Short answer: the ChatGPT desktop app on Windows (formerly the Codex app, from the Microsoft Store) keeps one login, and as a Store app it can't simply be copied. The free routes all cost you something: OpenAI's account switcher and browser profiles only work on the web, and a second Windows user means switching your whole desktop. Sessions Pro for Codex runs the ChatGPT app once per account, each in its own window, all signed in at once.
Free 1-hour preview once you've signed in to a profile. For macOS 14 or later, or Windows 10 or 11, with the ChatGPT desktop app.
Why the ChatGPT app on Windows holds one account
The ChatGPT desktop app comes from the Microsoft Store (its package is still OpenAI.Codex). It keeps its login in %APPDATA%\Codex\web\Codex and its Codex data, login and threads in %USERPROFILE%\.codex. One set of folders, one account: signing in to another replaces the first. And because Store apps live in a protected folder, you can't make a second copy of the app by hand the way you can on a Mac.
The free options, and what they cost you
- The web switcher. OpenAI's account switcher keeps two accounts on chatgpt.com, one at a time. It only works on the web version, which doesn't help if you build real projects in the desktop app.
- Browser profiles. An Edge or Chrome profile per account keeps each signed in to chatgpt.com. Still the website: no desktop app, no Codex working in folders on your PC.
- A second Windows user. Each Windows user gets their own ChatGPT app data and
.codex. Fine for two people; for one person it means switching your whole desktop every time.
For the Codex CLI alone, a CODEX_HOME per account is free: two Codex accounts on Windows. It doesn't touch the desktop app.
Each account, its own window.
Sessions Pro for Codex for Windows runs the ChatGPT app you already have once per account, each in its own window titled with its profile name (for example "ChatGPT — Work"), with its own taskbar button, letter and color. All of them stay signed in and open at the same time; switch from the taskbar, the tray or Alt-Tab.
Each keeps its own login, chats, Codex threads, projects and pins, and "Codex CLI in Terminal" opens the CLI on the same account. Sign-in opens in a private browser window, so each profile asks which account to use, and you can start from your current ChatGPT so nothing is lost. Try it free for an hour once a profile is signed in; then it's $24.99 once for two computers, Mac or PC, with a 14-day refund.

FAQ
Can I use two ChatGPT accounts in the Windows desktop app?
Not in one copy: the app holds one account, and OpenAI's account switcher only works on the web version. Sessions Pro for Codex runs each account in its own ChatGPT window, all signed in at once.
What do I need?
Windows 10 or 11 (x64 or Arm) with the ChatGPT desktop app from the Microsoft Store. One Sessions Pro for Codex license covers 2 computers, Mac or PC.
What's different on Windows?
A few things: codex:// links and the ChatGPT tile in the Start menu open your normal ChatGPT, not a profile, and the first time you use Codex in a profile, ChatGPT asks to finish its Windows setup, one click per profile.
Is it allowed to use multiple ChatGPT accounts?
Sessions Pro for Codex runs the official ChatGPT app with accounts you already have, such as a work account and a personal one. It doesn't change how ChatGPT or Codex work, and OpenAI's terms apply to each account. Use it for accounts you're allowed to have, not to get around usage limits.
Sessions Pro for Codex is made by LEX GLOBAL IT S.R.L. and is not affiliated with, endorsed by or sponsored by OpenAI. It runs the official ChatGPT app with accounts you already have, and OpenAI's terms apply to each account. ChatGPT and Codex are trademarks of OpenAI.
