What protection does WPA3 wireless encryption provide over WPA2 for securing wireless networks?

WPA3 introduces improvements over WPA2, most notably replacing the PSK (Pre-Shared Key) handshake with the Simultaneous Authentication of Equals (SAE) handshake.

The SAE handshake is resistant to key reinstallation attacks (KRACK) that affected WPA2.

WPA3 also improves security in open networks but does not force enterprise-only mode or universally block all legacy protocols, and 128-bit key size alone isn’t unique to WPA3.
