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.
