Better Auth Plugins

Goals

  • Add server plugins to extend auth features.
  • Add client plugins for matching client methods.
  • Apply schema changes when plugins add tables.

Quick start

  1. Import the plugin from better-auth/plugins and add it to plugins.
  2. Run migrations (generate or migrate) when required.
  3. Add the client plugin from better-auth/client/plugins.
Example: Two-factor authentication
import { betterAuth } from "better-auth";
import { twoFactor } from "better-auth/plugins";

export const auth = betterAuth({
  plugins: [twoFactor()],
});

import { createAuthClient } from "better-auth/client";
import { twoFactorClient } from "better-auth/client/plugins";

export const authClient = createAuthClient({
  plugins: [twoFactorClient({ twoFactorPage: "/two-factor" })],
});

Migration reminder

Run the CLI when a plugin adds tables:

npx @better-auth/cli generate

npx @better-auth/cli migrate

Guardrails

  • Add server and client plugins together to keep APIs aligned.
  • Keep nextCookies (if used) last in the server plugin list.
  • Review plugin docs for required schema and env variables.
