Microsoft will introduce passkey support for phishing-resistant passwordless authentication on Microsoft Entra-protected resources starting in late April, with broader availability expected by mid-June 2026. This feature will allow passwordless sign-in on unmanaged Windows devices and will support various device types, including corporate, personal, and shared options. Administrators can manage passkeys through Conditional Access and Authentication Methods policies. Users can create device-bound passkeys stored securely within the Windows Hello container, using methods like facial recognition, fingerprint scanning, or a PIN. The passkeys will adhere to FIDO2 standards and will be securely bound to individual devices, preventing transmission over the network to enhance security against phishing and malware attacks. Microsoft has also announced plans for mandatory multifactor authentication registration for Entra tenants by October 2024 and that all new accounts will be passwordless by default starting in May 2025.
