(adsbygoogle = window.adsbygoogle || []).push({}); Alright, so I have this sub-account, but when I try to log in it says

"You must ask the holder of the associated master account to help you sign in.

＜Note to parent or guardian＞
For the sub account holder to sign in, you must accept the Terms of Service / User Agreement and Privacy Policy again using your master account."

The only problem is that I have no idea what the associated master account is. I was wondering if there was a way to retrieve the email and password of the associated master account so that I can finally sign in?

Yes, the problem is that my playstation's hard drive became corrupted a while ago. I had to do a full restore and I lost all of the other accounts. This is the only account that is important to me, I just don't know the master account that is associated with it. Is there anyway to find out what it is?

No, all of the accounts are mine. I must have obviously made a master account for this sub-account. I just do not remember what the email to that account is.
My only question is that if I know the email and password to the sub account, is there any way to recover the Main account's email?
