![]() This level of effort typically applies to organizations that only need their users to sign in to Microsoft 365, SaaS apps, and other Azure AD-based resources. Password hash synchronization requires the least effort regarding deployment, maintenance, and infrastructure. Detailed considerations Cloud authentication: Password hash synchronizationĮffort. Organizations can fail over to Password Hash Sync if their primary sign-in method fails and it was configured before the failure event.Īzure AD Identity Protection require Azure AD Premium P2 licenses. Azure AD Identity Protection requires Password Hash Sync regardless of which sign-in method you choose, to provide the Users with leaked credentials report.Multi-site on-premises authentication solution.Sign-in using third-party authentication solution.Sign-in features not natively supported by Azure AD:.If you need to apply, user-level Active Directory security policies such as account expired, disabled account, password expired, account locked out, and sign-in hours on each user sign-in, Azure AD requires some on-premises components.Azure AD can hand off user sign-in to a trusted authentication provider such as Microsoft's AD FS.Azure AD can handle sign-in for users without relying on on-premises components to verify passwords.It helps you determine whether to deploy cloud or federated authentication for your Azure AD hybrid identity solution. The following section helps you decide which authentication method is right for you by using a decision tree. The authentication system can provide other advanced authentication requirements, for example, third-party multifactor authentication. When you choose this authentication method, Azure AD hands off the authentication process to a separate trusted authentication system, such as on-premises Active Directory Federation Services (AD FS), to validate the user's password. For more information on the actual pass-through authentication process, see User sign-in with Azure AD pass-through authentication. The servers validate the users directly with your on-premises Active Directory, which ensures that the password validation doesn't happen in the cloud.Ĭompanies with a security requirement to immediately enforce on-premises user account states, password policies, and sign-in hours might use this authentication method. Provides a simple password validation for Azure AD authentication services by using a software agent that runs on one or more on-premises servers. For more information on the actual process of password hash synchronization, see Implement password hash synchronization with Azure AD Connect sync.Īzure AD Pass-through Authentication. ![]() Passwords are never stored in clear text or encrypted with a reversible algorithm in Azure AD. These factors are different for every organization and might change over time. To choose an authentication method, you need to consider the time, existing infrastructure, complexity, and cost of implementing your choice. The authentication method you choose, is configured by using Azure AD Connect, which also provisions users in the cloud. Choosing the correct authentication method is a crucial first decision in setting up an Azure AD hybrid identity solution. When the Azure AD hybrid identity solution is your new control plane, authentication is the foundation of cloud access. Cloud-only identities exist solely in the cloud and aren't associated with corresponding on-premises identities. Typically, those businesses create identities only in the cloud, which doesn't require a hybrid identity solution. Organizations that don't have an existing on-premises directory footprint aren't the focus of this article. Staged rollout is a great way to test users' migration from federation to cloud authentication. Changing your authentication method requires planning, testing, and potentially downtime.
