Switch between OpenAI Codex accounts and check remaining five-hour and weekly usage in one Windows dashboard. Codex Manager is a free, open-source companion for the official Codex desktop app. Add your accounts through browser sign-in, compare usage and reset times, and select the account you want to use. Saved sessions stay on your computer.

The screenshot uses fictional demo accounts and sample usage; it contains no real account data.
Watch or download the 20-second walkthrough. This is an illustrated walkthrough with fictional data, not a recording of a real login. The browser sign-in happens on OpenAI's login page.
- Add accounts through browser sign-in without signing out of the existing desktop account.
- Import the current desktop login on first use when one is available.
- Refresh all saved accounts to compare remaining five-hour and weekly usage, reset dates and countdowns, and available credits.
- Show session status and available active-until dates. These dates are not a guaranteed next billing date.
- Switch the official desktop app with a restart, preserving the outgoing account's latest refresh tokens before replacing its login.
- Use a dark dashboard with zoom controls: Ctrl + mouse wheel, Ctrl + +, Ctrl + −, and Ctrl + 0 to reset.
Account sessions can expire or be revoked. Reconnect an account when sign-in is required. Usage and credits depend on what OpenAI returns for that account; unavailable data is not a zero balance.
You need Windows 10 or 11, Windows PowerShell 5.1, and the official OpenAI.Codex Microsoft Store desktop package already installed. Codex Manager uses Windows Presentation Foundation (WPF). Linux and macOS are not supported.
- Download the release ZIP from Releases.
- Right-click the ZIP and choose Extract All. Open the extracted folder.
- Double-click Install.cmd. The installer runs for your Windows user and does not require administrator access.
- Open the Codex Manager shortcut.
- Use Add Account to sign in to another account, then refresh and choose the account you want to switch to.
Finish or pause work in Codex before switching: the desktop app must restart. The manager requests a normal shutdown, then may force-close remaining Codex processes after 12 seconds. See the step-by-step user guide for sign-in, usage interpretation, and troubleshooting.
The release contains unsigned PowerShell scripts. Its launcher uses ExecutionPolicy Bypass for its bundled script process; it does not change your machine's permanent execution policy. Organization policies may still block it. On a managed computer, ask your administrator about approved use; do not disable managed controls.
Saved accounts, profiles, and runtime files live under %LOCALAPPDATA%\CodexManager on your computer. Codex Manager has no service of its own and no telemetry. It contacts OpenAI over HTTPS for authentication and usage, so it is not an offline tool.
Authentication tokens are stored in plaintext files with restricted Windows permissions, not encrypted. The intended access list permits your current Windows user, SYSTEM, and Administrators. Processes running as your user and administrators can still read them. Treat this folder as sensitive: do not upload it, share it, or include it in support reports. Read SECURITY.md before using saved accounts on a shared computer.
Yes. Add each account, refresh the dashboard, and switch the official desktop app to the selected saved account. Add Account uses an isolated browser login flow so the existing desktop account stays signed in while you connect another.
No. It displays the limits returned for each signed-in account and lets you choose an account you are authorized to use. OpenAI's account, plan, and access rules still apply.
Use Refresh to fetch updated usage for saved accounts. A countdown describes the reported reset time; it does not guarantee that limits or credits will stay unchanged until then. Expired sessions may need reconnection.
No. It is a community companion that requires the official Windows desktop package. For the authentication and usage interface used by Codex, see OpenAI's Codex App Server documentation.
No. This release targets Windows 10/11 with Windows PowerShell 5.1 and WPF.
Yes. Three is the number in the demo screenshot, not an application limit. Add each account you are authorized to use; the dashboard reads the saved account list dynamically. Refreshing many accounts may take longer.
Usually you can switch using a valid saved session. OpenAI can expire or revoke sessions, so a saved account may need Reconnect. The manager cannot guarantee permanent sign-in.
Yes, when the service provides reset timestamps. The dashboard shows the reported reset dates in your computer's timezone and a countdown. See the Codex usage limits guide for the difference between reset times, remaining usage, and subscription dates.
This release supports saved ChatGPT account sessions for the official Microsoft Store Codex desktop app. API-key sessions and CLI-only installations are not supported.
Bug reports, documentation improvements, and focused pull requests are welcome. Please read CONTRIBUTING.md, use fictional test accounts and fixtures, and never commit tokens or account data. Release checks should cover installation, login isolation, refresh, switching, and token persistence; authenticated checks require your own authorized test accounts.
