Zara has introduced wireless authentication to her network through the distribution of a passphrase to every member of her organization. What category of authentication method has she employed?

Zara has utilized the pre-shared key (PSK) authentication method, which implies that in the event of a staff member's departure necessitating a change in the key, every device must update its passphrase. For more extensive deployments, enterprise authentication can link to an authentication and authorization service, allowing each user to authenticate themselves. This also enables network administrators to identify individual devices based on their authenticated users. Open networks do not require authentication, although a captive portal can be used to demand that network users provide information before accessing the Internet.
