Better Auth is an authentication library for adding account and session workflows to applications. It provides reusable building blocks for sign-in and related account features, helping you avoid designing the entire authentication system yourself.

Explore sign-in, session, and provider options when your application needs to identify users and protect their personal workspace.
Extend account workflows
Use its plugin approach for additional authentication needs as the product grows. This is useful when the account system must evolve alongside new features.
