The Passwordless Revolution
Passwords are the weakest link in authentication. Despite decades of policy enforcement, password-based attacks (phishing, credential stuffing, brute force) remain the #1 cause of breaches. Passwordless authentication eliminates this attack surface entirely.
Technologies
FIDO2/WebAuthn
The gold standard for passwordless authentication:- Platform authenticators: Biometrics built into devices (Touch ID, Windows Hello)
- Roaming authenticators: Hardware security keys (YubiKey, Titan)
- Cryptographic challenge-response (no shared secrets)
- Phishing-resistant by design (bound to origin)
Passkeys
Consumer-friendly implementation of FIDO2:- Synced across devices via iCloud Keychain, Google Password Manager
- No hardware key required
- Biometric unlock (fingerprint, face)
- Automatic, seamless user experience
Certificate-Based Authentication
For enterprise and machine-to-machine:- mTLS with client certificates
- Smart card authentication
- PIV/CAC compliance for government
Enterprise Deployment Strategy
Phase 1: Foundation
- Deploy FIDO2-compatible Identity Provider
- Inventory systems supporting WebAuthn
- Pilot with IT and security teams
Phase 2: Rollout
- Distribute hardware security keys to high-risk users
- Enable passkey registration for all employees
- Implement passwordless as preferred (not required) option
Phase 3: Enforcement
- Require passwordless for privileged access
- Remove password option for FIDO2-capable applications
- Maintain password fallback only for legacy systems
Phase 4: Optimization
- Remove remaining password dependencies
- Implement risk-based adaptive authentication
- Continuous improvement based on user feedback
Security Advantages
- Phishing-resistant: Cryptographic binding to origin prevents credential theft
- No shared secrets: Nothing stored server-side that can be breached
- No replay attacks: Challenge-response with unique nonces
- No credential stuffing: No passwords to reuse across sites
Where SuperClue Fits
SuperClue does not find password-dependent systems or plan a migration. Its DAST scanner checks the login pages and session cookies of the web applications you scan, and its IAM modules ask for evidence of your password and MFA policies.
