NortonLifeLock for spouse

I do not want to pay for more than one NortonLifeLock. Why do I have to for my spouse to be protected? 

Norton 360 is supposed to be able to be downloaded on more than one computer which is my husbands. Why should I purchase again? That's crazy!

You need to check the exact version of 360 you have. Log into your Norton Account at   https://my.norton.com and click on your user icon at the top right. Then click on My Subscriptions. Look for your current subscription and tell us what version of 360 your have.  ie Standard, Deluxe, Premium.  The Standard version only supports one installation.
