Wi-Fi security types are different ways to protect your wireless network from unauthorised access. When you set up a Wi-Fi network, you can choose from different security types such as WEP, WPA, WPA2, or WPA3. These security types are like locks on a door - they help to keep your Wi-Fi network secure and prevent unauthorised access. WEP is an older and less secure security type that can be easily hacked, while WPA and WPA2 are more secure and use better encryption methods to protect your data. WPA3 is the latest and most secure Wi-Fi security type that provides even stronger encryption and better protection against common attacks. By choosing a secure Wi-Fi security type, you can help to keep your wireless network and data safe from hackers and other unauthorised users.
