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

Quick question for @OpenAI_Support while I have your attention: would enrolling in Advanced account security(which disables email/SMS sign-in codes in favor of passkeys) reliably stop my account from ever falling back to phone verification on that dead +44 number? I’d like a permanent fix, but I want to confirm it won’t lock me out given my registered number is dead — and that passkeys fully replace the SMS path. Case 09491223.
