FAQPage Schema
How do I add TypeScript authentication with OAuth and JWT to my Next.js app?

TypeScript authentication with OAuth and JWT is configured using a plugin-based system and server/client templates. It supports Next.js, React, and Express out of the box, covering email/password, sessions, and magic links across your stack.

Can I use better-auth-ts with my existing Prisma or MongoDB database setup?

Yes, TypeScript authentication integrates directly with existing databases using ORM adapters for Prisma, Drizzle, Kysely, and MongoDB. These adapters support migration-friendly workflows to map your auth tables without rebuilding your data layer.

What is the best way to implement two-factor authentication in a TypeScript project?

Two-factor authentication in a TypeScript project is implemented through the framework's built-in 2FA plugin. It works alongside email/password, OAuth, and JWT sessions to provide a comprehensive and secure sign-in flow.

Does this TypeScript authentication toolkit support magic links and session management?

Yes, the TypeScript authentication toolkit fully supports magic links and session management. It handles secure token generation and validation alongside core email/password and OAuth flows.

How do I set up authentication across multiple frameworks like React and Express?

Authentication across React and Express uses provided server and client templates for multi-platform integrations. You install the package and apply the plugin-based configuration to share auth logic across frontend and backend TS projects.

Why should I use a plugin-based authentication system instead of building my own?

A plugin-based authentication system simplifies secure integration of complex sign-in flows like 2FA and OAuth across frontend and backend stacks. It prevents security gaps by providing robust, pre-built configurations for TypeScript apps.
