Can it help with password security?

Yes, it evaluates password policies and hashing implementations (like bcrypt or Argon2) to ensure they follow security best practices.

Which authentication methods does this skill support?

It supports a wide range of methods including JSON Web Tokens (JWT), OAuth protocols, session-based authentication, and API key management.

Does it provide remediation steps?

Absolutely. After identifying a vulnerability, the skill generates a report with specific recommendations and code-level fixes to improve security.

Is it useful for compliance audits?

Yes, it helps developers align their authentication logic with industry standards, making it significantly easier to meet security compliance requirements.

How do I trigger the authentication validator?

You can activate the skill by using phrases like 'validate authentication,' 'authcheck,' or 'authentication security check' within Claude Code.
