While each Extension subscription grants access to one single user, you can, however, use it across multiple computers, but can only be logged in to your extension account on one computer at a time. When your account is logged into on another computer, you will be logged off of the first computer automatically.
Each time you switch devices you will need to re-enter your user name and password. You will need to re-enter your user name and password every 30 days even if you do not switch devices for security purposes.
If you want to use the extension on multiple computers at the same time you will need to purchase another subscription.
To download the extension on another computer, just follow the instructions in the Installing, Uninstalling or reinstalling Extension article.
