What is one potential risk of using default passwords in a system?

Using default passwords in a system presents a significant risk because these passwords are often widely known or easily accessible and can be readily exploited by malicious users. Default passwords are frequently published in user manuals or online resources, making them predictable targets for attackers. If an attacker gains access to the default credentials, they can compromise the system, potentially leading to unauthorized access, data breaches, or a full system takeover.

In contrast, options that suggest default passwords could enhance system performance, automatically encrypt user data, or ensure consistent user access do not directly address the security vulnerabilities associated with their use. Default passwords do not contribute positively to security and can serve as an entry point for threats, underscoring the importance of changing these passwords upon system deployment.
