Hot-swap Codex accounts

Running multiple Codex accounts to maximize tokens is common. DevAgent lets you hot-swap the active account in one click, with no re-login and no config editing. The same flow works for Claude Code accounts.

Add accounts

1. Log into each Codex account from a terminal at least once, so the auth sits under ~/.codex.
2. Open Settings → Agents → Codex Accounts.
3. DevAgent lists all detected accounts with their usage and current limit.
4. Give each one a friendly label — "personal", "work", etc.

Swap accounts

Click the Codex chip in the status bar to open the account switcher. Pick an account; any new Codex session launched after that uses it. Sessions already running keep their original account until restarted.

System default

The System default row is your current host Codex login under ~/.codex. Managed accounts (added in DevAgent) do not rewrite that login; they run in isolated homes. Select System default when you want launches to match a terminal codex outside DevAgent.

When config edits seem ignored

For managed Codex accounts, DevAgent mirrors settings from your real ~/.codex/config.toml into the active runtime home. If that source file is missing, empty (e.g. cloud-sync still downloading), or unreadable, Accounts shows a warning: Codex keeps the last successfully synced settings until the source is healthy again. Fix the file at the path named in the banner, then relaunch or reselect the account.

Rules & gotchas

• Swapping is instant — DevAgent rewrites the active credential pointer, it does not re-authenticate.
• Existing Codex processes keep their current account until restart.
• Usage readouts in the status bar follow the currently-active account.
• The restart chip preserves the active account at the time of restart.

Claude Code accounts

The Claude account switcher works identically — different data directory (~/.claude), same UX.
