Android gives you surprising control over your privacy and security, but some of the most useful settings are easy to overlook. The problem is that some features can sound like they're meant for people who know their way around a network or security console. If you're not particularly technical, it's tempting to leave them alone and assume they're either too complicated or already configured properly.

Fortunately, you don't need to understand all the technical details to take advantage of these protections. Android makes it relatively simple to enable several features that can limit tracking, protect your internet activity, and make your phone more resistant to certain attacks. Some may already be enabled on your device, while others take only a few taps to activate. Once you know where to look, these features become much easier to understand and use.

When scanning for Wi-Fi networks, or connecting to one, your device essentially transmits a unique identifier. Your factory MAC address acts as a digital fingerprint, allowing anyone from network operators to public venues to actually physically track your movements. This can also be used to build a history of your habits, creating a precise profile of who you are and where you go. Turning on MAC address randomization keeps you anonymous and stops potentially malicious third parties from tracking you.

This feature might sound a little daunting if you're not particularly technically inclined. The good news is that on most modern devices, it is active by default . You can, however, double-check that it is active on the network you're connected to by going into your list of available Wi-Fi networks, tapping on the gear icon next to the network, and scrolling down until you see 'MAC address type'.
