What is the difference between WPA2 and WPA3 for wireless security?

Wi-Fi Protected Access 2, or WPA2, uses AES encryption with either a pre-shared key for personal networks or 802.1X authentication for enterprise networks. WPA3 improves security in several ways: it replaces the pre-shared key exchange with Simultaneous Authentication of Equals, or SAE, which resists offline dictionary attacks; it provides forward secrecy so captured traffic cannot be decrypted later even if the password is compromised; it offers stronger encryption with 192-bit security for enterprise mode; and it includes Wi-Fi Enhanced Open for encrypted connections on public networks
