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
Compliance Framework Mapping
This skill supports compliance evidence collection across multiple frameworks:
- SOC 2: CC6.1 (Logical Access), CC6.2 (Credentials), CC6.3 (Provisioning)
- ISO 27001: A.9.1 (Access Control), A.9.2 (User Access Management), A.9.4 (System Access Control)
- NIST 800-53: AC-2 (Account Management), IA-2 (Identification), AC-6 (Least Privilege)
- NIST CSF: PR.AC (Access Control)
Claw GRC Tip: When this skill is executed by a registered agent, compliance evidence is automatically captured and mapped to the relevant controls in your active frameworks.
Deploying This Skill with Claw GRC
Agent Execution
Register this skill with your Claw GRC agent for automated execution:
# Install via CLI
npx claw-grc skills add implementing-passwordless-authentication-with-fido2
# Or load dynamically via MCP
grc.load_skill("implementing-passwordless-authentication-with-fido2")Audit Trail Integration
When executed through Claw GRC, every step of this skill generates tamper-evident audit records:
- SHA-256 chain hashing ensures no step can be modified after execution
- Evidence artifacts (configs, scan results, logs) are automatically attached to relevant controls
- Trust score impact — successful execution increases your agent's trust score
Continuous Compliance
Schedule this skill for recurring execution to maintain continuous compliance posture. Claw GRC monitors for drift and alerts when re-execution is needed.
