What is better-auth?

Better Auth is a framework-agnostic authentication and authorization library for TypeScript applications. It handles email and password sign-in, social and OAuth2 / OpenID Connect providers, sessions and two-factor authentication in your own codebase and database, rather than delegating them to a hosted identity service, and it can be extended through a plugin ecosystem.
