What problem does it solve?

Building secure, scalable authentication for Next.js apps is complex and error-prone. This Skill provides a production-ready Better Auth integration with robust session management, secure cookie handling, and deployment-focused hardening to reduce risk and speed up secure deployments.

Core Features & Use Cases

• Production-ready authentication for Next.js applications using the Better Auth MCP server.
• Secure session management with encrypted tokens, strict cookie attributes, and trusted origins across development and deployment environments.
• Supports server-side validation, middleware, and API routes to protect sensitive pages and data.
• Use Case: Deploy a secure admin dashboard with multi-environment configs (development, staging, production) while maintaining consistent security policies.

Quick Start

Configure environment variables (BETTER_AUTH_SECRET, BETTER_AUTH_URL, DATABASE_URL), install and integrate the Better Auth MCP in your Next.js app, and run with production-ready settings.
