# 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.

## 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

## Security Controls
| Control | NIST 800-53 | Description |
|---------|-------------|-------------|
| Account Management | AC-2 | Lifecycle management |
| Access Enforcement | AC-3 | Policy-based access control |
| Least Privilege | AC-6 | Minimum necessary permissions |
| Audit Logging | AU-3 | Authentication and access events |
| Identification | IA-2 | User and service identification |

## Verification
- [ ] Implementation tested in non-production environment
- [ ] Security policies configured and enforced
- [ ] Audit logging enabled and forwarding to SIEM
- [ ] Documentation and runbooks complete
- [ ] Compliance evidence generated
