SAE is a password-authenticated key-exchange method based on the Dragonfly protocol. It creates a fresh Pairwise Master Key for every association, so even if an attacker later learns the passphrase, previously captured traffic remains indecipherable. This property is called forward secrecy. SAE does not enable TKIP, does not fall back to WEP, and the four-way handshake still follows SAE to derive session keys.
