Your MAC address can be used to track you on and across Wi-Fi networks. Spoofing it can help improve your privacy.
A MAC address (media access control address) is a unique 12-digit hexadecimal number assigned to every device connected to the network. When you connect to any network (Ethernet or Wi-Fi), your device's MAC address is visible to the router, and usually to other devices on the same LAN network.
MAC Spoofing changes your MAC address every time you disconnect from a network, so next time you connect, your MAC address will be different. This makes you appear as a new, never-before-seen device.
Your favorite chain of coffee shops probably knows exactly which locations you visit, simply by tracking your device’s MAC address when you use their Wi-Fi. With MAC Spoofing, you can stop this tracking in its… tracks.
You can also rotate your MAC manually using a button in the app, just keep in mind that you will get disconnected from the network and will need to reconnect.
