What is a MAC address and why would I want to change it?
A MAC address (Media Access Control address) is a unique identifier assigned to network interfaces for communications on a physical network segment. It is used by routers to identify devices that connect to a WiFi network. By default, each device has a manufacturer-assigned MAC address that remains constant and can be tracked by network administrators or malicious actors.
Changing your MAC address can enhance your privacy and security while using public or unsecured WiFi networks. It can prevent tracking, protect your personal information, and reduce the chances of being targeted by hackers. By disguising your true device identity, you can minimize exposure to unwanted surveillance and data collection.
