Apple in late 2020 released a new feature for its devices called private wifi addresses. This feature is available for iOS 14, iPadOS 14, and watchOS 7 devices. The goal of this feature is to offer anonymity when regularly connecting to public wifi access points. As an accountant, your important documents or credentials may be at risk while connected to these hotspots.
The idea of IP addresses is a little better understood by most people. An IP address is a number assigned to a device via the network’s software to connect to the internet. Then there’s the MAC address which is a series of letters and numbers assigned to the hardware. These identifiers are assigned to that device from the factory. Every device with a NIC (network interface card) comes with a hardwired MAC address that is unique to that card and device.
Where Apple comes in
Apple in software updates now allows different individual MAC addresses which are private wifi addresses for each network which the device connects to. By doing this they hope to limit a 3rd party’s ability to track patterns of activity with that device by tracking it across networks.
Besides your MAC address, not much. If your router normally sends a notification when a new device joins, it will say that the device has a private address. You may run into problems also if there are parental controls enabled or the identity of the device is required in order to connect. In those rare cases this feature should be turned off. Also if you find yourself unable to access the internet, even though you’re currently connected, this feature should be disabled. There most likely is some setting on the network is causing interference.

Although more difficult it’s not impossible to change your MAC address on your Android phone and create private wi-fi addresses. The method most similar to Apple’s implementation requires apps like BusyBox or ChameleMAC. Although these apps allow you to change your MAC on the fly, they also require your phone to be “rooted”. Rooting your phone gives you “root-level access” to the operating system and enables power users to modify almost every aspect of the Android. Rooting your phone isn’t for everyone. It’s often been a complicated process and also void many phone warranties.

Quick tips to secure your home network
- Never Use Default Password – Your router’s configuration can be changed with administrator credentials which are commonly never changed from its’ initial setup. All too often these default router credentials can be found with a simple Google search. By looking up either what the Internet Service Provider commonly sets it to or by the router’s make and model a hacker can get right in.
- Use a VPN – Many VPNs (Virtual Private Network) are cross-platform and multiple activations under one annual licensing fee. Masking your internet traffic with a VPN is a great way to remain protected.
- Use Antivirus Software – Having updated antivirus software helps prevent malware from being installed on the computer and reporting your important credentials back to its the creator.
