Riassunto

Authentication seems simple—until sessions expire incorrectly, OAuth callbacks fail, permissions leak data, or one tenant gains access to another tenant’s resources.

Better Auth for Secure TypeScript Applications gives you a practical, step-by-step path from basic sign-in to a production-ready identity system using Better Auth, TypeScript, Next.js, PostgreSQL, and Drizzle.

You do not need previous experience with Better Auth, OAuth, OpenID Connect, WebAuthn, enterprise SSO, or identity security. The book introduces each concept gradually, explains the reasoning behind important security decisions, and builds one connected application as your skills grow.

Instead of memorizing configuration, you will learn how authentication works, where security boundaries belong, what can go wrong, and how to test your assumptions. Mistakes are treated as part of the learning process: failed callbacks, rejected sessions, broken permission checks, and unsuccessful tests become opportunities to understand the system more deeply.

Key Features

• Hands-on, step-by-step development with Better Auth and Next.js

• Practical TypeScript examples built around one evolving application

• Secure sessions, cookies, account recovery, and social authentication

• Passkeys, WebAuthn, two-factor authentication, and trusted devices

• Organizations, teams, roles, permissions, and access control

• Enterprise SSO with OIDC and SAML

• SaaS multi-tenancy and tenant-isolation patterns

• API authentication, API keys, abuse prevention, and security hardening

• Testing, audit trails, observability, incident response, and production deployment

• Practical exercises, production references, security checklists, and terminology guides

What You Will Learn

Build secure registration, login, verification, logout, and recovery flows; manage session expiration and revocation; integrate OAuth providers; implement passkeys and stronger authentication; design role-based access control; secure organization and tenant data; configure enterprise SSO; protect browser and machine APIs; test failure paths; monitor authentication events; and prepare your identity system for production.

Who This Book Is For

This book is for TypeScript and web developers who understand basic web development but are new to authentication architecture. It is especially useful for self-learners, junior-to-intermediate developers, SaaS builders, and developers who want a practical introduction to secure authentication without starting from advanced identity-security theory.
