Implementing Passwordless Authentication with FIDO2
Overview
Deploy FIDO2/WebAuthn passwordless authentication using security keys and platform authenticators. Covers WebAuthn API integration, FIDO2 server configuration, passkey enrollment, biometric authentication, and migration from password-based systems aligned with NIST SP 800-63B AAL3.
When to Use
- When deploying or configuring implementing passwordless authentication with fido2 capabilities in your environment
- When establishing security controls aligned to compliance requirements
- When building or improving security architecture for this domain
- When conducting security assessments that require this implementation
Prerequisites
- Familiarity with identity access management concepts and tools
- Access to a test or lab environment for safe execution
- Python 3.8+ with required dependencies installed
- Appropriate authorization for any testing activities
Objectives
- Implement comprehensive implementing passwordless authentication with fido2 capability
- Establish automated discovery and monitoring processes
- Integrate with enterprise IAM and security tools
- Generate compliance-ready documentation and reports
- Align with NIST 800-53 access control requirements
