What does the dual control policy require before accessing a password?

The dual control policy is designed to enhance security by requiring a form of oversight before sensitive actions, such as accessing passwords, can be executed. In this case, requiring managerial approval aligns perfectly with the principles of dual control, where one person's actions are subject to verification by another. This ensures that no single individual has complete control over critical functions or access to sensitive information, thereby significantly lowering the risk of unauthorized access or misuse.

In environments where privileged access is tightly controlled, having a manager provide approval adds an important layer of accountability and oversight. This not only enhances security but also ensures that organizational policies governing access are adhered to, as managers are typically responsible for enforcing compliance with such policies.

The other options, while they contribute to security in different ways, do not specifically align with the concept of dual control. Multiple accounts approving access emphasizes collaborative permission but is less practical and not necessarily the established method in every organization. Biometric scans can provide strong verification for access but do not inherently require an authoritative review by a manager. Similarly, the use of a security token focuses on two-factor authentication rather than creating a supervisory layer for access decisions. Thus, managerial approval is the most fitting requirement under the dual control policy.
