FAQPage Schema
How do I add OAuth and 2FA to my TypeScript web app?▼

To implement authentication in TypeScript, install `better-auth`, configure environment variables for secrets and URLs, then initialize the auth server and client. This supports email/password, OAuth, passkeys, and session management for web applications.

What is the best way to set up passkeys and magic links for TypeScript applications?▼

Setting up passkeys and magic links for TypeScript applications is handled by configuring authentication instances using `better-auth`. This framework provides passwordless login methods alongside traditional email and OAuth strategies for secure access.

Yes, better-auth works with Next.js, SvelteKit, Express, Nuxt, Remix, Astro, and Hono. The Skill supports multi-framework integration to implement secure sign-in and session management across various TypeScript web environments.

Why use better-auth for session management in TypeScript instead of building a custom solution?▼

Using better-auth for session management in TypeScript provides pre-built support for email, OAuth, 2FA, and passkeys without custom boilerplate. It simplifies securing web applications by managing complex authentication flows and session states natively.

How to configure environment variables for OAuth providers in a TypeScript auth setup?▼

To configure environment variables for OAuth providers in a TypeScript auth setup, define secret keys and URLs during the initial `better-auth` installation. This connects your auth server and client instances to external social login providers securely.
