Windows Hello allows Windows 10 users to have an alternative way to sign in to their devices and apps using fingerprint, iris scanners, or facial recognition.

This biometric technology allows Windows 10 users to authenticate themselves for secure login to devices, applications, online services and networks using their biometric characteristics, instead of the conventional way with a username and password. By general admission, this way of identifying the user is far more user-friendly and more reliable, especially for accessing key systems, services and data.
“ Windows Hello solves a couple of existing problems: security and ease of use,” said Patrick Moorhead, president and principal analyst at Moor Insights & Strategy. “Traditional username and password credentials are insecure and sometimes difficult to remember, so some users use easier passwords or write them down in insecure locations.
It's quite common for users to choose the same password (or easy variations) across different websites and apps. Windows Hello and similar biometric authentication applications like Apple 's Face / Touch ID are designed to allow for a more secure authentication method based on technology that is harder to crack.
The new system greatly reduces malicious attacks by removing the need for more insecure credentials. “ Windows Hello enables Microsoft account authentication with Fast Identity Online ( FIDO ) that links the user to their biometrics using 3-D lighting to model the user’s face and anti - spoofing techniques as an additional method of protection,” said Anoosh Saboori , senior program manager leader at Microsoft .
