Better Auth Best Practices

What it does

This skill provides a curated collection of security best practices specifically designed for configuring and securing better-auth, a popular authentication library. It helps developers implement robust identity management, session handling, and protection against common vulnerabilities like CSRF and brute-force attacks.

When to use it

• Setting up production-ready authentication flows with industry-standard security configurations.
• Hardening existing better-auth instances to prevent credential stuffing or token hijacking.
• Integrating secure password policies and multi-factor authentication (MFA) strategies.
• Ensuring compliance with security guidelines when deploying applications handling sensitive user data.

Key capabilities

• Secure Configuration: Applies hardened defaults for the better-auth library to minimize attack surface.
• Session Management: Implements best practices for token generation, rotation, and expiration.
• Vulnerability Mitigation: Includes specific settings to guard against Cross-Site Request Forgery (CSRF) and other injection risks.
• Password Security: Enforces strong password requirements and hashing standards.

Example prompts

• "Configure better-auth with the security best practices outlined by connorads for a new user registration flow."
• "Apply hardened session management settings to my existing authentication provider using this skill."
• "Generate a secure initialization script for better-auth that includes CSRF protection and MFA support."

Tips & gotchas

Ensure your application environment supports the specific cryptographic standards required by these best practices before deployment. Regularly update the underlying better-auth library to maintain compatibility with evolving security threats, even when using these configurations.
