Adding authentication to a TypeScript app is automated by configuring Better Auth modules, wiring framework route handlers, and running migrations to establish a secure auth system with minimal boilerplate.

Migrating existing authentication to Better Auth is supported through structured server and client configuration, allowing you to transition securely while integrating new feature plugins like 2FA and SSO.

Integrating 2FA, SSO, and session management plugins is fully supported during the Better Auth setup, allowing you to extend your core authentication system with advanced security features.

This authentication setup works for both new TypeScript projects starting from scratch and existing JavaScript applications that require a scalable, secure auth layer migration.

To set up server and client auth modules, you need to install Better Auth, configure environment variables, define your auth.ts and auth-client.ts files, and connect the framework route handler.

Limitations when using Better Auth for JavaScript routing and migrations are minimal, as it provides a best-practices blueprint designed to minimize boilerplate while satisfying core secure auth requirements.
