Which statement is true regarding the relationship between passwords and user IDs?

The choice that passwords must always differ from user IDs is based on security best practices in information security. This approach minimizes the risk associated with potential unauthorized access. When passwords and user IDs are the same, it creates a vulnerability because if a malicious actor discovers one, they immediately gain access to the user's account. This principle is rooted in the idea that passwords should be complex and unique, adding an additional layer of protection.

While there are various policies around password creation and usage, having distinct passwords that differ from user IDs is a commonly accepted standard. It ensures that even if a user ID is compromised or easily guessed, the associated password remains a separate barrier to access. This further protects sensitive information and helps maintain the integrity of security protocols within systems like NCIC.
