Signature Counter (Anti-Cloning) + +Spring Security's `JdbcUserCredentialRepository` automatically updates `signature_count` after each successful authentication. + +**How it works:** +- Counter must always increase +- If counter decreases, authenticator may be cloned +- Spring Security rejects authentication if counter doesn't increase + +**Verification:** +```sql +-- Check signature counter updates +SELECT credential_id, signature_count, last_used +FROM webauthn_user_credential +WHERE user_entity_id = ? +ORDER BY last_used DESC; +``` + +### 3. Challenge Management + +Spring Security handles: +- ✅ Cryptographically secure random challenges (32+ bytes) +- ✅ Challenge timeout (default 5 minutes) +- ✅ One-time use (prevents replay attacks) +- ✅ Stored in HTTP session by default + +**For stateless applications:** +Implement custom `PublicKeyCredentialCreationOptionsRepository` for distributed challenge storage (Redis, database). + +### 4. CSRF Protection + +**REQUIRED:** Keep CSRF protection enabled for WebAuthn endpoints. + +```java +// All WebAuthn endpoints require CSRF token +http.csrf(csrf -> csrf.disable()); // DON'T DO THIS! +``` + +Include CSRF token in all POST requests: +```javascript +headers: { + 'X-CSRF-TOKEN': getCsrfToken() +} +``` + +### 5. Account Lockout Prevention + +Implemented in `WebAuthnCredentialManagementService`: + +```java +// Prevent deletion of last passkey if user has no password +if (enabledCount == 1 && user.getPassword() == null) { + throw new WebAuthnException("Cannot delete last passkey"); +} +``` + +**Best Practices:** +- Encourage users to register multiple passkeys on different devices +- Maintain password as backup authentication method +- Provide account recovery mechanism (email reset) + +### 6. Origin Validation + +Configure `allowedOrigins` correctly: + +```properties +# Must match your application's origin exactly +user.webauthn.allowedOrigins=https://example.com,https://www.example.com +``` + +**Browser enforces:** +- RP ID must match domain +- Origin must be in allowedOrigins +- HTTPS required (except localhost) + +### 7. Pre-Authentication Requirement + +**Current Limitation:** Users must be authenticated before registering passkeys. + +**Security implications:** +- ✅ Prevents unauthorized passkey registration +- ✅ Ensures user identity before credential binding +- ❌ Cannot use for initial registration (passwordless onboarding) + +**Mitigation:** Document clearly that passkeys are an *enhancement* to existing authentication. + +--- + +## Spring Boot 4.0 Migration Path + +When migrating to Spring Boot 4.0 in the future, the changes are minimal. + +### Required Changes + +1. **Jackson 2 → Jackson 3** (Package imports) +2. **Test Configuration** (Add `@AutoConfigureMockMvc`) +3. **Null-Safety** (Optional - Add JSpecify annotations) + +### What Stays the Same + +- ✅ WebAuthn configuration (`.webAuthn()` DSL) +- ✅ Repository implementations (JDBC repositories) +- ✅ Database schema +- ✅ Service layer +- ✅ Frontend JavaScript +- ✅ API endpoints +- ✅ Overall architecture + +**Estimated Migration Time:** 1-2 weeks + +See [PASSKEY-SPRINGBOOT4-MIGRATION.md](PASSKEY-SPRINGBOOT4-MIGRATION.md) for detailed migration guide. + +--- + +## Future Enhancements + +### Phase 2 Features (Post-MVP) + +1. **Conditional UI (Autofill Passkeys)** + - Show passkeys in browser autofill + - Streamlined UX for returning users + - Requires WebAuthn Level 3 support + +2. **Passwordless Registration** + - Allow new user registration with passkey only + - Requires Spring Security enhancement or custom implementation + - Higher development effort + +3. **Advanced Analytics** + - Passkey adoption metrics dashboard + - Authentication success rates by authenticator type + - Geographic distribution of passkey usage + - Device distribution analysis + +4. **Account Recovery** + - Passkey-based account recovery mechanism + - Trusted device management + - Social recovery (trusted contacts) + +5. **Admin Dashboard** + - View users with passkeys + - Revoke credentials remotely + - Audit passkey usage + - Compliance reporting + +6. **Mobile App Integration** + - Native iOS/Android passkey support + - Cross-device authentication (QR code flow) + - Platform-specific optimizations + +7. **Enterprise Features** + - Attestation verification + - FIDO Metadata Service integration + - Authenticator allowlist/blocklist + - Enterprise attestation support + +--- + +## References + +### Official Documentation +- [Spring Security Passkeys Documentation](https://docs.spring.io/spring-security/reference/servlet/authentication/passkeys.html) +- [Spring Security 6.4 Release Notes](https://spring.io/blog/2024/11/19/spring-security-6-4-goes-ga/) +- [WebAuthn4J Spring Security Reference](https://webauthn4j.github.io/webauthn4j-spring-security/en/) +- [W3C WebAuthn Specification](https://www.w3.org/TR/webauthn-3/) +- [FIDO Alliance](https://fidoalliance.org/) + +### Tutorials & Guides +- [Baeldung: Integrating Passkeys into Spring Security](https://www.baeldung.com/spring-security-integrate-passkeys) +- [devgem.io: Implementing Passkey Registration with Spring Security](https://www.devgem.io/posts/implementing-passkey-registration-and-authentication-with-spring-security-and-webauthn4j) +- [WebAuthn.io Demo](https://webauthn.io/) +- [Auth0: WebAuthn and Passkeys for Java Developers](https://auth0.com/blog/webauthn-and-passkeys-for-java-developers/) + +### Browser Support +- [Can I Use: WebAuthn](https://caniuse.com/webauthn) +- Chrome 67+ (Windows, macOS, Android) +- Safari 13+ (macOS), 14+ (iOS) +- Firefox 60+ (Windows, macOS, Linux) +- Edge 18+ (Windows) + +--- + +## Document Revision History + +| Version | Date | Author | Changes | +|---------|------|--------|---------| +| 1.0 | 2025-11-30 | Initial | First draft with Yubico approach | +| 2.0 | 2025-11-30 | Revision | Switched to Spring Security native | +| 2.1 | 2025-11-30 | Corrected | Fixed critical issues from review | + +### Changes in Version 2.1 + +- ✅ Added `webauthn4j-core:0.29.7.RELEASE` dependency (CRITICAL) +- ✅ Fixed authentication endpoint: `/webauthn/authenticate` → `/login/webauthn` +- ✅ Fixed registration endpoint path: added `/webauthn/register/options` +- ✅ Added "Critical Requirements & Limitations" section +- ✅ Documented pre-authentication requirement prominently +- ✅ Added anonymousUser null checks in repository +- ✅ Documented signature counter behavior +- ✅ Updated to hybrid repository approach (built-in + custom) +- ✅ Fixed version consistency to Spring Boot 3.5.7 +- ✅ Enhanced frontend JavaScript with correct endpoint paths +- ✅ Added CSRF token handling throughout +- ✅ Improved error handling and edge cases + +--- + +## Conclusion + +This implementation plan leverages **Spring Security 6.5's native WebAuthn support**, providing: + +- ✅ **Production-ready** JDBC persistence +- ✅ **Official Spring Security** support and maintenance +- ✅ **Simpler architecture** without custom filters +- ✅ **Faster implementation** (6-7 weeks) +- ✅ **Future-proof** for Spring Boot 4.0 migration + +**Key Limitation:** Pre-authentication required for registration.

This eliminates the need for: -- ❌ Custom authentication filters -- ❌ Third-party library integration (Yubico) -- ❌ Manual challenge management -- ❌ Complex credential repository implementations - -Instead, you get: -- ✅ `.webAuthn()` DSL configuration -- ✅ Default endpoints (`/webauthn/register/*`, `/login/webauthn`) -- ✅ `UserCredentialRepository` interface for database integration -- ✅ Automatic session management -- ✅ Built-in security best practices - ---- - -## Critical Requirements & Limitations - -### ⚠️ Pre-Authentication Required for Registration - -**IMPORTANT:** Spring Security WebAuthn requires users to be **already authenticated** before they can register a passkey. This is a fundamental limitation of the current implementation. - -**Impact on User Flow:** - -``` -❌ CANNOT DO: -New User → Register Account with Passkey → Account Created - -✅ MUST DO: -New User → Register with Password/OAuth2 → Login → Add Passkey → Logout → Login with Passkey -``` - -**Workarounds:** - -1. **Option A:** Require password during registration, allow passkey addition after login -2. **Option B:** Use OAuth2/SSO for initial registration, add passkey after -3. **Option C:** Accept the limitation - passkeys as a "second factor" enhancement - -**Recommendation:** Implement Option A initially. Document clearly that passkey is an *enhancement* to existing authentication, not a replacement for initial registration. - -### ✅ HTTPS Requirement - -**WebAuthn requires HTTPS.** Browsers enforce this (except for localhost in development). - -**Development:** -- Use `https://localhost:8443` with self-signed certificate -- Generate with: `keytool -genkeypair -alias localhost -keyalg RSA -keysize 2048 -storetype PKCS12 -keystore keystore.p12 -validity 3650` - -**Production:** -- Use proper SSL certificate (Let's Encrypt, commercial CA) -- Configure TLS 1.2+ with strong ciphers -- Enable HSTS headers - -### ✅ Browser Compatibility - -| Browser | Version | Support | -|---------|---------|---------| -| Chrome/Edge | 67+ | ✅ Full | -| Safari (macOS) | 13+ | ✅ Full | -| Safari (iOS) | 14+ | ✅ Full | -| Firefox | 60+ | ✅ Full | - ---- - -## Spring Security Native WebAuthn Overview - -### How Spring Security WebAuthn Works - -Spring Security 6.5 provides first-class WebAuthn support through a simple configuration API: - -```java -@Bean -public SecurityFilterChain securityFilterChain(HttpSecurity http) throws Exception { - http - .webAuthn(webAuthn -> webAuthn - .rpName("Spring User Framework") - .rpId("example.com") - .allowedOrigins("https://example.com") - );

HTTPS Requirement (CRITICAL) - -**WebAuthn requires HTTPS.** Browsers enforce this (except for localhost in development). - -**Development:** -```bash -# Generate self-signed certificate -keytool -genkeypair -alias localhost -keyalg RSA -keysize 2048 \ - -storetype PKCS12 -keystore keystore.p12 -validity 3650 \ - -dname "CN=localhost" -storepass changeit -``` - -**Production:** -- Use Let's Encrypt or commercial SSL certificate -- Configure TLS 1.2+ with strong ciphers -- Enable HSTS headers: `Strict-Transport-Security: max-age=31536000; includeSubDomains` -- Implement Certificate Pinning (optional) - -### 2. Signature Counter (Anti-Cloning) - -Spring Security's `JdbcUserCredentialRepository` automatically updates `signature_count` after each successful authentication. - -**How it works:** -- Counter must always increase -- If counter decreases, authenticator may be cloned -- Spring Security rejects authentication if counter doesn't increase - -**Verification:** -```sql --- Check signature counter updates -SELECT credential_id, signature_count, last_used -FROM webauthn_user_credential -WHERE user_entity_id = ? -ORDER BY last_used DESC; -``` - -### 3. Challenge Management - -Spring Security handles: -- ✅ Cryptographically secure random challenges (32+ bytes) -- ✅ Challenge timeout (default 5 minutes) -- ✅ One-time use (prevents replay attacks) -- ✅ Stored in HTTP session by default - -**For stateless applications:** -Implement custom `PublicKeyCredentialCreationOptionsRepository` for distributed challenge storage (Redis, database). - -### 4. CSRF Protection - -**REQUIRED:** Keep CSRF protection enabled for WebAuthn endpoints. - -```java -// All WebAuthn endpoints require CSRF token -http.csrf(csrf -> csrf.disable()); // DON'T DO THIS! -``` - -Include CSRF token in all POST requests: -```javascript -headers: { - 'X-CSRF-TOKEN': getCsrfToken() -} -``` - -### 5. Account Lockout Prevention - -Implemented in `WebAuthnCredentialManagementService`: - -```java -// Prevent deletion of last passkey if user has no password -if (enabledCount == 1 && user.getPassword() == null) { - throw new WebAuthnException("Cannot delete last passkey"); -} -``` - -**Best Practices:** -- Encourage users to register multiple passkeys on different devices -- Maintain password as backup authentication method -- Provide account recovery mechanism (email reset) - -### 6. Origin Validation - -Configure `allowedOrigins` correctly: - -```properties -# Must match your application's origin exactly -user.webauthn.allowedOrigins=https://example.com,https://www.example.com -``` - -**Browser enforces:** -- RP ID must match domain -- Origin must be in allowedOrigins -- HTTPS required (except localhost) - -### 7. Pre-Authentication Requirement - -**Current Limitation:** Users must be authenticated before registering passkeys. - -**Security implications:** -- ✅ Prevents unauthorized passkey registration -- ✅ Ensures user identity before credential binding -- ❌ Cannot use for initial registration (passwordless onboarding) - -**Mitigation:** Document clearly that passkeys are an *enhancement* to existing authentication. - ---- - -## Spring Boot 4.0 Migration Path - -When migrating to Spring Boot 4.0 in the future, the changes are minimal. - -### Required Changes - -1. **Jackson 2 → Jackson 3** (Package imports) -2. **Test Configuration** (Add `@AutoConfigureMockMvc`) -3. **Null-Safety** (Optional - Add JSpecify annotations) - -### What Stays the Same - -- ✅ WebAuthn configuration (`.webAuthn()` DSL) -- ✅ Repository implementations (JDBC repositories) -- ✅ Database schema -- ✅ Service layer -- ✅ Frontend JavaScript -- ✅ API endpoints -- ✅ Overall architecture - -**Estimated Migration Time:** 1-2 weeks - -See [PASSKEY-SPRINGBOOT4-MIGRATION.md](PASSKEY-SPRINGBOOT4-MIGRATION.md) for detailed migration guide. - ---- - -## Future Enhancements - -### Phase 2 Features (Post-MVP) - -1. **Conditional UI (Autofill Passkeys)** - - Show passkeys in browser autofill - - Streamlined UX for returning users - - Requires WebAuthn Level 3 support - -2. **Passwordless Registration** - - Allow new user registration with passkey only - - Requires Spring Security enhancement or custom implementation - - Higher development effort - -3. **Advanced Analytics** - - Passkey adoption metrics dashboard - - Authentication success rates by authenticator type - - Geographic distribution of passkey usage - - Device distribution analysis - -4. **Account Recovery** - - Passkey-based account recovery mechanism - - Trusted device management - - Social recovery (trusted contacts) - -5. **Admin Dashboard** - - View users with passkeys - - Revoke credentials remotely - - Audit passkey usage - - Compliance reporting - -6. **Mobile App Integration** - - Native iOS/Android passkey support -
