What is the name of the "authentication" method that lets anybody with the password access a WiFi network?

1. Pre-Shared Key (PSK)

2. Password Authentication (PA)

3. Extensible Authentication Protocol (EAP)

4. Service set identifier (SSID)

The correct answer is: Pre-Shared Key (PSK)

The correct answer is Pre-Shared Key (PSK). This authentication method involves the use of a shared password that is known to all users who want to access the wireless network. When a user attempts to connect to a WiFi network that employs PSK, they must input the correct password; if they do, they gain access to the network. This method is straightforward and often used in home and small business settings due to its simplicity. While PSK allows for easy access for those who know the password, it also has some security implications. If the password is shared too widely or if it is not strong enough, unauthorized individuals may also gain access. Therefore, while effective for convenience, it's important to manage the sharing of the PSK carefully. In contrast to PSK, other methods listed involve different levels of security and complexity. For instance, EAP is a framework for various authentication methods often used in enterprise environments, which offers more secure options than mere password entry. Password Authentication (PA) sounds similar, yet it is not a commonly recognized term in networking. Lastly, SSID refers to the name of the wireless network itself and does not pertain to the authentication methods. Understanding the implications and functionalities of these terms is crucial for effective network
