Microsoft sets February 2027 SMS/voice SSPR retirement with 50-day transitions

The week’s most consequential change is Microsoft’s planned retirement of Microsoft-provided SMS and voice authentication for self-service password reset starting February 2027, with a 50-day transition for each user group. Microsoft Entra Private Access also introduced a sign-in-every-time preview requiring Conditional Access and Global Secure Access Windows client version 2.34.222 or later. Other meaningful updates added an end-to-end customer-owned telephony setup guide, documented a December 1, 2026 Salesforce provisioning requirement, and clarified an Entra SSH failure mode after RHEL upgrades. Much of the remaining activity involved documentation maintenance, links, and command examples.

  • Microsoft-provided SMS and voice authentication for self-service password reset will retire starting in February 2027. Each user group receives a 50-day transition, after which those methods will no longer be available for SSPR; organizations need alternative recovery methods.

  • The preview depends on Conditional Access, requires the Global Secure Access Windows client version 2.34.222 or later, and uses a five-minute reauthentication window. Administrators should verify client coverage and use device-platform exclusions for non-Windows users where needed.

  • The new end-to-end guide covers purchasing and activating a telecom provider, deploying the Azure integration, configuring authentication method profiles, validating evaluation mode, and gradually rolling out SMS and voice delivery. It also identifies the Azure resources, tools, permissions, and testing steps to review.

  • The Salesforce provisioning tutorial now requires SOAP API login() to be enabled and the Admin Username account to have Use Any API Auth. It also records Salesforce’s December 1, 2026 requirement; enabling the setting and granting the permission helps prevent credential-validation failures.

  • In-place upgrades from RHEL 8.x to 9.x can remove the aadsshlogin package and cause Permission denied (publickey) errors. If Entra SSH sign-in fails, the documented remedy is to uninstall and reinstall the AADSSHLoginForLinux extension.

For Entra administrators

Prepare alternative SSPR recovery methods and plan around the 50-day user-group transition. For Private Access, verify supported Windows clients and use device-platform exclusions where non-Windows users need different handling. Use the new Microsoft Entra admin center guide for customer-owned SMS and voice, grant Salesforce’s required permission before December 1, 2026, and check the AADSSHLoginForLinux extension if Entra SSH sign-in fails after an affected RHEL upgrade.
