Locked out of Codex because of an old phone number?
OpenAI Developer Community
July 3, 2026
@OpenAI_Support Having same issue Case Number: 10890586 This started after I upgraded my subscription from ChatGPT Plus to Pro. Before the upgrade, I was able to use my account normally, but after switching to Pro, Codex started requiring verification through an old phone number that I no longer have access to.
ChatGPT web login still works, and I’ve already added passkey/passphrase-based sign-in and replaced the old password-based login flow with the current secure authentication methods. However, Codex still forces legacy phone verification instead of using my current passkeys/MFA.
