What is the required action for WPA/WPA2 (PSK) authentication on SSIDs?

WPA/WPA2 (PSK) authentication is designed for securing wireless networks through a pre-shared key, or passphrase. When it comes to SSIDs (Service Set Identifiers), the essential action required for establishing a secure connection involves specifying this passphrase. The passphrase must meet certain length and complexity requirements to ensure adequate security. Once the correct passphrase is entered by a user on their device, they gain access to the network, provided all other security measures are in place.

In contrast, a pin code is typically associated with WPS (Wi-Fi Protected Setup) and not the regular WPA/WPA2 authentication process. Connecting to a RADIUS server pertains more to WPA/WPA2 Enterprise configurations, which use a different authentication method that involves server-side verification. Creating a guest account is useful for managing temporary access to the network but does not directly relate to the authentication requirements for WPA/WPA2 (PSK) on SSIDs. Therefore, specifying the passphrase is the key requirement for ensuring that only authorized users can connect to the secured wireless network.
