passwordless sign-ins

Microsoft is integrating Windows Hello Enhanced Sign-in Security (ESS) with compatible external fingerprint readers, allowing passwordless sign-ins on a wider range of Windows 11 devices. This update enhances biometric authentication security by utilizing hardware-backed protections such as the Trusted Platform Module (TPM) and Virtualization-Based Security (VBS), which isolate sensitive biometric data from malware and unauthorized access. Previously, only devices with integrated fingerprint sensors could fully utilize ESS, but the recent update (KB5101684) enables external fingerprint readers to function within the ESS framework. The update is being rolled out for Windows 11 versions 25H2 and 24H2, and users can set up fingerprint authentication by connecting a compatible reader. This advancement aids IT administrators in implementing passwordless authentication while maintaining security protocols.
