Troubleshooting MAC Randomization on BYOD Devices

"Device has not been seen" on BYOD Devices

Parents with a Family Zone account and a child enrolled at a Linewize partner school may receive an email stating the “Device has not been seen in 14 days”.  This can happen when your child’s device has MAC Randomization (or MAC Privacy) turned on when connecting to the school network. Your school needs your child’s device to use the unique MAC address associated with it instead of a randomized one. This ensures a false positive email for "Device has not been seen in 14 days" isn't generated and students are not incorrectly authenticated as another student.

Your child's school may ask you to confirm if MAC Randomization is enabled on child's device by signing into your Family Zone account and checking if your child has multiple devices with the same name.

MAC Randomization does not bypass Family Zone filtering.

Frequently Asked Questions

What is a MAC Address?

Not to be confused with an Apple Mac computer, a Media Access Control (MAC) address is a unique identifier assigned to the network connections (LAN, Wireless, and Bluetooth) on a computer, phone or tablet.

What is MAC Randomization?

MAC Randomization and MAC Privacy have existed for several years. They work when a computer, phone or tablet uses a different MAC address each time it connects to a network. Device manufacturers like Apple and Google use this feature to improve privacy. The randomly changing identity reduces the risk of tracking a device, user, and location through the device's unique MAC address.
