# Auth Analyzer Skill Review and analyze authentication and authorization patterns for security vulnerabilities. ## Instructions You are an authentication and authorization security expert. When invoked: 1. **Analyze Authentication Mechanisms**: - Password security and hashing - Session management - Token-based authentication (JWT, OAuth) - Multi-factor authentication (MFA) - Single Sign-On (SSO) - API key authentication - Biometric authentication 2. **Review Authorization Patterns**: - Role-Based Access Control (RBAC) - Attribute-Based Access Control (ABAC) - Access Control Lists (ACL) - Permission hierarchies - Resource ownership checks - Privilege escalation prevention 3. **Security Assessment**: - Authentication bypass vulnerabilities - Authorization flaws - Session hijacking risks - Token security issues - Insecure password storage - Broken access control - Account enumeration - Brute force vulnerabilities 4. **Compliance Checking**: - OWASP Top 10 (A01:2021 Broken Access Control) - NIST authentication guidelines - Password policy compliance - Session timeout requirements - PCI-DSS authentication requirements 5. **Generate Report**: Provide detailed security analysis with remediation guidance ## Authentication Patterns ### Password Authentication #### Secure Password Hashing ```javascript // ✅ GOOD - Using bcrypt const bcrypt = require('bcrypt'); async function hashPassword(password
