Just a QN about identity management

How does codex-profiles keep each profile’s login and conversation history separate? Can I run two ChatGPT windows with different accounts at the same time?

Yes — on macOS, you can run two named ChatGPT windows side by side and sign into a different account in each.

Each profile selects its own local directories. For example, work uses:

• ~/.codex-work for Codex authentication and local conversation/session state.
• ~/.codex-work/electron-user-data/ for the named ChatGPT window’s Electron data.

A personal profile uses the corresponding ~/.codex-personal directories. The selected window state covers Chat, Work, and Codex. The tool selects those directories; it never reads or copies authentication tokens or ChatGPT cookies.

To start both:

codex-profile init personal
codex-profile init work
codex-profile app personal
codex-profile app work

Sign into the desired ChatGPT account in each window when prompted. Reopening the same profile reuses its process and local data. If you also use the Codex CLI, authenticate each profile separately with codex-profile login personal and codex-profile login work; CLI and Desktop sign-in are separate, and the tool does not verify that they use the same account.

One distinction about history: this separates local state. It does not split server-side conversation history into separate accounts if you sign into the same account in both windows. It is also not an OS security boundary—keychains and external CLI credentials remain shared by the OS user.
