WPA3 vs. WPA2: Know the Difference
By Shumaila Saeed || Published on February 6, 2024
WPA3 is an advanced Wi-Fi security protocol with enhanced encryption and security features, while WPA2 is its predecessor with less robust security measures.
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.

In WPA3, the introduction of Wi-Fi Enhanced Open provides more secure public Wi-Fi connections. WPA2 lacks this feature, making public Wi-Fi networks more susceptible to eavesdropping and other attacks.
