What is a Microsoft account?
A Microsoft account is an email address and password that you use with Outlook.com, Hotmail, Microsoft 365, Office, OneDrive, Skype, Xbox, and Windows.
When you create a Microsoft account, you can use any email address as the user name, including addresses from Yahoo! or Gmail. After you associate this account with your Office product, if you ever need to reinstall the apps, you'll use this Microsoft account instead of a product key to install and activate Office.
Should I create a new Microsoft account?
If you already sign in to Outlook.com, Hotmail, OneDrive, Skype, Xbox, and Windows, you already have a Microsoft account. Use that account instead of creating a new Microsoft account.
Why do I need a Microsoft account?
Your Microsoft account takes the place of a product key and makes it easier to reinstall Office. You must have a Microsoft Account to use Office on your Office Pre-installed device.
Where's my product key?
No product key is provided or needed. To reinstall Office or to manage your Microsoft 365 subscription, use your Microsoft account to sign in to the Services & subscriptions page of your Microsoft account dashboard.
