The Wi-Fi Alliance, which oversees Wi-Fi standard adoption, is now certifying products that support WPA3, marking a major security advance over the WPA2 protocol that has been in use since 2004.

The new protocol makes it more difficult for hackers to crack passwords through repeated guesses, because attackers will only be able to make a single guess against offline data. Subsequently, they will have to interact with the live Wi-Fi device for every guess.

In addition, a new privacy feature called forward secrecy will restrict the data hackers can see even with the passcode. Forward secrecy prevents older data from being compromised by a later attack. However, WPA3 protections will take many years to roll out as users purchase routers and other equipment that support the protocol.

The Wi-Fi Alliance expects WPA3 rollout to increase over the next year, but the protocol is not currently mandatory in new products.

The next generation of Wi-Fi itself, 802.11ax, is also rolling out, and is projected to reach mass adoption late next year.
