Getting Started

Getting started

This page takes you from nothing to a working multi-account setup: install codex-switch, add accounts, and pick the best one before a Codex session.

Requirements

• OpenAI Codex CLI installed, plus at least one ChatGPT account that can log in to Codex.
• Codex must use its file credential store, because codex-switch works by atomically replacing $CODEX_HOME/auth.json. If needed, add this to $CODEX_HOME/config.toml (normally ~/.codex/config.toml):

cli_auth_credentials_store = "file"

Explicit keyring, auto, and ephemeral stores are rejected. A managed Codex configuration with forced_login_method = "api" is also incompatible, because codex-switch manages ChatGPT login profiles. In both cases codex-switch stops with an actionable error instead of modifying authentication state.

Install

macOS / Linux:

curl -fsSL https://github.com/xjoker/codex-switch/releases/latest/download/install.sh | bash

This installs to the user-owned $HOME/.local/bin and configures PATH for zsh, bash, and fish; other shells receive a manual PATH instruction. An older direct install under /usr/local/bin is migrated once: the new user binary is installed first, then the installer removes the old copy with one elevated operation when required. Administrators can explicitly keep a system-wide install with --system; system installs may require sudo for later updates.

If the installer says Installing to /usr/local/bin (requires sudo) without an explicit --system, stop it: that is the retired script from the repository's old master branch. Use the Release URL above.

Windows PowerShell:

irm https://github.com/xjoker/codex-switch/releases/latest/download/install.ps1 | iex

Windows installs under %LOCALAPPDATA%\Programs\codex-switch and updates the user PATH.

Homebrew (macOS / Linux):

brew install xjoker/tap/codex-switch

Homebrew distributes stable releases only and keeps ownership of its binary; update it with brew upgrade xjoker/tap/codex-switch, not with self-update.

Verify the installation:

codex-switch --version

Add your first account

codex-switch login work

login opens a browser PKCE flow; the alias (work) is optional and can be renamed later. On a headless machine, use the device-code flow instead:

codex-switch login --device server

If you already have auth.json backups, import a file or scan a whole directory. Imports are parsed, identity-checked, validated against the usage service, deduplicated by account identity, and assigned collision-free aliases:

codex-switch import ~/auth-backups

codex-switch also notices logins performed outside of it: when the live auth.json contains an account it does not track (for example after a plain codex login), an interactive run offers to save it as a profile.

Inspect quota and pick an account

codex-switch list        # accounts, quota, availability
codex-switch tui         # interactive dashboard
codex-switch use         # switch to the best eligible account
codex-switch launch      # select, start Codex, restore auth afterwards

use without an alias ranks all accounts with the adaptive scoring algorithm; use <alias> switches explicitly. Codex reads authentication at startup, so restart Codex after a manual switch — or use launch, which handles staging and restoration for you.

Where your data lives

Saved profiles, cache, configuration, and daemon state default to ~/.codex-switch (%USERPROFILE%\.codex-switch on Windows). The live Codex file stays at $CODEX_HOME/auth.json. See Configuration for every path and setting.

Never share profile files, auth.json, tokens, proxy credentials, or unredacted --debug output.

Next steps

• Look up exact commands and TUI shortcuts in the Command reference.
