Which of the following is a benefit of using a password management program?

Using a password management program provides the significant benefit of securely keeping track of your passwords. These programs are designed to store all your passwords in an encrypted format, which enhances security by ensuring that your login credentials are protected from unauthorized access. This centralized storage allows you to create complex, unique passwords for each of your accounts without the burden of trying to remember all of them.

In contrast to the other options, option B highlights the core functionality of a password manager. While using the same password for all sites could potentially seem convenient, it significantly reduces security by making all your accounts vulnerable if that single password is compromised. Automatically logging you into websites can be a feature of some password managers, but it’s not the primary purpose and depends on the browser's capabilities and settings. Lastly, requiring additional memorization of passwords is contrary to the intent of a password manager, which aims to minimize the cognitive load of remembering numerous passwords by securely storing them instead.
