SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill streamlines the implementation of robust and secure authentication systems in TypeScript applications, addressing the complexities of user management, social logins, and multi-factor authentication.

Core Features & Use Cases

  • Secure Authentication: Implement email/password login with verification, and integrate social OAuth providers like Google and GitHub.
  • Enhanced Security: Add Two-Factor Authentication (2FA) and manage user sessions securely.
  • Use Case: When building a new Next.js application that requires user accounts, integrate this Skill to handle user sign-up, login, and secure session management, including options for social logins and MFA.

Quick Start

Use the Implementing Better Auth skill to set up email/password authentication with Google OAuth and session management in a Next.js application.

Frequently Asked Questions about Implementing Better Auth

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I implement authentication with email/password and Google OAuth in Next.js?▼

Authentication in Next.js can be implemented using TypeScript to handle email/password login alongside Google OAuth integration. This approach provides secure user management and social provider sign-in capabilities for your application.

What is the best way to manage user sessions securely in a TypeScript application?▼

Secure session management in TypeScript applications is best handled by storing session data in httpOnly cookies. This method prevents client-side scripts from accessing the tokens, ensuring robust session security for Next.js environments.

How do I add TOTP-based multi-factor authentication to an existing TypeScript app?▼

Adding TOTP-based multi-factor authentication involves integrating a 2FA mechanism on top of your existing email/password or OAuth flows. This enhances security by requiring a time-based one-time password during the user login process.

Does this authentication approach support social login providers other than Google and GitHub?▼

The authentication implementation specifically supports OAuth integration with Google and GitHub. While it establishes secure social login patterns, the current scope explicitly covers these two providers for TypeScript applications.

When do I need to use httpOnly cookies for session handling?▼

HttpOnly cookies are needed for session handling when you want to protect your application from cross-site scripting (XSS) attacks. They ensure that session tokens managed during user authentication cannot be accessed by client-side scripts.
