Multi-account auth: OpenAI in one app

CodexUse supports multiple OpenAI accounts in a single desktop app. Sign in once per account, then switch between them without re-authentication.

OpenAI-only: CodexUse v2 works with OpenAI Codex CLI accounts only (no other providers).

Why multi-account matters

No API keys needed: CodexUse uses the same OAuth flow as the official CLI. Your credentials are stored locally by default. Pro Cloud Sync (opt-in, manual) syncs profile credentials to CodexUse services.

Supported accounts and models

Account Auth method Available models
OpenAI account OpenAI OAuth GPT-5.3-Codex, GPT-5.2-Codex, GPT-5.1-Codex-Max, GPT-5.1-Codex-Mini, GPT-5.2

Setting up your first profile

  1. Open CodexUse on macOS or Linux.
  2. Click the + button to add a new profile.
  3. Complete the OpenAI OAuth flow in your browser. CodexUse stores the token locally.
  4. Name your profile (for example, "Work" or "Personal").

Adding more accounts

Repeat the steps above for each OpenAI account you want to use. Each profile is independent.

Switching between accounts

From the window

Use the profile cards in the Profiles view or the quick switcher to pick a profile. The switch is quick, no browser needed.

From the system tray

Use the CodexUse tray menu to switch profiles. Each entry shows the profile name so you know which account will run.

Rate limits across accounts

CodexUse Pro shows rate limit usage per profile. When one account approaches its threshold, you can:

CLI bundling explained

CodexUse bundles the Codex CLI so you do not need to install it separately. Updates to CodexUse include CLI updates, so you get compatible versions by default.

Solo developer Work, Personal Keep billing and projects separate.
