What is Privacy Mode on Wi-Fi and how does it work?
Privacy Mode on Wi-Fi, also known as Private Wi-Fi Address, is a feature that allows devices to use a random MAC (Media Access Control) address when connecting to a Wi-Fi network. This random address is used instead of the device’s real MAC address, which is a unique identifier assigned to the device’s network interface controller. By using a random MAC address, devices can mask their real identity and make it more difficult for others to track their online activities. This feature is particularly useful when connecting to public Wi-Fi networks, where the risk of being tracked or monitored is higher.
The way Privacy Mode works is by generating a random MAC address for each Wi-Fi network the device connects to. This random address is used for the duration of the connection, and a new address is generated when the device connects to a different network. This makes it challenging for others to associate the device with its real MAC address, thereby enhancing the user’s privacy. It’s worth noting that Privacy Mode is not a foolproof solution and may not protect against all types of tracking or surveillance. However, it can significantly reduce the risk of being tracked and provide an additional layer of privacy when using public Wi-Fi networks.
