Office 2021 Professional Plus – Bind Licence for Your Microsoft Account
A bind key is redeemed at microsoft.com/redeem and then lives permanently inside your Microsoft account. That means you can reinstall Windows, move to new hardware, or download Office again at any time without hunting for a product key. This is the most durable Office 2021 licence we sell.
Bind Key vs Online Activation Key
| Stored in your account | Yes – visible under your Microsoft services page |
|---|---|
| Survives a Windows reinstall | Yes – sign in and reinstall |
| Download source | Directly from your Microsoft account |
| Renewal cost | None – one-time purchase |
How to Redeem Your Bind Key
- Complete checkout – your key arrives by email within minutes.
- Go to microsoft.com/redeem and sign in to your Microsoft account.
- Enter the key to attach the licence to your account.
- Open account.microsoft.com/services and download Office 2021.
- Install, launch any application, and sign in with the same account to activate.
Redeem the key against the account you actually intend to keep – once attached, the licence cannot be moved to a different Microsoft account.
