Day in brief
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.

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.
