For example, data about whether people sign in with their face, iris, fingerprint, or PIN the number of times they use it and whether it works or not is all valuable information that helps us build a better product. To help us keep things working properly, to help detect and prevent fraud, and to continue improving Windows Hello, we collect diagnostic data about how people use Windows Hello. When you set up Windows Hello biometrics, it takes the data from the face camera, iris sensor, or fingerprint reader and creates a data representation-or graph-that is then encrypted before it’s stored on your device.
Windows does not store pictures of your face, iris, or fingerprint on your device or anywhere else. If it’s the right choice for you, you can rest assured that the info that identifies your face, iris, or fingerprint never leaves your device. Even if your Windows device can use Windows Hello biometrics, you don’t have to. Windows Hello lets you sign in to your devices, apps, online services, and networks using your face, iris, fingerprint, or a PIN. Select PIN (Windows Hello), and then select Change PIN.
