How to Change (Spoof) MAC Address on Chromebook: 2026 Guide

To change your MAC address on a Chromebook, you have two options. For simple privacy, go to Settings > Network > Wi-Fi > [Your Network] > Privacy and enable “Use Randomized MAC Address.”

However, if you need to “spoof” a specific MAC address (to bypass a router filter, for example), you must enable Developer Mode and use the Crosh command line.

In 2026, ChromeOS is locked down tight, so changing hardware identifiers requires root access.

Method 1: MAC Randomization (No Dev Mode)

If you just want to hide your identity on a coffee shop Wi-Fi, use this built-in 2026 feature. It protects you from tracking without requiring any hacking.

Method 2: Command Line Spoofing (Requires Dev Mode)

If you need a specific address (e.g., cloning an old laptop’s MAC to bypass a router block), you must be in Developer Mode.

Step 1: Open Crosh Shell

Press Ctrl + Alt + T to open the terminal. Then type the following to enter the Linux shell:

Step 2: Identify Your Interface

Type this command to find your Wi-Fi interface name (usually wlan0 or mlan0):

Step 3: Shut Down the Interface

You cannot change the MAC address while the Wi-Fi card is active. Turn it off:

Step 4: Spoof the Address

Replace 00:11:22:33:44:55 with the MAC address you want to use:

Step 5: Turn It Back On

Note: This change is temporary. If you reboot your Chromebook, it will revert to the original hardware MAC address.
