Fido2 windows hello5/10/2023 ![]() And because FIDO2 generates unique private/ public key pairs for each Identity Provider, this means they will not be able to link your key to your account. When an Identity Provider is hacked, the hacker only finds a list of useless public keys and no passwords. AAD can then verify the signature with your public key and allow logon.Īn advantage of this solution is there are no passwords stored at the identity provider. ![]() The challenge is signed with the private key (which is stored on the FIDO2 key) and the result of that signature is send back to AAD. With the challenge, AAD wants to determine if the user is who he claims to be. When the user needs to authenticate to Azure AD (AAD) for sign-in to the Windows 10 device or sign-in to Office 365 via a browser, AAD provides the user a challenge. The public key is provided to the identity provider (in this case Azure AD) and the private key remains on the device (the FIDO2 security key). FIDO2 makes use of a public/ private key pair for authentication. This is accomplished by sign-in in without using a username and password passwordless. The goal of FIDO is to make the sign-in proces more secure and simplified. Supported FIDO2 security keys, provide a passwordless sign-in option, to Saas apps (like the Office 365 portal) or to an Azure AD joined Windows 10 device.įIDO stands for Fast Identity Online, an open standard to sign-in safely to SaaS apps and computers. This passwordless sign-in feature for Windows 10 is made possible by the support in Azure AD for FIDO2 security keys, which was announced (in preview) by Alex Simons back in July 2019. If you have already read my previous post about the Yubico key, you might want to move on to the End-user experience part of the post. More on the Bio versions later in the post, first let`s have a look at what passwordless authentication is and the requirements are. I received multiple keys from Feitian for testing, some standard keys with and without NFC, but I also received a few Bio versions. This time I tested several FIDO2 keys from Feitian. For that post I tested a FIDO2 security key from vendor Yubico. A few weeks ago I wrote a post with the same subject, passwordless authentication to Windows 10 with FIDO2 security keys.
