Codex Multi-Profile (Windows, Store Codex)

Unofficial helper for people with more than one authorized ChatGPT account. Not for account sharing or bypassing usage limits.

How it works

• Each account = a saved copy of ~\.codex\auth.json in %LOCALAPPDATA%\CodexMultiProfile\accounts\<name>\auth.json.
• The Codex shortcut runs Start-CodexAccounts.ps1 (hidden): it starts the Store Codex inside its package with DevTools on 127.0.0.1:9333, injects switcher-inject.js and stays as the bridge.
• Avatar menu (bottom-left) → Accounts: click = switch (2-3 s: only the codex.exe app-server restarts, the window stays), Add account (Codex restarts on the sign-in screen, the new login is saved under the chosen name), pencil = rename, trash = remove. Ctrl+Alt+A opens the menu, 1-9 pick an account.
• While Codex runs, the live auth.json is copied back into the account in use (Codex rotates refresh tokens; a stale copy would stop working).

CLI (agents)

$cli = "$env:LOCALAPPDATA\CodexMultiProfile\CodexAccounts.ps1"
powershell -NoProfile -ExecutionPolicy Bypass -File $cli list            # -Json for machine output
powershell -NoProfile -ExecutionPolicy Bypass -File $cli status
powershell -NoProfile -ExecutionPolicy Bypass -File $cli save -Name work # save the login in use
powershell -NoProfile -ExecutionPolicy Bypass -File $cli switch -Name work
powershell -NoProfile -ExecutionPolicy Bypass -File $cli rename -Name work -NewName job
powershell -NoProfile -ExecutionPolicy Bypass -File $cli remove -Name old

switch restarts only Codex's app-server (2-3 s, the window stays) and stops a reply in progress; tell the user first.

Rules

• Never print or copy tokens; emails are shown masked (ab***@domain).
• Do not use Codex's own Log out to change accounts: it can invalidate that login's saved copy. Use the menu.
• A watcher (CodexAccountsWatcher.exe, HKCU Run) starts the helper whenever the Store Codex runs without it; from the original icon Codex restarts once to get the menu. status says whether the menu is attached.
• Usage bars come from chatgpt.com/backend-api/wham/usage with each saved account's own token (numbers only reach the page).
• Log: %LOCALAPPDATA%\CodexMultiProfile\codex-accounts.log (masked).
