Right now, Im running a trial version of Smart security, however I am trying to figure out the licensing concept. It is my assumption that they use a "USERNAME" and "PASSWORD" method of authenticating the subscriptions instead of a license key? Am I correct? and the user name and password are given at the time of installing the software? Is this password changeable? or are we stuck with it forever? What if I buy a 3 user license and due to any reason want to change the password in the middle of the subscription period, will I have to change the passwords on all 3 computers? Or will they continue to download updates? Sorry for the long question, I am just a little curious. Thanks alot for all the help.
