**WPA3** is a secure Wi-Fi protocol and is growing in usage as more WPA3 compatible devices are released. These are the key differences between WPA2 and WPA3: - WPA3 addresses the authentication handshake vulnerability to KRACK attacks, which is present in WPA2. - WPA3 uses *Simultaneous Authentication of Equals* (SAE), a password-authenticated, cipher-key-sharing agreement. This prevents attackers from downloading data from wireless network connections to their systems to attempt to decode it. - WPA3 has increased encryption to make passwords more secure by using *128-bit encryption*, with **WPA3-Enterprise** mode offering optional *192-bit encryption*.
