Codex client auth forces WhatsApp code to a dead number — but ChatGPT/Codex web log in fine (Case 09491223)

I have the same request as well — a permanent fix for this issue. @OpenAI_Support
Either Codex should completely stop using the original registered phone number for login verification and instead use the SMS method configured under MFA, or OpenAI should provide a way for users to update the original registered phone number.
It is very difficult for users to keep using your service while constantly worrying that they may be locked out of their account one day.
