There's one downside to this approach: since you always use the same address when connecting to a particular network, an adversary can learn when certain devices connect to specific networks. Therefore the system can still recognize you, and you don't have to pay twice. ![]() And if you reconnect to this network at a later point in time, Windows will reuse the previously generated address. The first time you connect, Windows will generate a random MAC address. For example, let's say you want to pay for Wi-Fi access, and they authenticate you based on your MAC address. Interestingly, Windows avoids this issue by always using the same random address every time itĬonnect to a specific network. Using a random MAC address to connect to a network can cause problems if users are authenticated (i.e., recognized) based on their MAC address. In this aspect Windows 10 offers better privacy than Apple. ![]() In contrast, Apple only uses random addresses when searching for nearby networks, and it falls back to its original address when connecting to a network. What's very interesting about Microsoft's approach is that it also uses random MAC addresses when connecting to a wireless networks. As you can see, I have it enabled on my laptop. ![]()
