Duplicate Codex accounts warning: what it means

Seeing “Duplicate Accounts Detected” is not an error. CodexUse found two or more profiles tied to the same OpenAI identity and is telling you up front that they share one rate limit, so switching between them won't buy you more headroom. Nothing is blocked.

Why the warning appears

• CodexUse derives a rate-limit identity from the OpenAI login it receives. When two profiles resolve to the same identity, it flags them.
• Only Codex CLI profiles are checked for duplicates.
• The rate-limit radar treats those profiles as one pool, so switching between them adds no extra quota.

What to do about it

• If the profiles really are the same OpenAI identity, keep one and delete the duplicate.
• If you keep several on purpose, that's fine, just remember the limit is shared. The switch buys separation, not extra headroom.
• Give each profile a clear name (for example, “Workspace seat A” and “Workspace seat B”) so you can tell which is active in the tray.

How to dismiss the notice

• Click the close icon on the warning. CodexUse remembers the dismissal locally.
• It returns only when the set of duplicates changes, so you'll still catch any new overlap.

Other signals that rely on account IDs

• The rate-limit radar shows usage per rate-limit identity, so duplicates share one bar.
• Auto-roll (Pro) can rotate within the duplicate pool, but it can't escape the shared limit.
• Codex App window control and profile switching keep working. The warning never blocks an action.
