Clippy fix, and Bazel lock check.
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.
