WPA2 vs WPA3

WPA3 improves Wi-Fi security over WPA2 with stronger handshakes and protections.

Updated: 2026-03-06

Definition

WPA2 uses PSK/802.1X with AES; WPA3 improves protection against offline guessing and adds better encryption options.

Enterprises often use WPA2-Enterprise/WPA3-Enterprise with 802.1X and RADIUS.

Key points

WPA3 improves resistance to password guessing
Enterprise mode uses 802.1X + RADIUS
Avoid legacy/weak modes

Common mistakes

Using weak PSKs and never rotating them.
Mixing legacy compatibility settings that weaken security.
