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

Import the plugin from
```
better-auth/plugins
```
and add it to
```
plugins
```
.
Run migrations (
```
generate
```
or
```
migrate
```
) when required.
Add the client plugin from
```
better-auth/client/plugins
```
.

Example: Two-factor authentication

ts

import { betterAuth } from "better-auth";
import { twoFactor } from "better-auth/plugins";

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

ts

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:

bash

npx @better-auth/cli generate
