Previously, people had to set up an alternate MFA method like SMS or Voice before they could add a passkey (FIDO2), Windows Hello for Business, macOS Platform   SSO. That extra step pushed users toward weaker methods and slowed the move to phishing-resistant sign-in. Now password-only users can go straight to a passkey, making it easier to adopt strong authentication from day one. As part of this work, we will also   be enabling Authenticator App passwordless sign-in to be a user&#8217;s first registered MFA method.&nbsp;<\/p>\n<p><b>[Rollout schedule]<\/b><b><br \/>  <\/b><\/p>\n<p>This feature will roll out in phases:&nbsp;<\/p>\n<p>Phase 1: Support for synced passkeys, Microsoft Entra passkeys on Windows, and FIDO2 security keys.&nbsp;&nbsp;<\/p>\n<p>General Availability (Worldwide, GCC): We will begin rolling out in mid-October 2026 and expect to complete by mid-November 2026.&nbsp;<\/p>\n<p>Phase 2: Support for Windows Hello for Business, macOS Platform SSO, and Authenticator App passwordless sign-in.&nbsp;<\/p>\n<p>General Availability (Worldwide, GCC): We will begin rolling out in early January 2026 and expect to complete by late February 2027.&nbsp;<\/p>\n<p><b>[Impact on your organization]<\/b><\/p>\n<p><i>Who is affected<\/i><\/p>\n<ul>\n<li>Users who have not yet registered a multifactor authentication method<\/li>\n<li>Identity and security administrators responsible for authentication onboarding and registration policies<\/li>\n<\/ul>\n<p><i>Platforms and services<\/i><\/p>\n<ul>\n<li>Microsoft Entra ID<\/li>\n<li>Passkeys (FIDO2)<\/li>\n<li>Windows Hello for Business<\/li>\n<li>macOS Platform SSO<\/li>\n<li>Microsoft Authenticator passwordless sign-in<\/li>\n<\/ul>\n<p><i>What will happen<\/i><\/p>\n<ul>\n<li>Password-only users will be able to register passkeys or passwordless sign-in as their first MFA method.<\/li>\n<li>Users will no longer need to register a method such as SMS or voice before registering a passkey (FIDO2), Windows Hello for Business, macOS Platform SSO, or Authenticator passwordless sign-in.<\/li>\n<li>Organizations may see reduced registration friction and increased adoption of phishing-resistant authentication methods.<\/li>\n<\/ul>\n<p><b>[Action required and recommendations]<\/b><\/p>\n<p>No action is required for this change.<\/p>\n<p>We recommend that administrators:<\/p>\n<ul>\n<li>Review Conditional Access policies related to security information registration.<\/li>\n<li>Consider requiring MFA to register security information if additional verification is required by your organization.<\/li>\n<li>Review onboarding and registration guidance so users know to set up a passkey as their preferred first method.<\/li>\n<\/ul>\n<p>Learn more&nbsp;<\/p>\n<ul>\n<li>(To be updated closer to rollout)&nbsp;<a href=\"https:\/\/learn.microsoft.com\/entra\/identity\/authentication\/how-to-register-passkey\" target=\"_blank\">Register a synced passkey (FIDO2) | Authentication | Microsoft Entra ID | Microsoft Learn<\/a><\/li>\n<\/ul>\n<p><b>[Compliance considerations]<\/b><\/p>\n<table class=\"table table-bordered\">\n<tbody>\n<tr>\n<td>Question<\/td>\n<td>Answer<\/td>\n<\/tr>\n<tr>\n<td>Does the change include an admin control?<\/td>\n<td>Yes.
