Which of the following is NOT a technique for access controls?

Access controls are security measures that are put in place to ensure that only authorized individuals can access certain information or resources. Techniques for access control typically involve methods designed to verify identity and protect data integrity.

Tokens, passwords, and unique patient identification are all established techniques used in access control systems. Tokens can serve as a form of authentication, requiring users to present a physical device or code. Passwords are a common security measure, requiring users to provide a secret to gain access. Unique patient identification focuses on ensuring that each patient has a distinct identifier, which is crucial for maintaining accurate and private health records.

On the other hand, Wi-Fi is a technology that enables wireless connectivity to the internet and local networks. While it can be associated with secure access through encryption and security protocols, it does not itself serve as an access control technique. Wi-Fi primarily facilitates connection rather than authentication or access authorization. Therefore, identifying Wi-Fi as a choice that is not a technique for access control aligns with the understanding of what constitutes access control methods in information management.
