iOS 14: How to Block Network Operators from Tracking Your iPhone or iPad on Wi-Fi Networks
In iOS 14, your iPhone or iPad can use a different MAC address with each Wi-Fi network to prevent network operators from tracking your phone on different Wi-Fi networks.
To communicate with a Wi-Fi network, a device must identify itself to the network with a unique network address called a media access control (MAC) address.
If your iOS device always uses the same Wi-Fi MAC address on all networks, it means that network providers and other network watchers can more easily relate this address to network activity and the location of the network. device over time.
This allows for some sort of user tracking or profiling, but you can prevent this from happening by instructing your iOS device to use a different MAC address for each Wi-Fi network it connects to. Here is how to do it.
- Launch the application ” Settings » on your iPhone or iPad.
- Press the key Wireless.
- Touch the circular button Info (i) next to the Wi-Fi network you want to use.
- Toggle the switch next to Private address on the green ON position.
If you have an Apple Watch, you can activate the same function in the app ” Parameters’ of your watch: Tap Wireless, tap on the network that you have joined (if you have not yet joined it, slide over it and tap on the three points), then tap Private address.
Note that Apple notifies you when you connect to a Wi-Fi network that does not use the private address feature.
