Stuck in an endless "duplicate_email" login loop (Case ) — Need backend help!

ChatGPT Support

Environment

  • Surface: Web (Windows/Mac) & Android/iOS mobile browsers
  • Browser or app version: Latest versions of Google Chrome and Brave
  • Affected feature and model, if relevant: Account Authentication / Login Gateway

Bug

  • What happened, and what did you expect?
    My existing ChatGPT account suddenly logged out. When I click “Login” and select “Continue with Google” (using my original email:************), the system bypasses the login screen and forces me into a brand-new user sign-up flow (/about-you). If I try to fill it out, it throws a severe conflict error: This email address is already in use (error_code: duplicate_email). I expected the system to log me directly into my existing profile and chat history.

Reproduction

  • Steps or a minimal example prompt:
  1. Go to ://chatgpt.com.
  2. Select “Continue with Google” (or try typing email manually and clicking “Forgot Password”).
  3. The server skips the login check entirely and routes the browser to a pending signup state (/create-account/password or /about-you).
  4. Attempting to complete the form triggers the duplicate_email exception loop.

Diagnostics

  • Exact error or screenshot: This email address is already in use (error_code: duplicate_email) at the signup validation checkpoint.
  • When it happened (with timezone) and how often: Ongoing loop across multiple independent networks (Wi-Fi and mobile cellular data), multiple different browsers (Chrome, Brave), and separate physical devices (PC and mobile phone). This proves the bug is a server-side account mapping conflict in the backend database.
  • Note: I have an active support ticket open under Case Number: ******** with agent John, but the standard automated troubleshooting steps have failed to break the loop. Seeking engineering assistance to manually clear the pending registration flag on my profile mapping.

I am currently facing this issue today, this morning. I’m from Malaysia by the way.
My ChatGPT suddenly got logged out from both my iOS iPhone as well as my Desktop.
Whenever I wanna log in, somehow it brings me to the sign up page. And when I proceed with the name and age input, it shows me This email is already in use. error_code: duplicate_email.

Please can anyone help me with a solution as I have a monthly subscription in there. I’m so worried that it gets hacked or some sort. OpenAI, can you please do something about it.

no email like this in my mailbox… it’s driving me crazy..

I’m in contact with the “support center” for 2 days now. Most useless thing ever.

they just told me : “after reviewing the email address `…………………@gmail.com`, we were unable to locate a ChatGPT account or subscription associated with that email address in the records checked.”

But I paid!! Like 2 days ago!

Is there a possibility to prove that I paid for THIS email address? I’m paying with Apple store.. can’t find any details related to the account itself to prove anything…

to prove the payment u may have the transaction from your bank account check you apple pay app
from my how many days ago this happened ? is its 7 days if it is more than 7 days than your email is changed and we cant do anything except complaining and since u dont got the email maybe your email is not changed chatgpt migh accidently deleted your account from the database
send email to the support with your screenshot of payment
