What’s New in 18945

Extending support for FIDO2 security keys to hybrid environments 

We’re adding the capability for modern passwordless credentials, such as FIDO2 security keys, to authenticate and provide seamless Single Sign-On (SSO) to on-premises environments.  Please refer to this blog entry that discusses this capability for cloud environments.
