How to Activate Microsoft Office Without a Product Key (Legal and Safe Methods)
Activating Microsoft Office without a product key is possible in a legal and safe way. Microsoft provides several official methods that allow users to activate or use Office without entering a traditional key. These options work for Office 2019, Office 2021, and Microsoft 365, depending on eligibility.

If Microsoft Office was purchased online or came preinstalled on your computer, a product key may not be required.
Steps

This method works if the license is already linked to your Microsoft account and is common on new laptops.
