Administrative users can make changes that may negatively affect the system or other user accounts. A guest user could potentially fill shared folders with unwanted files. Sharing only users are generally very secure as long as you don't allow excessive access to your account. The potential for mayhem with root user access is nearly unlimited. What are account attributes? - ANSWER Account attributes are the individual pieces of information used to define a user account. Examples include full name, account name, user ID, Universally Unique ID (UUID), group, and home folder. How can you limit a user account from having full access to all applications? - ANSWER Parental controls can be used to further limit a user account.
