To sign into a Windows 10 device with a fingerprint, the device must have a fingerprint reader. The user's biometric data is encrypted and remains on the biometric-capable device. Hello also releases a stored credential that is used as a second authentication factor by Microsoft Passport. Passport gives the user access to services that support that supports the Fast ID Online ( FIDO) standard, including Active Directory. If more than one user works with a specific device, the engine can differentiate between users. The user must also set up a PIN, which serves as a backup plan if any of the biometric authentication measures fail. When the end user signs in, Windows Hello identifies and authenticates the user and gives the user access to the Windows operating system. To get started with Microsoft Windows Hello, the end user must use a wizard to teach the device to recognize the user's biometric credentials.

Microsoft Windows Hello is a biometric identity and access control feature that supports fingerprint scanners, iris scanners and facial recognition technology on compatible devices running Windows. The Hello engine allows users to securely log into devices that have the necessary hardware components without having to type a password.
