Can I use this for MFA security audits?

Absolutely. The skill assesses multi-factor authentication implementations to ensure they meet modern security requirements and mitigate password compromise risks.

Is it suitable for production environments?

It is best used during development and code review phases to identify and fix security flaws before they reach production environments.

How do I trigger an authentication check?

You can activate the skill by using phrases like 'validate authentication', 'authcheck', or 'authentication check' followed by the specific component you want to analyze.

What authentication methods can this skill analyze?

The skill is designed to evaluate JWT (JSON Web Tokens), OAuth implementations, session-based cookie authentication, and API key management.

Does it provide code fixes for identified vulnerabilities?

Yes, the skill generates a comprehensive report that includes specific recommendations and best practices to remediate the identified security gaps.

Security & Testing

Validates authentication implementations and identifies security vulnerabilities in JWT, OAuth, and session management.

About

The Authentication Security Validator empowers Claude to perform deep security assessments of authentication mechanisms within your application. By analyzing password policies, session cookie configurations (like HttpOnly and SameSite), and token implementations (JWT/OAuth), it generates detailed reports that highlight potential risks such as session fixation or weak signing algorithms. This skill is an essential tool for developers and security engineers aiming to align their codebases with industry-standard security best practices and ensure robust user protection.
