WPA3 is an advanced Wi-Fi security protocol with enhanced encryption and security features, while WPA2 is its predecessor with less robust security measures.
WPA3 vs. WPA2

Key Differences

WPA3, introduced in 2018, is the latest Wi-Fi security standard, providing stronger encryption through individualized data encryption. WPA2, established in 2004, uses a less secure encryption method and is more vulnerable to attacks like KRACK.

WPA3 employs Simultaneous Authentication of Equals (SAE), a more secure method for initial key exchange, reducing the risks of offline dictionary attacks. WPA2, however, relies on the Pre-Shared Key (PSK) method, which is susceptible to brute force attacks.

WPA3 offers forward secrecy, ensuring that past communication remains secure even if a current key is compromised. WPA2 does not provide this, making past communications vulnerable if the key is cracked.
