Unable to Verify Phone Number for Codex Login (WhatsApp Required, SMS Not Received)

[sudarshandhokale]

What version of the Codex App are you using (From “About Codex” dialog)?

Version 26.527.60818 (3437)

What subscription do you have?

ChatGPT Plus

What platform is your computer?

Darwin 25.5.0 arm64 arm

What issue are you seeing?

I am unable to log into Codex because the phone verification process does not work.

During login, Codex asks me to enter a verification code that was supposedly sent to my German phone number via WhatsApp. However, this phone number is not registered with WhatsApp, and I do not receive any SMS verification code either.

There is no option to switch from WhatsApp verification to SMS verification, use another verification method, or change the phone number associated with verification.

As a result, I am completely blocked from accessing Codex despite having an active ChatGPT Plus subscription and being able to log into ChatGPT normally.

What steps can reproduce the bug?

Steps to reproduce:

1. Open Codex and start the login process.
2. Sign in with my OpenAI account.
3. Complete account authentication.
4. Reach the phone verification screen.
5. Codex requests a verification code sent via WhatsApp.
6. No WhatsApp message or SMS is received.
7. Login cannot be completed.

What is the expected behavior?

Expected behavior:

1. Receive a verification code via SMS.
2. Have an option to use an alternative verification method.
3. Be able to complete login successfully.

Actual behavior:

1. No verification code is received.
2. No alternative verification method is available.
3. Login process is blocked.

Additional information

Additional Information

• I am located in Germany and using a German mobile phone number (+49).
• The phone number is valid and active.
• The verification screen specifically states that a code was sent via WhatsApp.
• This phone number is not registered with WhatsApp, so I cannot receive WhatsApp messages on it.
• No SMS verification code is received as an alternative.
• I cannot find any option to switch from WhatsApp verification to SMS verification.
• I cannot find any option to use a different phone number or another verification method.
• My ChatGPT account is working normally and I can access ChatGPT without issues.
• I have an active ChatGPT Plus subscription.
• I have retried the verification process multiple times and the issue persists.
• I have tried different browsers/networks and the result is the same.
• This issue prevents me from using Codex entirely.

If this is expected behavior, please advise how users without WhatsApp on their phone number can complete the verification process and access Codex.
