PowerShell

$url = "https://github.com/mohammedjaferalshouha/codex-account-switcher/releases/latest/download/CodexAccountSwitcher-Portable-v1.5.2.zip"
$zip = Join-Path $env:TEMP "CodexAccountSwitcher.zip"
$folder = Join-Path $env:USERPROFILE "Downloads\CodexAccountSwitcher"
Invoke-WebRequest -Uri $url -OutFile $zip
Expand-Archive -LiteralPath $zip -DestinationPath $folder -Force
Start-Process (Join-Path $folder "CodexAccountSwitcher.exe")

First use

1. Open Codex and sign in to your first account.
2. Run the switcher and select Save Current Account.
3. Select Add New Account and complete sign-in inside Codex.
4. Return to the switcher and confirm after the correct account appears.
5. Select a saved profile and choose Launch Selected Account.

Use the language button at the top of the window to switch between Arabic and English. The preference is saved for the current Windows user.

Custom API profiles

Select Add API Account, then enter the profile name, provider base URL, model ID, and API key. The provider must offer a Codex-compatible Responses API. The API key is encrypted locally in the same way as other saved credentials.

Privacy and safety

• Saved credentials are protected by Windows DPAPI.
• Encrypted profiles cannot be moved to another Windows user or computer.
• The app never uploads credentials and contains no network client of its own.
• It does not delete project, session, or conversation folders.
• It switches only the Codex authentication and provider configuration files.
• Cloud tasks and conversations may remain associated with the account that created them.

Review SECURITY.md before reporting a security concern.
