A Microsoft account is what you use for almost everything you do with Microsoft devices and services. Itâs an email address and password that you use to sign in to Skype, Outlook.com, OneDrive, Windows Phone, and Xbox LIVE â and it means your files, photos, contacts and settings can follow you to any device.
It keeps you connected to the people you care about on Facebook, Twitter, LinkedIn and other services. It all just works, wherever you go. One of our principles is that we should adapt to how you want to work, not vice versa. This is why we allow you to use any email address to sign in to your Microsoft account. Weâve also heard from you that over time things change with your accountâyou might get married, start a new job, move or any number of life events that make you want to change your email address.
