WPA3 Personal does indeed use Simultaneous Authentication of Equals (SAE) as a replacement for the Pre-shared Key (PSK) in WPA2. SAE enhances security by providing forward secrecy and protection against offline dictionary attacks, where an attacker attempts to guess the network password using a list of potential passwords. Unlike earlier versions, WPA3's SAE mechanism requires interaction with the live network for each password attempt, thus mitigating the risk of offline attacks.
