Windows Hello is a more secure way to log in to your Windows 10 device without having to remember your password. The futuristic login technology uses biometric authentication, which makes it faster, safer, and easier to access your computer with your fingerprint or facial recognition while providing enterprise-grade security.

You can use this biometric data to connect to online devices, applications, or networks. You can also pair a Bluetooth device, such as a smartphone, with your computer and use the Windows Hello dynamic lock feature to automatically lock your computer.

As great as this service sounds, sometimes Windows Hello fingerprint doesn’t work because of hardware issues, system corruption, software conflicts, improper settings, or faulty, outdated, or incompatible drivers.

If Windows Hello doesn’t work, perhaps after an update or other change to your computer, try some of the workarounds described in this guide to get it working again.

Why doesn’t Windows Hello work in Windows 10?

Old drivers for imaging and biometric devices: If the drivers for necessary devices, such as webcams, fingerprint sensors, and iris scanners, are old and outdated, Windows Hello will not start. Updating the Device Manager solved the problem for many users.

PIN login disabled: As with the first cause, a recent Windows update may have disabled the PIN login authority you previously had. Make sure you re-enable it in the registry editor.

Trusted Platform Module (TPM) is not configured on your machine: TPM must be configured and running on the machine to allow PIN logon for domain users. Users solved the problem by installing it on their computers.
