Introducing Convex Auth

Convex Auth is a library designed to simplify the implementation of authentication in multi-user applications using the Convex backend. It addresses the complexity of integrating authentication into full-stack apps by providing a self-hosted solution that offers developers more control over their data and a simpler architecture compared to third-party platforms like Clerk and Auth0, which store authentication data externally and require synchronization with backends and databases. Inspired by libraries such as Auth.js and Lucia, Convex Auth supports various sign-in methods, including OAuth, magic links, one-time passwords, and traditional email-password combinations, with compatibility for 80 OAuth providers. The setup involves configuring server files like auth.ts to define available authentication methods and frontend components to manage authentication states. This allows developers to build a user authentication system that is both flexible and scalable, while also ensuring efficient data handling within their applications.
