Better Auth Authentication

Goals

• Enable email/password authentication and social providers.
• Implement sign-up, sign-in, sign-out, and verification flows.
• Handle redirects and errors consistently.

Quick start

1. Enable emailAndPassword and configure socialProviders.
2. Create a client with createAuthClient.
3. Use signUp.email, signIn.email, signIn.social, and signOut on the client.

import { betterAuth } from "better-auth";

export const auth = betterAuth({
  emailAndPassword: { enabled: true },
  socialProviders: {
    github: {
      clientId: process.env.GITHUB_CLIENT_ID as string,
