Microsoft Passport provides a secure alternative to using passwords for security. The Windows Hello profile configures Microsoft Passport for your Windows 10 Mobile devices so end users can access your data without sending a password.
Protecting devices and accounts with a user name and password creates potential security exploits. Users can forget a password or share it with non-employees, putting your corporate data at risk. Using Passport, Windows Mobile 10 devices securely authenticate the user to applications, Web sites, and networks on the behalf of the user without sending a password. The user does not need to remember passwords, and man-in-the-middle attacks are less likely to compromise your security.
Passport requires users to verify possession of a Windows 10 device before it authenticates with either a PIN or Windows Hello biometric verification. Once authenticated with Passport, the device gains instant access to Web sites, applications, and networks.
Windows Hello requires Azure AD integration to work.
