Windows Hello is an all-in-one biometric authentication process baked into Windows 10. The May 2020 Update, otherwise known as Windows 10 2004, is expected to be released this week. The first new feature adds Windows Hello PIN sign-in to Safe Mode. The second feature allows you to rely on Windows Hello for signing into your Microsoft account. Microsoft says it’s taking another step forward to make its platform less dependent on traditional passwords. You can use your Windows Hello Face, Fingerprint, or PIN to log in to your Microsoft accounts.
