Amongst the enhancements, WPA3-Personal includes a more robust password-based authentication system that reduces the chances of a hacker guessing your password, individualized data encryption to protect against Wi-Fi eavesdropping, and the ability to protect data traffic even if a password is compromised after the data was transmitted.
On the enterprise side, WPA3 also offers an optional mode using 192-bit minimum-strength security protocols, as well as cryptographic tools to better protect sensitive data.
WPA3 also includes new quick-setup options for smart home devices through Easy Connect, a smartphone-based feature for users to set up wireless devices that lack displays.
Support for WPA3 must be built into devices for the protocol to be enabled, so it won't start coming into general use for a while yet. The good news is that WPA3 will retain interoperability with WPA2 devices, so there won't be a need to update every device on the same network.
The Wi-Fi Alliance expects WPA3 certification to increase over the next year, and as adoption grows, the protocol should eventually become a market requirement for all Wi-Fi certified devices.
