How to Find the Office Home and Student 2021 Product Key on Mac
Question details
The user needs to locate their product key for Microsoft Office Home and Student 2021 on a Mac, often required for reinstallation or after significant hardware changes.
- Product
- Microsoft Office Home and Student 2021
- Device & OS
- Mac
- Scenario
- Reinstalling the software or reactivating the license after a hardware replacement, such as a new motherboard.
- Observed behavior
- The 25-character product key is not visible because the license is automatically linked to the user's Microsoft account after the initial redemption.
Ensure you have the login credentials for the Microsoft account originally used to purchase or redeem your Office 2021 license.
Reinstall and Activate via Your Microsoft Account
Because your Office 2021 license is digitally linked to your account, you do not need the original product key to reinstall and activate the software on your Mac.
After the initial setup, Microsoft no longer displays the full 25-character product key. Instead, your license is securely bound to your Microsoft account. You can manage your installation entirely online.
Open a web browser on your Mac and navigate to account.microsoft.com. Log in with the account associated with your Office purchase.
Click on the 'Services & subscriptions' tab at the top of the page. You can also check 'Order history' to verify the purchase.
Locate 'Office Home and Student 2021' in your list of active products and click the 'Install' button to download the Mac installer package.
Once installed, open Word or Excel on your Mac. When prompted, sign in with the same Microsoft account to automatically activate your license without entering a key.
Contact Microsoft Support for Hardware Changes
If you recently replaced your Mac's motherboard or other major hardware, you may receive an activation limit error that requires manual intervention by support.
Switch to WPS Office for Mac to Avoid Activation Hassles

- 1. Download the App: Visit the WPS Office website and download the macOS version.
- 2. Install on Mac: Open the downloaded package and drag WPS Office into your Applications folder.
- 3. Start Working: Launch WPS Office and instantly open your existing Microsoft Office files without entering a product key.
Frequently Asked Questions
Can I view my 25-character product key in my Microsoft account?
No. Once Office 2021 is linked to your account, the actual 25-character key is hidden for security reasons. You activate the software simply by signing in with your Microsoft account credentials instead of entering the key manually.
What happens if I forget which Microsoft account is linked to my Office 2021 purchase?
You will need to sign in and check all your personal Microsoft accounts under the 'Services & subscriptions' page. If you still cannot find your license, contact Microsoft Support and provide your original purchase receipt so they can help locate your account.
Can I transfer my Office Home and Student 2021 license to a new Mac?
Yes, but you must first uninstall the software from your old Mac. Then, sign in to your Microsoft account on the new Mac, download the installer, and activate it. If you encounter an 'activation limit reached' error, you will need to contact Microsoft Support to clear the previous device registration.
