+We're excited to announce the general availability of hybrid cloud Kerberos trust, a new Windows Hello for Business deployment model to enable a password-less sign-in experience. With this new model, we’ve made Windows Hello for Business much easier to deploy than the existing key trust and certificate trust deployment models by removing the need for maintaining complicated public key infrastructure (PKI), and Azure Active Directory (AD) Connect synchronization wait times. For more information, see: [Hybrid Cloud Kerberos Trust Deployment](/windows/security/identity-protection/hello-for-business/hello-hybrid-cloud-kerberos-trust).
