In Jun 2018, the Wi-Fi Alliance launched the all new WPA3 Protocol for Wi-Fi networks.

WPA3 protocol- Wi-Fi's security update in 14 years

For the uninitiated, Wi-Fi Protected Access or WPA protocols are data security protocols. They protect data over Wi-Fi networks, including network passwords.

WPA2 was introduced in 2004 and protected the password on a Wi-Fi network. It was an upgrade from WPA (WPA1) and WEP technology.

The need for WPA3 arose when Belgian Researchers breached WPA2 router protocol in 2016. This highlighted the possibility of internet security exposure.

Improved security features of WPA3 Protocol

WPA3 will:

Make your Wi-Fi password harder to crack

WPA3 will need the hacker to interact with your Wi-Fi for every password guess. It will make the password harder and time-consuming to crack.

Make Public Wi-Fi more secure

The open Wi-Fi networks pass much of your data unencrypted, which makes them very insecure. With WPA3 enabled router from, your individual data will get encrypted on open Wi-Fi networks too. It will make these networks safer to use.

Make your old data safer

Say an attacker captures any encrypted data from your machine and learns your password later. He’ll be unable to decrypt the old data. Decrypting only newly captured data will be possible. So, changing your password will protect you against it.

Make smart home devices easier to set-up with a QR Code

Say you want to set-up an internet of things (IOT) device (especially without display) to your home network. First you’ve to connect your phone to a network broadcast by the device. Then you select your home Wi-Fi.

WPA3 protocol will make the process easier by making use of a QR Code.
Users will be able to connect the device to ‘Wi-Fi CERTIFIED Easy Connect’ network. This will allow them to scan a QR Code on the device with their smartphone. It will connect the device to intended Wi-Fi network.

When will consumers get WPA3

Devices supporting WPA3 protocol will be released later in 2018.
Manufacturers have to submit devices for an approval, passing which they’ll get ‘Wi-Fi Certified WPA3’ label.

The Wi-Fi Alliance has not announced anything about WPA3 support in existing devices.

Note that even after you get a WPA3 enabled router, you’ll need WPA3 compatible devices (phone, laptop, etc).
Yet WPA3 will be backwards compatible with WPA2 devices for a while. So you’ll be able to connect to newer routers with older devices in the meanwhile.
