To keep folks from buying one download and illegally selling copies of the download to others the TT program now requires all 5 downloads to be registered using the same user's account.
If you are using the download for multiple family members (like your kids who use their own computers) you should have no qualms about giving them your userID and password to your account. This only registers the download to each computer ... at no time will they be able to see the returns on your computer and you will not see their returns on their computer.
