Hacking an account

Hello good sirs. I currently have access to an account that I know the user and password to. I am planning on stealing the account by changing the password, I want to know if anyone knows how I could make the account unrecoverable, or the least possible. I am pretty sure the current owner hacked it off someone else but still.


-Any help greatly appreciated :)

In order to make it partially unrecoverable you must have access to the email attached to the account also.
However, the owner can provide CC statements and previous passwords/security question-answers and possibly still recover it.

Ok, thanks. I'll probably just change the pw and hope for the best then.

Solved. Closed.
