Neon Auth

Neon Auth is Managed Better Auth: users, sessions, and auth config live in the neon_auth schema on the branch's Lakebase Postgres, and auth state branches with the database. The client API is the Better Auth method set (signIn.email, signIn.social, getSession) through @neondatabase/auth. That wrapper is not a drop-in for bare better-auth/client: it pins the plugin list and adds Neon-specific OAuth verifier, iframe popup, and JWT handling. Stay on the wrapper while Auth is managed.

This skill chooses identity, then implements Managed Better Auth. It does not replace a working auth server in order to use Postgres, Functions, Object Storage, or the AI Gateway.

When to Use

Inspect existing identity and the required login features before provisioning. A supplied DATABASE_URL is not a reason to change identity. Adding a Neon Function is not a reason to change identity.
