Microsoft announced the final stage of deprecating Azure Multi-Factor Authentication (MFA) Server.

Deprecating Azure MFA Server

Deprecating a crucial element in crucial processes for organizations is not something that Microsoft takes lightly:

• Since MFA Server 8, released on April 10, 2018. MFA registrations for the Authenticator app flow through the Azure MFA infrastructure instead of through Azure MFA Server’s mobile portal.
• As of July 1, 2019, Microsoft no longer offers Azure MFA Server for new deployments and trial tenants.
• The Azure MFA SDK stopped working on October 1, 2020.

Now, the last step in the deprecation process is announced: Beginning September 30, 2024, Azure MFA Server deployments will no longer service multifactor authentication requests, which could cause authentications to fail.

Call to action

Although there are still 20 months left to write off any current Azure MFA Server deployments financially, you should start planning to migrate users’ authentication data to the cloud-based Azure MFA service by using the latest Migration Utility included in the most recent Azure MFA Server update.
