FAQ

Questions.

Do I need a computer or the Codex CLI?

No. Codex setup is done entirely on your phone.

The code expired. Now what?

Codes are valid for 15 minutes. When one expires, press B for a new code.

How long does the sign-in last?

The device renews it automatically, about every 10 days. If it lapses the screen says Codex login expired: hold B about 7 seconds and sign in again. Your Wi-Fi is kept.

Does it see my ChatGPT password?

No. You sign in on OpenAI's own page on your phone. The device stores only its own sign-in, on the device.

Stop guessing.
