Wi-Fi Protected Access (WPA), Wi-Fi Protected Access II (WPA2) and Wi-Fi Protected Access III (WPA3) are three security protocols developed by the Wi-Fi Alliance to protect wireless computer networks.

📷 The encryption protocol used by WPA2 was launched in 2004 and is significantly more effective in protecting privacy and integrity than the corresponding encryption protocol used by WPA.

Wi-Fi devices certified since 2006 support both WPA and WPA2 security protocols.

👉🏼👉🏼 Warning! The new WPA2 may not work with devices that are a few years old.

In January 2018, the Wi-Fi Alliance announced WPA3 which brings further security improvements that make unauthorised network access attempts more difficult. However, an attack against this protocol was discovered in 2019 and some of the vulnerabilities remain unresolved, it is recommended to continue using WPA2 until WPA3 is thoroughly tested.

✅ Don't forget: Your business and home network must be kept secure to prevent unauthorised access. The best way to do this is by properly setting strong passwords and enabling WPA2 as an authentication method in the settings of your network devices.
