Hi, I'm Sudipto. Welcome to JustAnswer. I'm reviewing your question now, and will post back with your reply ASAP
Can you tell me the email ?
> I reached someone who set up a separate email account with me and sent me 6 digit codes that dont work.
Obviously you provide insufficient or incorrect information to Google. Was your Gmail associated with your cell phone and/or 2nd email address for recovery Does any device or computer of you still have access to the Gmail account?
BTW, do not repeatedly try different passwords a day and this will cause your account disabled due to suspicious attach behavior.
Do you still need our help here?
