Attack Protection

Bot Detection: Navigate to Dashboard > Security > Attack Protection > Bot Detection. Configure sensitivity (Low/Medium/High) and response type (Auth Challenge recommended, Simple CAPTCHA, or third-party). IP AllowList supports up to 100 adddesses/CIDR ranges.

Supported flows: Universal Login, Classic Login, Lock.js v12.4.0+, native apps. Unsupported: Enterprise connections, social login, cross-origin authentication.

Breached Password Detection: Enable for signup and login. Response actions include blocking compromised credentials and user/admin notifications. Standard Detection has 7-13 months detection time; Credential Guard (Enterprise) reduces to 12-36 hours. Test with passwords starting with AUTH0-TEST-.

Brute Force Protection: Default threshold is 10 failed attempts (configurable 1-100). Protection mechanisms include IP-based blocking and account lockout. Blocks remove after 30 days, password change, admin removal, or user unblock link.

Suspicious IP Throttling: Velocity-based detection for high-volume attacks. Responds with HTTP 429. Configure separate thresholds for login (daily) and signup (per minute) attempts.

Multi-Factor Authentication

Factor Configuration: Navigate to Dashboard > Security > Multi-factor Auth.

Independent Factors (at least one required):

• WebAuthn with FIDO Security Keys
• One-time Password (OTP/TOTP)
• Push Notifications via Auth0 Guardian
• Phone Message (SMS/Voice)
• Cisco Duo Security

Dependent Factors: WebAuthn Biometrics, Email, Recovery codes

MFA Policies: Never, Use Adaptive MFA (Enterprise), Always

WebAuthn: Provides passwordless MFA with security keys or biometrics. Single interaction for multi-factor authentication, phishing-resistant.

Adaptive MFA (Enterprise): Evaluates risk signals per transaction:

• NewDevice: Device not used in past 30 days
• ImpossibleTravel: Geographic anomalies
• UntrustedIP: Suspicious activity history

High-risk transactions require verification regardless of existing MFA sessions.

Step-Up Authentication: Enhanced verification for sensitive operations. APIs use scopes; web apps verify ID token claims.

For details: modules/mfa-overview.md, modules/adaptive-mfa.md

Token Security

JWT Fundamentals: RFC 7519 standard. Auth0 issues signed JWTs (JWS). Structure includes Header, Payload (claims), and Signature. Always validate signatures, never store sensitive data in payloads, use HTTPS only.

Access Tokens: Authorize API access with scopes. Types: Opaque (require introspection) and JWT (self-contained). Key claims: iss, sub, aud, scope, exp. Default lifetime: 86400 seconds (24 hours).

Refresh Tokens: Enable session continuity. Maximum 200 active per user per application. Security features: Rotation (invalidates predecessor), expiring tokens (idle/absolute), revocation via Management API.

Best Practices:

• Treat signing keys as critical credentials
• Prefer RS256 over HS256 for public key validation
• Store tokens server-side when possible
• Cache and reuse until expiration

For details: modules/tokens-overview.md, modules/token-best-practices.md

Sender Constraining

DPoP (Application Layer): Binds tokens to client-generated asymmetric key pairs.

Steps: Generate key pair (ES256 recommended), create DPoP Proof JWT, send via DPoP header, include updated proof with each API request.

Proof JWT Structure:

• Header: typ (dpop+jwt), alg, jwk (public key)
• Payload: jti, htm, htu, iat, ath (for API calls)

Public clients must handle use_dpop_nonce errors.

mTLS (Transport Layer): Binds tokens to X.509 certificates.

Process: Client establishes mTLS connection, Auth0 calculates certificate SHA-256 thumbprint, embeds in token cnf claim as x5t#S256. Resource server validates thumbprint.

Requirements: Confidential clients only, Enterprise Plan with HRI add-on, PKI infrastructure.

For details: modules/dpop-implementation.md, modules/mtls-sender-constraining.md

Compliance

Highly Regulated Identity (Enterprise + HRI add-on):

• Strong Customer Authentication: Minimum two independent factors
• Dynamic Linking: Transaction details in authorization
• PAR: Pushed Authorization Requests
• JAR: JWT-Secured Authorization Requests
• JWE: Access token encryption
• Private Key JWT and mTLS authentication

GDPR Compliance:

• Customer as Data Controller, Auth0 as Data Processor
• User rights: Access, portability (JSON export), erasure, consent management
• Security: Profile encryption, breach detection, brute-force protection

Certifications: ISO 27001/27017/27018, SOC 2 Type 2, CSA STAR, FAPI 1 Advanced OP, HIPAA BAA available, PCI DSS compliant models

For details: modules/highly-regulated-identity.md, modules/gdpr-compliance.md

Security Center Monitoring

Access from Dashboard > Security > Security Center.

Threat Categories:

• Credential Stuffing: Machine-driven compromise attempts
• Signup Attacks: Automated account creation
• MFA Bypass: Circumvention attempts

Filtering: Time period (up to 14 days), applications, connections. Auto-aggregation by minute/hour/day.

Metrics: Bot detection counts, IP throttling events, brute force triggers, breached password alerts, MFA success/failure rates.

Application Credentials

Client Secret (Default): Symmetric, simple but vulnerable to interception.

Private Key JWT (Enterprise): Asymmetric key pairs, private key never transmitted, short-lived assertions. Recommended for enhanced security.

mTLS for OAuth (HRI): X.509 certificates, strongest protection.

Key Management: Register up to two public keys for zero-downtime rotation. Algorithms: RS256, RS384, PS256.

Continuous Session Protection

Use Auth0 Actions for session context during token refresh events.

Capabilities: IP/ASN monitoring, device tracking, expiration management, anomaly detection.

Dynamic management: Customize lifetimes by user attributes, organization, or role.
