WPA3 (Wi-Fi Protected Access 3) is the latest security protocol for Wi-Fi networks. It was introduced in 2018 and offers several enhancements over WPA2, including stronger encryption, improved authentication, and easier network configuration.
WPA3 uses a new encryption algorithm called Simultaneous Authentication of Equals (SAE), also known as Dragonfly, which is designed to make it harder for attackers to crack Wi-Fi passwords through brute-force attacks. It also introduces individualized data encryption, meaning that each device on the network has its own unique encryption key, making it more difficult for attackers to intercept and decrypt data.
Another key feature of WPA3 is Easy Connect, a new method for securely connecting smart home devices to Wi-Fi networks without the need for a password. Instead, users can simply scan a QR code or use Near Field Communication (NFC) to connect their devices securely using public key cryptography.
Overall, WPA3 represents a significant improvement in Wi-Fi security and is recommended for anyone setting up a new Wi-Fi network or upgrading an existing one.
