What this skill does

This skill enables Claude to validate authentication implementations against security best practices and industry standards. It analyzes various authentication methods, including JWT, OAuth, session-based authentication, and API keys. Use this skill when you need to perform an authentication security check, assess password policies, evaluate MFA implementation, or analyze session security. Trigger this skill with phrases like "validate authentication," "authentication check," or "authcheck.

Trigger phrases

Claude loads this skill automatically when you say things like:

“validate authentication,”“authentication check,”“authcheck.”

How it works

  1. Analyze Authentication Methods: The plugin examines the implemented authentication methods, such as JWT, OAuth, session-based, or API keys.
  2. Generate Security Report: The plugin generates a comprehensive report outlining potential vulnerabilities and recommended fixes related to password security, session management, token security (JWT), multi-factor authentication, and account security.

When to use it

  • Assess the security of an application's authentication implementation.
  • Identify vulnerabilities in password policies and session management.
  • Evaluate the security of JWT tokens and MFA implementation.
  • Ensure compliance with security best practices and industry standards.

Best practices

  • Token Expiration: Implement short-lived access tokens and refresh token rotation for enhanced security.
  • Multi-Factor Authentication: Encourage or enforce MFA to mitigate the risk of password compromise.
