A software product key is a unique code that activates and validates certain software applications. It proves that a user has legally purchased the software and is entitled to use it. Product keys are often used for software that is licensed on a per-computer basis, such as Microsoft Office.
There are various ways to buy a Microsoft Office product key. One can purchase it directly from Microsoft’s website, or from authorized retailers, both online and offline. When buying from Microsoft’s website, users can choose between a one-time purchase or a subscription-based model. Authorized retailers may offer discounts or promotions on product keys, so it’s worth comparing prices before making a purchase.
