Entra ID will make passkeys the default and retire Microsoft-provided SMS and voice authentication

17 July was a quiet Entra ID period, with one consequential Message Center announcement and one low-impact documentation update. The major update describes a future authentication behavior change: passkeys become the default on 1 September 2026, while Microsoft-provided SMS and voice authentication retire by 1 February 2027. The Linux Device Registration Tool item provides no evidence of changed product behavior.

  Passkeys become the default authentication method, with Microsoft-provided SMS and voice authentication retiring

  A Microsoft 365 Message Center major update announces a planned Entra ID authentication change, not a launch occurring on this date. Passkeys will be the default authentication method starting 1 September 2026, and Microsoft-provided SMS and voice authentication will be retired by 1 February 2027. Customers must configure telecom providers for SMS and voice through the Microsoft Security Store to avoid disruption. The notice describes passkeys as phishing-resistant and available at no extra cost.

  Linux Device Registration Tool troubleshooting documentation was updated

  The Microsoft Learn page was marked as updated, but the supplied summary contains only a NOTE marker and no changed troubleshooting steps, tenant settings, security guidance, or rollout behavior. Treat this as an ordinary documentation clarification rather than evidence of a product change or required configuration action.
