forgot psn password, DOB, and email no longer active
I acquired a ps3 from someone and they have their psn account still active on it. It logs in automatically whenever it console is connected to the internet. I talked to the owner to see if I can take over his psn for the dlc on it and he said I can. Now the problem is that he no longer knows his password and his email to that account is no longer active on yahoo. Is their anyway possible for me to get a new password or find out what the old one is. The psn account still has his password and email saved so I can still sign in but I want to be able to access it so i can format the hdd and use it to on my other ps3
Edit: This is weird but i just created an email on yahoo, which is the same email address associated with the psn, apparently they must of deleted the original owners email, idk. However I now need to find or bypass date of birth to even get the email to reset password.
