Neon has launched an updated version of its authentication service, Neon Auth, which integrates user, role, and session management directly into the Neon database, allowing for seamless branching and testing of authentication workflows in isolated environments. This overhaul eliminates the need for external identity providers and webhook synchronization, reducing complexity and enhancing developer experience by storing all authentication data in the neon_auth schema. The new system, based on the Better Auth framework, provides a robust and extensible foundation that supports automatic session handling and JWT management. With this integration, developers can now run authentication directly within their Neon's database infrastructure, maintaining real-time consistency and low-latency requests. The update also simplifies compliance testing, offers enhanced security management, and supports more efficient branching, making it particularly beneficial for startups, B2B platforms, compliance-sensitive industries, and agent or codegen platforms. Neon Auth is compatible with various development setups like Next.js, React, and TanStack, and the new implementation is set to eventually replace the previous Stack Auth system.
