An account profile is created for the purpose of data collection and customer identification (during a support call). An account profile does NOT correspond to an account login. For a specific hosting account, there is only one account login (username and password), but there could be multiple account profiles. If you call customer support, and you are not the account owner, your information should be set up in your account profile.
An account profile describes a person with access to your account, such as the site owner, administrator or Webmaster. We collect your contact information, information about your technical environment, experience, and interests. We then use this information to keep you informed about your account, changes to our systems, and any new or special offers that might be of interest to you.
If multiple people access your account, you can create a profile for each of them based on their role and interests. (Just remember that they still have just one username and password)
