SKILL.md
This skill guides implementation of secure authentication systems with persistent session management, token-based authentication, and comprehensive user identity handling.
The user provides authentication requirements: login, registration, session management, or user profile features. They may include context about security needs, user experience expectations, or integration requirements.
Authentication System Principles
Before implementing, understand the security context and user experience requirements:
- Security First: What data needs protection? What are the threat vectors?
- User Experience: Balance security with friction - seamless for legitimate users, secure against attacks
- Session Management: How long should sessions last? When should re-authentication be required?
- Scalability: How will authentication scale with user growth?
- Compliance: What regulatory requirements apply (GDPR, data protection, etc.)?
CRITICAL: Authentication is a security-critical component. Every decision must prioritize user data protection while maintaining a smooth user experience.
