 > [!IMPORTANT]
-> As of July 1, 2019, Microsoft no longer offers MFA Server for new deployments. New customers that want to require multi-factor authentication (MFA) during sign-in events should use cloud-based Azure AD Multi-Factor Authentication.
+> In September 2022, Microsoft announced deprecation of Azure Multi-Factor Authentication Server. Beginning September 30, 2024, Azure Multi-Factor Authentication Server deployments will no longer service multifactor authentication (MFA) requests, which could cause authentications to fail for your organization. To ensure uninterrupted authentication services and to remain in a supported state, organizations should [migrate their users’ authentication data](how-to-migrate-mfa-server-to-azure-mfa-user-authentication.md) to the cloud-based Azure MFA service by using the latest Migration Utility included in the most recent [Azure MFA Server update](https://www.microsoft.com/download/details.aspx?id=55849). For more information, see [Azure MFA Server Migration](how-to-migrate-mfa-server-to-azure-mfa.md).
