Better Auth Best Practices

What it does

This skill provides a curated set of security best practices specifically designed to harden authentication implementations using the Better-Auth library. It ensures AI agents can configure secure login flows, manage session lifecycles, and enforce robust access controls without manual research into complex security patterns.

When to use it

• You are initializing a new project and need to set up a production-ready authentication system from the ground up.
• Your application requires strict compliance with modern security standards for user data protection and session management.
• You need to implement specific security features like email verification, password policies, or multi-factor authentication quickly.
• You are auditing an existing Better-Auth setup to ensure it aligns with industry-standard security recommendations.

Key capabilities

• Configures secure default settings for user registration and login processes.
• Enforces strong password policies and input validation rules.
• Manages session tokens, expiration times, and refresh mechanisms securely.
• Implements protection against common vulnerabilities like brute-force attacks and token leakage.

Example prompts

• "Configure Better-Auth with industry-standard security defaults for a new SaaS application."
• "Set up email verification and password reset flows using the best-practices skill."
• "Audit my current authentication configuration against Novu's recommended security guidelines."

Tips & gotchas

Ensure your backend environment variables are properly configured before applying these practices, as many security features rely on specific secret keys being present. While this skill covers standard patterns, always review the generated code for custom business logic that might introduce new attack vectors.
