Microsoft MyAccount: What Changed?

Key insights

• My Account now supports new passkey profiles and synced passkeys managed through Microsoft Entra ID.
  Public preview began in December 2025 and general availability completed by late February 2026.
• FIDO2-based passkeys use public-key cryptography to replace passwords.
  The new passkeyType property distinguishes device-bound keys from cloud-synced credentials for cross-device sign-in.
• Tenants that do not opt in will auto-migrate to a Default passkey profile to preserve existing FIDO2 keys.
  Admins can require attestation to limit registrations to hardware-bound keys if needed.
• Microsoft-managed registration campaigns now prioritize passkeys over SMS or voice, with gentler reminders (unlimited snoozes and daily nudges).
  Users enroll passkeys via apps like Microsoft Authenticator or browser prompts for simpler setup.
• Passkeys improve passwordless security and offer stronger phishing resistance.
  They also help avoid common login glitches after Windows updates by integrating with Windows Hello and cloud syncing.
• Action steps: check Entra ID tenant settings, plan the profile migration, and ask users to add passkeys at account.microsoft.com/security.
  Test sign-ins across devices to confirm seamless access.
