Neon Auth is a newly introduced fully managed authentication solution within the Neon platform, designed to streamline the process of provisioning authentication services with a few clicks while avoiding vendor lock-in. By using Stack Auth as the initial provider, Neon Auth automates the synchronization of user profiles with your Postgres database, eliminating the need for manual synchronization methods like webhooks or background jobs. The system allows users to retain full control over their authentication layer, even if they transition away from Neon, by storing authentication data directly in the database, which facilitates easier migration between providers. Neon Auth simplifies user data management by exposing user data as a standard Postgres table and ensures continuous synchronization with sub-second delays, promoting seamless integration of authentication into applications. The service is currently in Beta and aims to expand with additional authentication providers like Clerk, offering more options for users in the future.
