FAQPage Schema
How do I add authentication to a TypeScript app without being locked into a specific framework?▼

Framework-agnostic authentication for TypeScript apps eliminates framework lock-in by supporting Next.js, Nuxt, SvelteKit, Remix, Hono, and Express. You mount the API handler in your chosen framework to enable email/password, OAuth, and session management.

Can I set up OAuth and 2FA in TypeScript without writing custom security boilerplate?▼

Yes, automating TypeScript authentication setup removes security boilerplate by providing built-in OAuth2 providers, 2FA, passkeys, and magic links. You configure environment variables for secrets and OAuth credentials to enable these features securely.

What do I need to configure before implementing passkeys and RBAC in my web application?▼

Before implementing passkeys and RBAC, you need to install the auth package, configure a database adapter, and provide environment variables for secrets. You can then optionally enable specific plugins to activate WebAuthn and role-based access control.

Does this TypeScript authentication approach work with both modern meta-frameworks and standard Express servers?▼

Yes, this TypeScript authentication approach works across modern meta-frameworks and standard servers. It supports framework-agnostic server and client integration for Next.js, Nuxt, SvelteKit, Remix, Astro, Hono, and Express.

What is the best way to handle session management and password rules for TypeScript applications?▼

The best way to handle session management and password rules for TypeScript applications is using an automated auth system. It provides built-in email/password verification, robust session management, and configurable password rules without manual implementation.
