Change login method from google authentication to login and password

I am using the webiste chat openai com, with a premium pass. I authenticated using my Google account. How can I switch the authentication method to login and and password?
(I don’t want to create a new account, as I would loose my premium pass).



I’ve got the same issue. Have you found the solution ?

But this is not going to work, right? They will not see ChatGPT 4.
