Codex ChatGPT login flow

[D4Vinci-CDM]

What issue are you seeing?

I am paying for ChatGPT Plus and cannot access Codex through the advertised ChatGPT login flow.

This is not an API key issue. Codex CLI is installed correctly. Both codex login and codex login --device-auth redirect me to auth.openai.com/add-phone.

This appears to be a known/auth-related Codex issue:

• Phone number verification doesn't work #20161
• ChatGPT asking phone number verify but didn't send any code yet #20320
• Codex asks for a number despite already having 2fa setup #20813
• PLEASE REMOVE THE PHONE NUMBER REQUIRMENT OR THE LIMIT #20884

Please either:

1. remove the phone verification gate from my account for Codex ChatGPT-login;
   !!! confirm in writing that Codex ChatGPT-login now requires phone verification for paid Plus users !!!!

What steps can reproduce the bug?

1. I have an active ChatGPT Plus subscription.

2. I installed the official Codex CLI on Windows.

3. I checked that Codex CLI is installed correctly by running:

   Get-Command codex

   PowerShell detects codex.exe, so the CLI is installed and available in PATH.

4. I am not trying to use an API key. I am trying to sign in through the official ChatGPT login flow.

5. I run:

   codex login

6. Codex starts a local login server on localhost and opens the official OpenAI authentication page in the browser.

7. Instead of completing the ChatGPT/Codex login, the OpenAI authentication flow redirects me to:

   auth.openai.com/add-phone

8. The page says that a phone number is required to continue.

9. I also tried the official device authorization method:

   codex login --device-auth

10. Codex gives me a device code and asks me to open:

https://auth.openai.com/codex/device

11. After entering the device code and signing in to my ChatGPT Plus account, the same problem happens again: OpenAI redirects me to the phone verification page.

12. This confirms that the problem is not with my Windows installation, not with PowerShell, and not with the Codex CLI itself.

13. The issue happens inside OpenAI’s own authentication system, during the official ChatGPT/Codex login flow.

14. This is not an API key flow, so the API key phone verification requirement should not apply here.

15. As a paying ChatGPT Plus user, I expected to access Codex through the advertised ChatGPT subscription login path.

16. However, I am blocked from using Codex unless I provide a phone number.

What is the expected behavior?

I encountered a completely opposite problem. My account was initially registered with a phone number. After logging in with the phone number, OpenAI asks me to bind/verify an email address. I can receive and enter the verification code, but then the page shows an error. If I click the retry button, it appears to succeed, but no actual authentication is generated, it does not redirect back to Codex, and when I try to log in to Codex again, I get stuck in the same loop.

Errors I observed include:

• Server error 500
• Route Error 400 Invalid content type
• missing_route_prerequisite_data

I have an active ChatGPT Pro subscription, and ChatGPT web works normally with the same account, but Codex CLI / Platform authentication cannot complete.

Environment:

• Windows + PowerShell
• Codex CLI 0.135.0
• Tried both codex login and codex login --device-auth

I also tried reinstalling Codex CLI, clearing local auth data, using different browsers / incognito mode, but the authentication loop still happens.

Yeah, this issue also I've heard from some of my friends, but the issue is they cannot stop the people who are abusing the accounts, and they are troubling the entire world with these nonsense things.
The problem is with Codex only. I don't know what they are doing. What is the reason for them to do it?
The people who are able to bypass Codex and use it are able to use it. Genuine customers are having issues.

Once, the issue I am getting is that whenever I try to log in, I use multiple accounts. For some accounts, I have no issues, but for some accounts it is repeatedly asking me to verify with the OTP.

I have a phone number that can be verified by SMS.
It can help you activate your account.

This is really stupid. I followed OpenAI's official path completely. I didn’t use any tools from GitHub that are reverse proxies for the official website, and still, I can’t use it. Those who use abuse tools can enjoy it, while those who use the official tools can’t access it at all.

是的，我也从一些朋友那里听说过这个问题，但问题在于他们无法阻止那些滥用账号的人，这些人用这些无稽之谈扰乱了全世界。 问题似乎只出现在 Codex 上。我不知道他们到底在干什么。他们这么做的目的是什么？ 那些能够绕过 Codex 并正常使用的人可以继续使用，而真正的用户却遇到了问题。

我遇到的问题是，每次尝试登录时，我都会使用多个账户。有些账户登录没有问题，但有些账户却会反复要求我使用一次性密码 (OTP) 进行验证。

I don't know why they do this. When I replied to inquiries about this issue in the group and on social media, I was even ridiculed by those who used special means to verify their identity.

ChatGPT just pulled out my "primary phone number" out of its butt (maybe old phone number that used to be listed on my Google acc - I login via Google). Codex stopped working today unless I verify that phone number it pulled out of its butt. No visible way to change.
