 title: Authentication Server Primitives

-This guide covers the **server-side primitives** for building authentication in TanStack Start: session cookies, session lookup, OAuth, password-reset hardening, CSRF, and rate limiting. It pairs with the [routing-side guide](../../../../router/guide/authenticated-routes.md) (`_authenticated` layout, `beforeLoad`, redirects, RBAC).

 If you can use a managed solution like [Clerk](https://go.clerk.com/wOwHtuJ) or [WorkOS](https://workos.com/), prefer that — they handle most of what this guide describes. Read on if you're rolling your own.
