iOS 14 Beta 2 brought an extremely useful feature for improving Wi-Fi privacy & security. From now on your iPhone and iPad that run iOS 14 and iPadOS 14 respectively will use a random MAC address for every new Wi-Fi network you join. This will prevent the admin of the hotspot or server from tracking your device.
As I understood, the unique random MAC will be used for each network. This will be especially useful when connecting to public hotspots because from now on you can opt to not expose the real physical address of your Wi-Fi module.
Wi-Fi Privacy Warning: What is This?
If you see the “Privacy Warning” notification under the Wi-Fi network name on your iPhone or iPad, this means that the MAC randomization is disabled and the administrator of the hotspot which you are currently connected to is able to view (save and track) the real address of your Apple device. I first saw this notification after I installed iOS 14 Beta 2 on my iPhone 11 and connected to my home network.
How to remove the “Privacy Warning” Under Your Wi-Fi Network on iPhone / iPad
Here is what to do if you want to get rid of the notification below your wireless network name:
Step 1. Go to Settings > Wifi and open the network properties by tapping on its name.
Step 2. Enable the “Private address” option.
Step 3. Reconnect to your Wi-Fi Hotspot in any way: either by temporarily putting your device to Airplane mode or by disabling and re-enabling the Wi-Fi.
P.S. sometimes I have to wait or repeat the steps until the Wi-Fi “Privacy Warning” notification disappears.
Tell us in the comments, how the things are on your iPhones/iPads with iOS 14/iPadOS 14 Beta. Thank you in advance.
Update: in September 2020, immediately after the release of iOS 14, many users encountered the Weak Security warning on their devices.
