## Signing in to Claude or Codex

- Open **Settings › General › Models** and click **Login** next to the provider. The browser opens; finish the sign-in there and come back.
- If the chat says your session expired, sign in again the same way.
- A sign-in that hangs can be cancelled and started again.
