Wi-Fi Protected Access (WPA) is a security solution developed as a migration step toward 802.11i. Wi-Fi vendors introduced WPA in late 2002, before 802.11i was ratified. WPA formalized the choice for encryption but left open the choice of authentication. WPA was used as an improvement over the vulnerable WEP but was superseded by WPA2.
