Checking session...
Credentials stay on your machine.
The phone signs into kodx.ai. The companion keeps the Codex login where Codex already runs and sends only the session action you choose.
No open ports or firewall changes.
The companion initiates outbound connections to kodx.ai, so it works behind routers, NAT, and most corporate networks without port forwarding.
