Wi-Fi devices have been using the same security protocol for over a decade. But today, that’ll begin to change: the Wi-Fi Alliance, which oversees adoption of the Wi-Fi standard, is beginning to certify products that support WPA3, the successor to the WPA2 security protocol that’s been in use since 2004.

The new protocol provides a number of additional protections for devices connected over Wi-Fi. One big improvement makes it harder for hackers to crack your password by guessing it over and over again, and another limits what data hackers can see even once they’ve uncovered the passcode. Nothing will change as far as users see it; you’ll still just type in your password and connect to the network.
