Microsoft indicated on Monday that it’s possible to use devices based on the Fast IDentity Online 2.0 (FIDO2) protocol with a Microsoft account and Windows 10 version 1809 to verify user access, obviating the need for a password.

The capability works with desktop and mobile devices, permitting access to applications such as Microsoft Office, Outlook and Skype, Microsoft’s announcement indicated. A Microsoft document, though, stated that “this functionality is not available yet on phones.” Organizations can use a FIDO2-based device or they can use Windows Hello, Microsoft’s biometric identity solution, with a Microsoft account. The FIDO2 devices supported might be a USB thumb drive with a fingerprint reader, or some other kind of security key.

The FIDO2 capability requires using the Windows 10 October 2018 Update (version 1809), as well as the Microsoft Edge browser. Despite its rerelease earlier this month, Windows 10 version 1809 may still be blocked for some users because of new problems found with Intel display drivers, and a few other problems, as listed in Microsoft’s Windows 10 Update History page.
