WPA3 is a new and stronger security protocol for modern wireless networks (WiFi). The term stands for WiFi Protected Access.
Thanks to modern encryption methods (Simultanious Authentication of Equeals - SAE), increased security is ensured. This encryption prevents passwords for your WiFi network from being tried through with the help of word lists.
Other security functions are also mandatory, such as PMF (Protected Management Frames). This creates a more secure exchange of data during the logon phase between the client and the WiFi network (controller).
