How do I transfer a NIS2011 licence from my Norton Account to someone elses?

I regularly rebuild and fix laptop / PCs and often advise NIS for my client’s overall protection.  However, to save time I use my Norton Account to register the NIS licence as I don’t know if the client has a Norton account or not (and if they did, they would not tell me the username or password).

 

My question is, if I were to help setup and Norton account for my clients, how do I then transfer a NIS licence (1x household for 3x PCs for example) from my Norton account to my clients, newly created?
