A Microsoft account (MSA) is a single sign-on personal user account that lets you access various Microsoft services and devices with one set of credentials. It is used for consumer Microsoft services like Outlook.com, Xbox, Windows PCs, Microsoft Office, Skype, and more. You can create a Microsoft account using an existing email address or by signing up for a free Microsoft email account such as Outlook.com. The account enables access to Microsoft apps, services, and games, and supports features like two-factor authentication and login via Microsoft Authenticator or Windows Hello. Microsoft accounts are separate from work or school accounts, which use Azure Active Directory and are typically managed by organizations. You can manage your account details, reset passwords, view billing info, and customize settings at the Microsoft account website (account.microsoft.com). This account is essential for seamless use of Microsoft ecosystems across devices and web services.
