Microsoft just turned on the ability to securely sign in with your Microsoft account using a standards-based FIDO2 compatible device—
This combination of ease of use, security, and broad industry support is going to be transformational both at home and in the modern workplace. Every month, more than 800 million people use a Microsoft account to create, connect, and share from anywhere to Outlook, Office, OneDrive, Bing, Skype, and Xbox Live for work and play. And now they can all benefit from this simple user experience and greatly improved security.
Watch this quick video showing how it works:
Microsoft has been on a mission to eliminate passwords and help people protect their data and accounts from threats. As a member of the Fast Identity Online (FIDO) Alliance and the World Wide Web Consortium (W3C), Microsoft has been working with others to develop open standards for the next generation of authentication. Microsoft is the first Fortune 500 company to support password-less authentication using the the WebAuthn and FIDO2 specifications.
