SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Detects authentication vulnerabilities including weak password policies, missing brute force protection, insecure password storage, authentication bypass, hardcoded credentials, insecure password reset flows, and missing multi-factor authentication. Covers session-based, JWT, OAuth, and API key authentication models.

Core Features & Use Cases

  • Scans web applications and APIs for common authentication weaknesses such as weak hashing, missing brute force protections, insecure token handling, and exposed credentials.
  • Provides actionable remediation guidance and risk mitigation steps across languages and frameworks.
  • Use cases include pre-release code audits, security assessments of web services, and continuous CI checks to prevent credential-related breaches.

Quick Start

Instruct the AI to scan a codebase for authentication flaws and return a prioritized remediation plan.

Frequently Asked Questions about sc-auth

FAQPage Schema
How do I scan a codebase for authentication vulnerabilities like weak hashing and hardcoded credentials?

Detect authentication vulnerabilities by analyzing code and configuration patterns for weak hashing, hardcoded credentials, insecure password reset flows, and missing MFA across session-based, JWT, OAuth, and API key models, receiving actionable remediation guidance.

What is an authentication bypass vector and how does code review identify it?

An authentication bypass vector is a flaw allowing unauthorized access without valid credentials. Code review identifies bypass vectors by analyzing application logic and API configurations for insecure token handling, missing brute force protections, and weak session or JWT implementations.

Can I detect missing brute force protection and insecure JWT handling in APIs?

Yes, you can detect missing brute force protection and insecure JWT handling in APIs by scanning API code and configurations. The analysis targets gaps in rate limiting, insecure token validation, and exposed credentials across web apps and API endpoints.

Does this authentication vulnerability scanner work with OAuth and API key models?

Yes, this authentication vulnerability scanner works with OAuth and API key models, alongside session-based and JWT authentication. It analyzes code and config patterns to identify insecure token handling, hardcoded credentials, and missing MFA across these authentication frameworks.

How do I audit web application code for insecure password reset flows?

Audit web application code for insecure password reset flows by scanning the codebase for vulnerable patterns in the reset logic. The analysis detects weaknesses in reset token handling and validation, providing actionable remediation guidance to secure the flow.

What is the best way to integrate authentication security checks into a CI pipeline?

The best way to integrate authentication security checks into a CI pipeline is to automate codebase scanning for credential-related breaches. Continuous CI checks scan for weak password policies, hardcoded credentials, and authentication bypass vectors, returning a prioritized remediation plan.
