If you signed in with your Microsoft account when you set up your phone, hooray!
If not, that's OK—you can sign in any time. And if you're not quite sure what a Microsoft account is, we'll tell you.
Have you ever used Outlook.com, Hotmail, Office 365, OneDrive, Skype, Xbox, or Windows? The email address and password you use for any of those services is your Microsoft account. If not, it's easy to create a free account with your email address or phone number at account.microsoft.com.
Your Microsoft account gives you access to apps and games from the Windows Store, and lets you see your settings and other stuff across multiple Windows 10 devices. Read more about the benefits of a Microsoft account.
If you've already added a Microsoft account, you'll see that info here. If you haven't, select Add a Microsoft account.
If you have a problem signing in or forgot your password, try the Microsoft account FAQ.
