Apple at Work: Understanding Apple’s Private Wi-Fi Address feature
 
Apple has consistently prioritized user privacy in its design philosophy. 
One of its lesser-discussed yet important features is the Private Wi-Fi 
Address. Introduced to help people maintain their privacy while connected 
to public Wi-Fi networks, this feature aims to help keep information about 
their devices anonymous. But what exactly does it do, and how can you make 
the most of it with your fleet?
 
What Is a Private Wi-Fi Address?
Every device that connects to the internet has a unique identifier called a 
Media Access Control (MAC) address. Typically, this address remains 
consistent, allowing network operators and observers to track your device’s 
activities across various networks. This consistency can be frustrating for 
privacy-conscious users, as it enables data collection that spans multiple 
locations.

Apple’s Private Wi-Fi Address feature changes this by assigning a unique 
MAC address to each Wi-Fi network you connect to. This simple yet powerful 
shift makes it more difficult for network operators to follow your device’s 
behavior as you move from one Wi-Fi network to another.

How does it work?
Apple’s Private Wi-Fi Address is designed to protect users in a few key 
ways:
• Unique MAC Address per Network: Instead of using the same MAC address for 
every Wi-Fi connection, your Apple device generates a distinct MAC address 
for each network. This prevents cross-network tracking and reduces the 
chances of your device being followed across multiple locations.
• Periodic Address Rotation: In some cases, particularly with updated 
software versions, your device may periodically rotate its MAC address to 
further enhance your privacy.
Configuring Private Wi-Fi address
Configuring the Private Wi-Fi Address feature is straightforward depending 
on which Apple device you’re using. Here’s how to do it:

For iPhone, iPad, or iPod Touch (iOS 14 or later):
1. Open the Settings app and tap Wi-Fi.
2. If not connected to the desired network, tap Edit in the upper-right 
corner.
3. Tap the More Info button (usually an “i” symbol) next to the network 
name.
4. Choose Private Wi-Fi Address, then select your preferred option: Off, 
Fixed, or Rotating.

For Mac (macOS Sequoia or later):
1. Go to Apple menu  > System Settings, then select Wi-Fi from the sidebar.
2. Click Details or More Info next to the network.
3. From the Private Wi-Fi Address menu, choose Off, Fixed, or Rotating.

For Apple Watch (watchOS 7 or later):
1. Open the Settings app and tap Wi-Fi.
2. Tap the network name or swipe left and tap More Info if not connected.
3. Select Private Address and choose Off, Fixed, or Rotating based on your 
preference.

For your fleet, you can control this setting as well: Disable association 
MAC address randomization. This is particularly useful in environments 
requiring device authentication based on MAC addresses, but it is not a 
substitute for a strong Wi-Fi password.

Things to consider
While the Private Wi-Fi Address feature is a strong tool for enhancing your 
privacy, there are a few important considerations:
• Network Compatibility: Some networks, especially enterprise or K-12 ones, 
may require a traditional, consistent MAC address for access. If you run 
into connectivity issues, you might need to disable the Private Wi-Fi 
Address for that specific network. If you’re doing this as a way to 
allow/disallow devices on your network, I won’t recommend it, though.
• Security vs. Usability: Keeping the feature enabled protects your privacy 
but might require occasional adjustments for certain networks that don’t 
recognize randomized addresses.

Wrap up:
Apple’s commitment to user privacy is obvious, and the Private Wi-Fi 
Address feature is another way (even if just a small part) to this focus. 
By ensuring that each network receives a unique MAC address from your 
iPhone/Mac/iPad, Apple helps reduce tracking and makes it easier for users 
to protect their data across networks. Whether you’re a privacy-focused 
person or simply want to minimize your digital footprint, this feature is 
worth using.
