NIS 2012 on 2 PC's. How do I create a 2nd Identity Safe Profile?

  I have Norton Internet Security Suite 2012 on both of my Computers at home and my brother uses my second computer so I'd like for him to be able to set up his own Identity Safe Profile to save all of his passwords.  It'll just make everything so much easier for him.  How do I go about setting it up for him on my second computer?  Thanks in advance.
