Auth Security Review

Review and improve authentication/authorization:

1. Audit authentication logic:

   • Password hashing (use bcrypt/argon2)
   • Session management
   • Token generation and validation

2. Review authorization:

   • Role-based access control (RBAC)
   • Permission checks
   • Resource ownership validation

3. Implement improvements:

   • Add multi-factor authentication support
   • Implement secure session invalidation
   • Add brute force protection
   • Improve token expiration handling

Success Criteria

• Strong password hashing algorithm in use
• Secure session management implemented
• RBAC properly enforced on all protected resources
• Brute force protection active
• Token expiration and refresh working correctly

Completion Checklist

• Audit all authentication endpoints
• Create tests for auth flows and edge cases
• Document authentication architecture
• Test authorization on all protected resources
• Verify session timeout and renewal
