If you are using Windows 10 October 2018 Update (version 1809), Microsoft Edge now supports password less authentication to sign-in to MSA accounts using WebAuthn and FIDO2 specifications. This makes Microsoft the first company to support password free authentication.
Let's discuss about password-less authentication and how to configure your Microsoft account to sign-in using Windows Hello and/or Security Keys.
What is WebAuthn?
WebAuthn is a password free sign-in standard, which enables sign-in to websites using biometrics. This could be using Windows Hello (face recognition, fingerprint reader or PIN) or using FIDO2 compliant Security Keys. Point to note that, WebAuthn is also being supported by major browsers like Google Chrome and Mozilla Firefox.
Alex Simons, the Corporate Vice President of Program Management at Microsoft Identity Division, in a blog post mentioned that "Microsoft is the first Fortune 500 company to support password-less authentication using the the WebAuthn and FIDO2 specifications, and Microsoft Edge supports the widest array of authenticators compared to other major browsers.".
What is Windows Hello?
Windows Hello is a more personal way to sign-in to your device or your account on the web using your fingerprint, face or a secure PIN. This helps you to log-in to your account without having to type in a password.
What is FIDO2 compliant Security Key?
FIDO2 compliant Security Key is a physical device that you can use to sign-in to your account without using your username and password. Using of Security Keys are more secure as it's been used in addition to a biometric authentication. If anyone get your security key, they won't be able to sign-in without the PIN or fingerprint that you have already configured.
You can purchase security keys from retailers. Yubico's YubiKey and the Feitian BioPass key are some examples of FIDO2 compliant security keys.
