Deactivate my Malwarebytes Premium license key

We recommend deactivating your license key if:

  • you are transferring your license key to a new device.
  • you need to repair, replace, or sell your device.
  • your device has been lost or stolen.


There are two ways to deactivate your license key through My Account or within the Malwarebytes product.


Deactivate in My Account

If you purchased your Premium license key from the Malwarebytes store, you can log in to My Account to deactivate your license key. 


When you deactivate your license key, the key is disconnected from your devices.  If you turn on the device within 24 hours of deactivating, your device is automatically reconnected to your license key.


  1. Connect your device to the Internet.
  2. Uninstall Malwarebytes software from your device to prevent the software from automatically reactivating.
  3. Using your browser, go to My Account to deactivate your license key.
    1. Enter your email and password for My Account, then click SIGN IN.
      If you do not have a My Account login, see how to  Set up My Account.
    2. Click the Subscriptions tab.
    3. Locate the license key you are attempting to deactivate, then click Deactivate all.
    4. To confirm you would like to deactivate your devices, click CONTINUE.
