I can sign in to ChatGPT Web normally using Google SSO.
My account was created using Google and has never had a phone number associated with it.
However, when I sign in to the ChatGPT Desktop / Codex client, after successfully completing Google
authentication, I am redirected to a “Phone number required” page.
The verification page does not support the China (+86) country code, so I cannot complete the
authentication flow.
This appears to be a Codex/Desktop OAuth phone-verification issue rather than a normal request to add
or change a phone number.
ChatGPT Web continues to work normally with the same account.
Please review my account and reset/remove the unexpected phone-verification requirement from the
Codex/Desktop authentication flow.
Thanks for sharing the details @panwang.0611
Since you’re able to sign in on ChatGPT Web but are encountering the phone verification prompt specifically with the Desktop/Codex client, this will need a closer look at your account and authentication flow.
Please submit a support ticket through the OpenAI Help Center so our Support team can review this further.

I am experiencing essentially the same Desktop authentication behavior in Canada on Windows 11. ChatGPT Web works normally, but ChatGPT Desktop redirects me to “Phone number required.” Unlike the OP, I do not have a mobile number at all, so there is no way for me to complete the flow.
I have had two OpenAI Support cases open over nearly two weeks and have already provided multiple screen recordings, HAR and Chrome NetLog captures, but support keeps sending me back through generic phone-verification troubleshooting instead of reviewing the Desktop authentication flow.

@OpenAI_Support — you mentioned above that this Web-works/Desktop-phone-verification pattern requires “a closer look at your account and authentication flow.” Could my case please receive that same review?
