1) Log in to your RoboForm Online Account here.
2) Select the "Licenses" tab at the top of the page. Click the “Upgrade to Family plan" link.
The upgrade price is calculated based on the number of days left in your current individual license. In order to upgrade, you have to renew for a full year. Your new family plan expiration date, however, will reflect the pro-rated remainder of your current individual subscription.
