Final answer:
It is best to have each user create their own strong password for separate user accounts on a home computer.
Step-by-step explanation:
When creating separate user accounts on your home computer, it is best to have each user create their own, strong password (option 1). This ensures that each user has a unique and secure password, reducing the risk of unauthorized access to their accounts. Using the same password for all user accounts (option 2) or not setting any passwords (option 3) poses security risks as it allows anyone with access to one account to have access to all. Similarly, using a common, easy-to-guess password for all user accounts (option 4) makes it easier for malicious actors to guess the password and gain unauthorized access.
