Redeeming the product key is the first thing that needs to be done and for this you need to navigate to the mcafee.com/activate platform. When you redeem the McAfee product key, it gets linked to your account for the future usage. For this purpose, make sure you have a McAfee account. In case you do not have one, then you may need to sign up or register on the official portal.
After this, you need to locate the product key, the method for which is based on the mode of your purchase. Those who have purchased it from Amazon or any other online retailer can look for it in the confirmation/welcome email. If you have purchased it from a nearby retailer, then it should be imprinted on the retail card.
Once you locate the key, go to the given website, enter the activation code in the provided space and enter your McAfee account details and you are done.
