WPA3 vs. WPA2: What's the Difference?
Edited by Aimie Carlson || By Janet White || Published on July 20, 2026
WPA3 is the latest Wi-Fi security protocol with enhanced encryption and security features, whereas WPA2 is the previous standard with less robust security measures.
Key Differences
WPA3, introduced in 2018, incorporates improved cryptographic strength compared to its predecessor, WPA2, which has been the standard since 2004. WPA2 uses the AES encryption standard, while WPA3 introduces more advanced encryption protocols.
WPA3 enhances protection against offline dictionary attacks, a vulnerability in WPA2, by implementing Simultaneous Authentication of Equals (SAE). WPA2, while secure, is susceptible to such attacks, especially on networks with weak passwords.
WPA3 offers forward secrecy, meaning that if a session key is compromised, past communications remain secure. In contrast, WPA2 does not provide this level of security, potentially exposing older data if a key is compromised.
For public Wi-Fi networks, WPA3 provides individualized data encryption (OWE) to secure connections on open networks, a feature not available in WPA2. WPA2's security on public networks is less robust, relying on the same encryption key for all users.
WPA3 is designed to be more secure against brute-force attacks compared to WPA2. WPA2's security can be compromised with sufficient time and computing power, especially when using weak passwords.
