What a MAC Address Is and Why You Might Change It

A MAC address is a unique identifier assigned to your phone's network hardware — it looks like a string of letters and numbers separated by colons, such as 00:1A:2B:3C:4D:5E. Your phone broadcasts this address every time it connects to Wi-Fi or Bluetooth, and networks use it to track which device is which on their connection.

You might want to change your MAC address to connect to a network that blocks certain devices, to test network configurations, or to avoid tracking on public Wi-Fi. Android makes this possible, but the method depends on your phone's manufacturer and Android version.

Key Takeaways

  • Most Android phones allow you to randomize your MAC address through Wi-Fi settings without rooting, which is the simplest approach.
  • Some manufacturers like Samsung and Google Pixel offer built-in MAC randomization toggles in their Wi-Fi menus.
  • Permanently changing your MAC address usually requires root access, which voids your warranty and carries security risks.
  • MAC address changes are temporary by default — your phone reverts to its original address when you restart or reconnect to Wi-Fi.

Using Wi-Fi MAC Randomization (No Root Required)

The easiest method on most Android phones is MAC randomization, a built-in feature that assigns a random MAC address to each Wi-Fi network you join. This happens automatically on Android 10 and newer unless you turn it off.

To check or enable this feature: open Settings, go to Wi-Fi, tap the menu icon (three dots) or Advanced, and look for "MAC Randomization" or "Private Address". If it shows "Randomized" or "On", your phone is already changing its address for each network. If it shows "Device MAC" or "Off", toggle it to randomize.

This method does not require rooting your phone and does not void your warranty. The randomized address resets each time you disconnect and reconnect to a network, so it is not permanent — but for most purposes, that is exactly what you want.

Changing MAC Address on Samsung Phones

Samsung phones running One UI 3.0 and newer have a dedicated MAC randomization control. Open Settings, tap Connections, select Wi-Fi, tap the menu icon, and choose Advanced. Look for "MAC Address Type" or "Private Address" and set it to Randomized.

On older Samsung models, the setting may be labeled differently or located under Wi-Fi Settings > Advanced. If you cannot find it, your phone likely uses the standard Android randomization method described above, which is already active by default.

Samsung does not offer a built-in tool to permanently change your MAC address without rooting. If you need a permanent change, you would need to root your device and use a third-party app — a process that carries risks and is rarely necessary.

Changing MAC Address on Google Pixel Phones

Google Pixel phones running Android 12 and newer include a straightforward MAC randomization feature. Open Settings, go to Network and Internet, select Wi-Fi, tap the menu icon, choose Advanced, and toggle "Use Private Address" on.

This setting applies to each network individually, so you can randomize your address on some networks and use your device MAC on others. The change takes effect the next time you connect to that network.

Like Samsung, Google Pixel phones do not offer a permanent MAC address change without rooting. The randomization approach is the standard method Google recommends for privacy on public networks.

Changing MAC Address on Other Android Phones

Phones from manufacturers like OnePlus, Motorola, and others typically follow the standard Android approach. Open Settings, go to Wi-Fi, tap the menu or Advanced options, and look for "MAC Randomization", "Private Address", or "Use Random MAC". Toggle it on if it is not already enabled.

If your phone does not show this option, it may be running Android 9 or earlier, which does not include randomization by default. In that case, you can still connect to networks normally — you straightforward cannot change your MAC address without rooting.

Check your phone's manufacturer website or support page if you cannot locate the setting. The exact menu path and label vary by skin and version, but the feature is present on nearly all phones from 2020 onward.

Permanently Changing Your MAC Address (Root Required)

If you need a permanent MAC address change that persists across restarts and network switches, you must root your Android phone and use a third-party app. This process voids your warranty, can expose your phone to security vulnerabilities, and may prevent you from using banking apps or other services that detect rooted devices.

Apps like BusyBox and Xposed Framework allow MAC spoofing on rooted phones, but they require technical knowledge to install and configure. Rooting also varies by phone model — some are straightforward to root, others are nearly impossible. Unless you have a specific technical reason for a permanent change, MAC randomization is the safer and simpler choice.

If you do root your phone, research your specific model thoroughly before starting. Mistakes during rooting can brick your device, and you will lose manufacturer support if something goes wrong.

What Happens When You Change Your MAC Address

When you randomize your MAC address, networks see your phone as a different device each time you connect. This prevents the network from building a profile of your device across multiple visits — useful on public Wi-Fi where tracking is a concern.

However, randomization does not hide your identity if you log into an account or service. A coffee shop can still see what you do online if you sign into your email or social media. MAC randomization only prevents device-level tracking, not user-level tracking.

Your phone's original MAC address is still stored in its hardware and can be viewed in Settings under About Phone or Device Information. Changing the MAC address does not alter the hardware itself — it only changes what your phone broadcasts to networks.

Frequently Asked Questions

Will changing my MAC address let me bypass network restrictions?

Yes, if a network blocks your device by MAC address, randomizing your address will let you connect as a new device. However, if the network blocks you by username or account, changing your MAC address will not help. Some networks also track by IP address or device fingerprinting, which MAC changes do not affect.

Does MAC randomization slow down my internet?

No. Randomizing your MAC address has no impact on speed or performance. It only changes the identifier your phone broadcasts — the actual connection and data transfer work exactly the same way.

Can I set a specific MAC address without rooting?

No. Without root access, you can only randomize your address, not set it to a specific value. Android's built-in randomization chooses a new address automatically each time you connect to a network.

Will my phone remember which networks I have randomized?

Your phone remembers your saved Wi-Fi networks and their passwords, but it generates a new random MAC address each time you connect. If you turn off randomization for a specific network, your phone will use your device MAC on that network instead.

What if I cannot find the MAC randomization setting?

Check that you are running Android 10 or newer — older versions do not include this feature. If your phone is up to date, the setting may be under Wi-Fi Advanced, Network Settings, or Privacy. If it is still not there, your manufacturer may have hidden it or named it differently — check your phone maker's support site for your specific model.
