Yubico announced its plans to support Microsoft's Windows Hello platform back in September at the Ignite conference, with the goal of bringing strong, hardware-based authentication to Windows 10.
Finally, after nearly two months of waiting, the YubiKey for Windows Hello app has landed in the Windows Store. It's a strong solution for retrofitting the additional protection of Windows Hello on systems that don't have built-in support for facial recognition or fingerprint-based sign-in.
The new app requires a YubiKey, Yubico's USB-based device that generates an encrypted, one-time password. Enterprise admins have been using hardware-based authentication for years, making it impossible for phishing attacks and password database breaches to succeed. Even if someone successfully steals your credentials, they can't sign in without proving that they also have the physical device as a second form of identification.
