Part 3: Can I activate Microsoft Office 2021 without a Microsoft account?

For those seeking to activate Microsoft Office 2021 without a Microsoft account, please be aware that there doesn't seem to be an official or supported method to do so. Microsoft typically requires a Microsoft account for activation. Beware of unofficial or third-party methods, as they may pose security risks and may not be legal.

To ensure a secure and legitimate activation, it's best to follow Microsoft's official procedures, which involve a valid product key and a Microsoft account. This approach ensures compliance with licensing agreements and provides access to updates and support from Microsoft.

Part 4: How to activate Microsoft Office 2021 in other methods?

Method 1: Using Product Key

Step 1: Begin by visiting and sign in using your Microsoft account credentials.

Step 2: Input the 25-character product key that came with your purchase.

Input key

Step 3: Choose your country and preferred language, then proceed by clicking "Next."

Click Next

Step 4: You will be directed to the Microsoft Services and Subscriptions Page.

Step 5: On this page, locate the product you have just activated and click on "Install" to initiate the setup download.

Click Insstall

Step 6: Execute the setup file to install Office on your computer.

Step 7: When prompted, log in using the same Microsoft account.

This is the official and supported way to activate Microsoft Office 2021. If you have a product key, this is the method that I recommend.

Method 2: Using Office Activation Wizard

When a copy of Office expires or is not activated, the Activation Wizard will prompt you. If you've changed hardware, this wizard can help resolve activation issues.

Follow the prompts in the Activation Wizard. You can choose to activate over the internet or contact Microsoft Support for phone activation.

Follow the prompt

The Office Activation Wizard is a tool that Microsoft provides to help you activate your Office installation. This method is also official and supported by Microsoft.

Method 3: Using KMS Activators

Step 1: Commence by downloading the KMSPico tool from a reputable source you trust.

Step 2: Unzip the downloaded file and run the KMSPico.exe application with administrator privileges.


Step 3: Patiently wait as the user interface loads, and then click on the "Active Office" option to initiate the activation process.

Step 4: Allow the activation to conclude. You should eventually see a confirmation message reading "Successfully Activated."


KMS activators are third-party tools that can be used to activate Microsoft Office (including Office 2010-Office 2016, Office 2019-Office 2021) without a product key. However, these tools are often not reliable and can be risky to use. There is a risk that they may contain malware or viruses. Additionally, Microsoft may eventually block these tools, making them unusable.
