I would think to secure a PSN just edit all of the account info as soon as possible Ex: birthday, email, name and password. I lost a old PSN of mine and I mean real old and I gave them some basic info but without the birthday and something else but they would not give me the account details.
I'm also looking for a new main and something that is a nice OG so if anyone has anything PM me

Btw: I used to have an Xbox but I no longer have one, but hope to get a new one soon and start posting more even though I dont have one
