About this tag
The mfa migration tag covers Microsoft Entra ID changes affecting SMS and voice-based multifactor authentication, including the February 1, 2027 retirement deadline for Microsoft-operated delivery in the public cloud. Tagged discussions focus on planning the transition, identifying users who rely solely on phone-based codes or calls, and avoiding sign-in disruptions when passkey registration becomes required.
