To add authentication using Better Auth, you install the core package, configure the server in your `lib/auth.ts` file, set up client interfaces and route handlers, then run migrations. This provides a centralized global auth layer for secure sign-in and session management.

Yes, Better Auth works with Express and other Node-based frameworks. This integration supports configurable route handlers to manage authentication across different server environments, allowing you to scale user sessions safely within your existing TypeScript or JavaScript infrastructure.

The best way to centralize session management is by integrating a global authentication layer. This approach handles sign-in, sign-out, and token management through a single configured server component, reducing boilerplate and preventing security gaps in your application.

Yes, running database migrations is required. After configuring your server file with database providers and creating route handlers, you must execute migrations to generate the necessary tables for storing user credentials and session data securely.

Better Auth handles existing application migrations by providing a structured approach to layering authentication. You configure the server file, update client interfaces, and run migrations to safely transition your current user authentication flow without losing security or scalability.
