WPA2-Personal (PSK) uses which type of credential?

• A. A shared password for all clients
• B. Per-user credentials via 802.1X
• C. Certificate-based authentication
• D. Biometric authentication

Answer: (A)

WPA2-Personal uses a pre-shared key: a single secret password that is configured on the access point and on every client device. This means everyone who connects uses the same credential, which keeps setup simple for small networks like homes or small offices. It lacks per-user authentication, so you don’t get individual user logins or centralized access control—anyone who has the password can join.

This is in contrast to WPA2-Enterprise, which uses per-user credentials through 802.1X with a RADIUS server, or certificate-based authentication, where certificates are used to verify each device or user. Biometric authentication isn’t a method used in WPA2 authentication at all.
