About
Better Auth is a framework-agnostic authentication and authorization framework for TypeScript that runs inside your own codebase. It ships with a comprehensive set of built-in features including 2FA, passkeys, multi-tenancy, SSO, and more, all extendable via a plugin system. An optional hosted infrastructure layer adds a dashboard, audit logs, and real-time security threat detection.
Problem
Implementing secure, feature-rich authentication from scratch is complex and time-consuming for developers.
For
TypeScript developers building web applications from side projects to enterprise scale
How it works
Developers install Better Auth into their TypeScript project and compose authentication features through a plugin-based API, optionally connecting to hosted infrastructure for dashboards and security detection.
