# Tool Highlight: Better Auth — the Auth You Own Instead of Rent

> A framework-agnostic TypeScript library that puts login, 2FA, passkeys, and multi-tenant orgs in your codebase — with the user table in your own database. Working sign-in in about ten minutes, and no per-user bill ever.

**What it is:** [Better Auth](https://www.better-auth.com) is an open-source, MIT-licensed authentication library for TypeScript that runs *inside your application* instead of on someone else's servers. Login, sessions, two-factor, passkeys, and multi-tenant organizations — all in your codebase, all writing to *your* database. About 29,000 GitHub stars, framework-agnostic, and free.
**Who makes it:** The Better Auth open-source project (`better-auth/better-auth`), MIT-licensed and written in TypeScript. It's one of the fastest-rising auth projects of the last two years, and the reason is boring in the best way: it does the whole job, not a slice of it.
**Why it's here:** Hosted auth providers meter your users and hold their identity records. Better Auth's per-user cost is structurally zero — it's a library, so you pay for your database and nothing else. For a solo founder or a small team watching the burn, that's not a rounding error; it's the difference between a flat database bill and an invoice that grows with every signup. (For the full cost-at-scale case against renting, see [Better Auth vs Clerk vs Auth0](/posts/better-auth-vs-clerk-vs-auth0-own-or-rent.html).)
Start it in about ten minutes
Install the package:
```
npm install better-auth
```
Create the server instance — a secret, your database, and whichever methods you want turned on:
```
// lib/auth.ts
import { betterAuth } from "better-auth";
import { passkey } from "better-auth/plugins/passkey";

export const auth = betterAuth({
  secret: process.env.BETTER_AUTH_SECRET,
  database: yourDatabaseAdapter,        // Postgres / MySQL / SQLite
  emailAndPassword: { enabled: true },
  socialProviders: {
    github: {
      clientId: process.env.GITHUB_CLIENT_ID!,
      clientSecret: process.env.GITHUB_CLIENT_SECRET!,
    },
  },
  plugins: [passkey()],                 // passwordless, WebAuthn
});
```
Mount the handler on one catch-all route (Next.js shown; the pattern is the same for SvelteKit, Nuxt, Remix, Astro, or plain Node):
```
// app/api/auth/[...all]/route.ts
import { auth } from "@/lib/auth";
import { toNextJsHandler } from "better-auth/next-js";

export const { GET, POST } = toNextJsHandler(auth);
```
Generate the schema (`npx @better-auth/cli generate`), and you have working email/password, GitHub login, and passkeys writing to your own tables. Signing a user in from the client is one call:
```
import { authClient } from "@/lib/auth-client";

await authClient.signIn.social({ provider: "github" });
// or passwordless:
await authClient.signIn.passkey();
```
What you actually get
Everything you'd normally rent ships as a plugin you switch on:
- **Social + email/password** login out of the box.
- **Two-factor** (`twoFactor()`) — TOTP and OTP flows.
- **Passkeys/WebAuthn** (`passkey()`) — including *conditional UI*, so the browser autofills a saved passkey with no button-press ceremony. ([Full passkey walkthrough here.](/posts/how-to-add-passkeys-passwordless-login.html))
- **Multi-tenant organizations** (`organization()`) — orgs, members, and invitations for team products.

The honest tradeoff
You're taking on the security surface. Sessions, rate-limiting, credential storage, and keeping the library patched are your job now, not a vendor's. Better Auth hands you tested defaults for all of it, but the operational duty moves in-house.
That's the deal, stated plainly: **you trade a vendor's per-user invoice and their custody of your users for a flat database bill and your own responsibility.** For most product-shaped apps — especially early ones optimizing for runway and optionality — that's the trade you want. And it's the one migration you can't easily do later: keeping identity data in your own database from day one is free; clawing it back from a hosted provider is not.
