# What are WPA2 and WPA3?

WPA2 and WPA3 (Wi-Fi Protected Access, versions 2 and 3) are the security standards that encrypt Wi-Fi traffic and control who may join a wireless network. WPA3 is newer and better protects against password guessing. For an office, use WPA2 or WPA3 with a strong password, or better, the enterprise mode where each person signs in with their own account, so a leaver's access can be removed without changing the password for everyone. Keep guests on a separate network that cannot reach internal devices. Old standards such as WEP and WPA should no longer be used.
