Yes, it is possible to add more devices to the existing Norton 360 subscription. This is done through the Norton Management interface, by buying additional product keys. Here is how to do it:
- Log on to Norton Management (click to open it in a new window),
- click the My Account tab,
- on the My Account page,
- click Product Details,
- click on the Norton product for which you need additional product keys,
- in the Manage My Installs section, click Buy A Key,
- simply follow the on-screen instructions.
If you have 5 or more computers, you may consider Norton 360 for up to 5 or 10 users.
As Norton 360 has been replaced with Norton Security, multi-license options are available through this service now. Here is the multi-license product page at Norton.com.
