Implements passwordless authentication using Microsoft Entra ID with FIDO2 security keys, Windows Hello for Business, Microsoft Authenticator passkeys, and certificate-based authentication to eliminate password-based attacks. Use when deploying passwordless sign-in, configuring FIDO2 passkeys, enforcing phishing-resistant MFA, or setting Microsoft Entra authentication method policies.

# 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.
