SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) components.

What problem does it solve?

This Skill provides guidance, tools, and verification steps to deploy FIDO2/WebAuthn passwordless authentication, reducing reliance on passwords, preventing phishing and credential theft, and aligning authentication with NIST AAL3 requirements.

Core Features & Use Cases

Integration Guidance: Detailed WebAuthn API integration and server-side FIDO2 library usage for registration and authentication flows.
Deployment & Policy Checks: Configuration validation including attestation enforcement, AAGUID restrictions, and Azure AD FIDO2 policy auditing.
Operational Workflows: Enrollment, migration from passwords to passkeys, lost-key recovery, and adoption reporting using the included audit agent.
Use Case: Pilot FIDO2 for an enterprise web application to enroll passkeys for privileged users, enforce attestation and key restrictions, and measure adoption with automated reports.

FAQPage Schema

How do I deploy WebAuthn passwordless authentication for my web application?▼

To deploy WebAuthn passwordless authentication, you need to integrate the WebAuthn API on the client side and a server-side FIDO2 library like python-fido2 to handle registration and authentication flows, replacing your existing password-based login.

What is FIDO2 passkey enrollment and how does it prevent phishing?▼

FIDO2 passkey enrollment registers a public-key credential tied to your domain, preventing phishing by cryptographically ensuring authentication requests only succeed on the legitimate relying party's origin, eliminating shared secrets that attackers can steal.

Can I use this to migrate privileged users from passwords to passkeys in an enterprise IAM?▼

Yes, you can migrate privileged users from passwords to passkeys within an enterprise IAM by following structured operational workflows for enrollment, enforcing attestation and AAGUID restrictions, and monitoring adoption using automated audit reports.

How do I enforce attestation and AAGUID restrictions during FIDO2 registration?▼

You enforce attestation and AAGUID restrictions during FIDO2 registration by configuring your server-side relying party to validate the attestation statement and restrict authenticator models using AAGUID policies, ensuring only approved hardware is accepted.

Does FIDO2 passwordless authentication meet NIST AAL3 compliance requirements?▼

FIDO2 passwordless authentication aligns with NIST AAL3 requirements by utilizing phishing-resistant hardware-backed authenticators and attestation verification to provide strong identity assurance for high-security applications.

What is the best way to audit Azure AD FIDO2 policy and measure passkey adoption?▼

The best way to audit Azure AD FIDO2 policy and measure passkey adoption is to use an automated audit agent that validates configuration, verifies compliance, and generates adoption reports for your identity provider environment.
