Implementing Passwordless Auth with Microsoft Entra

When to Use

  • Organization wants to eliminate password-based attacks (phishing, credential stuffing, brute force)
  • Regulatory or internal mandate requires phishing-resistant MFA (Executive Order 14028, CISA guidance)
  • Deploying FIDO2 security keys or Windows Hello for Business across the enterprise
  • Migrating from legacy MFA (SMS, phone call) to phishing-resistant authentication methods
  • Implementing passkey support for hybrid or cloud-joined Windows devices
  • Reducing helpdesk costs from password reset requests

Do not use for environments that cannot support modern authentication protocols; legacy applications using NTLM or basic authentication must be migrated first.

Prerequisites

  • Microsoft Entra ID P1 or P2 license (Azure AD Premium)
  • Windows 10/11 22H2+ for Windows Hello for Business deployment
  • FIDO2-compliant security keys (YubiKey 5 Series, Feitian BioPass, Google Titan)
  • Microsoft Authenticator app 6.8+ for passkey support on iOS 16+/Android 14+
