WPA3 is

1. WPA3 (Wi-Fi Protected Access 3): released 2018 by the Wi-Fi Alliance. 2. KEY IMPROVEMENTS over WPA2: • SAE (Simultaneous Authentication of Equals) replaces PSK: resistant to OFFLINE dictionary attacks. • Per-packet forward secrecy. • Wi-Fi Enhanced Open: encrypts traffic even on open (no-password) networks. 3. WPA2's KRACK attack (2017) demonstrated that even WPA2 had practical weaknesses — WPA3 fixed them. 4. WEP (Wired Equivalent Privacy) is completely broken; WPA1 (using TKIP) also vulnerable. Use WPA2-AES or WPA3. _Source: Wi-Fi Alliance WPA3 Specification (2018)._
