better-auth
Status : Production Ready
Last Updated : 2026-04-08
Package : better-auth@1.6.0 (ESM-only)
Dependencies : Drizzle ORM or Kysely (required for D1 complex use cases; D1 native support available in v1.5+)
Quick Start (5 Minutes)
Installation Option 1: Drizzle ORM (Recommended)
bun add better-auth drizzle-orm drizzle-kit
bun add better-auth kysely @noxharmonium/kysely-d1
⚠️ v1.4.0+ Requirements better-auth v1.4.0+ is ESM-only . Ensure:
Upgrading from v1.3.x? Load references/migration-guide-1.4.0.md
Upgrading from v1.4.x? Load references/migration-guide-1.5.0.md
⚠️ CRITICAL: D1 Adapter Requirements v1.5.0+ : D1 is now natively supported. Pass your D1 binding directly:
import { betterAuth } from "better-auth" ;
const auth = betterAuth ({
database : env.DB ,
});
For complex schemas, use Drizzle ORM:
import { drizzleAdapter } from "better-auth/adapters/drizzle" ;
import { drizzle } from "drizzle-orm/d1" ;
const auth = betterAuth ({
database : drizzleAdapter (drizzle (env.DB , { schema }), { provider : "sqlite" }),
});
import { d1Adapter } from 'better-auth/adapters/d1'
Minimal Setup (Cloudflare Workers + Drizzle) wrangler d1 create my-app-db
2. Define Schema (src/db/schema.ts):
import { integer, sqliteTable, text } from "drizzle-orm/sqlite-core" ;
export const user = sqliteTable ("user" , {
id : text ().primaryKey (),
name : text ().notNull (),
email : text ().notNull ().unique (),
emailVerified : integer ({ mode : "boolean" }).notNull ().default (false ),
image : text (),
});
export const session = sqliteTable ("session" , {
id : text ().primaryKey (),
userId : text ().notNull ().references (() => user.id , { onDelete : "cascade" }),
token : text ().notNull (),
expiresAt : integer ({ mode : "timestamp" }).notNull (),
});
3. Initialize Auth (src/auth.ts):
import { betterAuth } from "better-auth" ;
import { drizzleAdapter } from "better-auth/adapters/drizzle" ;
import { drizzle } from "drizzle-orm/d1" ;
import * as schema from "./db/schema" ;
export function createAuth (env : { DB: D1Database; BETTER_AUTH_SECRET: string } ) {
const db = drizzle (env.DB , { schema });
return betterAuth ({
baseURL : env.BETTER_AUTH_URL ,
secret : env.BETTER_AUTH_SECRET ,
database : drizzleAdapter (db, { provider : "sqlite" }),
emailAndPassword : { enabled : true },
});
}
4. Create Worker (src/index.ts):
import { Hono } from "hono" ;
import { createAuth } from "./auth" ;
const app = new Hono <{ Bindings : Env }>();
app.all ("/api/auth/*" , async (c) => {
const auth = createAuth (c.env );
return auth.handler (c.req .raw );
});
export default app;
bunx drizzle-kit generate
wrangler d1 migrations apply my-app-db --remote
wrangler deploy
Decision Tree Is this a new/empty project?
├─ YES → New project setup
│ 1. Identify framework (Next.js, Nuxt, Workers, etc.)
│ 2. Choose database (D1, PostgreSQL, MongoDB, MySQL)
│ 3. Install better-auth + Drizzle/Kysely
│ 4. Create auth.ts + auth-client.ts
│ 5. Set up route handler (see Quick Start above)
│ 6. Run migrations (Drizzle Kit for D1)
│ 7. Add features via plugins (2FA, organizations, etc.)
│
└─ NO → Does project have existing auth?
├─ YES → Migration/enhancement
│ • Audit current auth for gaps
│ • Plan incremental migration
│ • See references/framework-comparison.md for migration guides
│
└─ NO → Add auth to existing project
1. Analyze project structure
2. Install better-auth + adapter
3. Create auth config (see Quick Start)
4. Add route handler to existing routes
5. Run schema migrations
6. Integrate into existing pages/components
Critical Rules
MUST DO ✅ Use better-auth/minimal + adapter packages for smallest bundle (v1.5+)
✅ Use npx auth migrate and npx auth generate for CLI commands (v1.5+)
✅ Set BETTER_AUTH_SECRET via wrangler secret put
✅ Configure CORS with credentials: true
✅ Match OAuth callback URLs exactly (no trailing slash)
✅ Apply migrations to local D1 before wrangler dev
✅ Use camelCase column names in schema
NEVER DO ❌ Use d1Adapter (doesn't exist)
❌ Forget CORS credentials or mismatch OAuth URLs
❌ Use snake_case columns without CamelCasePlugin
❌ Skip local migrations or hardcode secrets
❌ Leave sendVerificationEmail unimplemented
⚠️ v1.5.0 Breaking Changes - import { apiKey } from "better-auth/plugins" ;
+ import { apiKey } from "@better-auth/api-key" ;
Schema: userId → referenceId, new configId field.
After Hooks : Database after-hooks now run post-transaction (not inside it).
Deprecated APIs Removed : Adapter → DBAdapter, InferUser/InferSession removed, @better-auth/core/utils split into subpath exports.
Load references/migration-guide-1.5.0.md when upgrading from <1.5.0
⚠️ v1.6.0 Breaking Changes Session Freshness : freshAge now uses createdAt (not updatedAt). Sessions may require re-auth more frequently for sensitive operations.
SAML Security : InResponseTo validation is default ON . Opt out with saml: { enableInResponseToValidation: false }.
OIDC Provider Deprecated : Use @better-auth/oauth-provider instead.
New in v1.5.0 (Highlights)
New CLI : npx auth init/migrate/generate/upgrade
D1 Native : Pass D1 binding directly (no adapter needed)
OAuth 2.1 Provider : @better-auth/oauth-provider (MCP-ready)
Electron : @better-auth/electron for desktop apps
i18n : @better-auth/i18n for error translations
Dynamic Base URL : Multi-domain/preview deployment support
Secret Key Rotation : Non-destructive, versioned secrets
Test Utils : Factories, OTP capture, login helpers
Typed Error Codes : Machine-readable code in error responses
Load references/v1.5-features.md for detailed implementation guides.
New in v1.6.0 (Highlights)
OpenTelemetry : Distributed tracing (experimental)
Passkey Pre-Auth : Register passkeys before session
Non-blocking Scrypt : Password hashing on libuv thread pool
46% Smaller Package : 4.2MB → 2.3MB
Case Insensitive Queries : mode: "insensitive" on adapter queries
Load references/v1.6-features.md for detailed implementation guides.

Top 5 Errors (See references/error-catalog.md for all 15)
Error #1: "d1Adapter is not exported" Problem : Trying to use non-existent d1Adapter
Solution : Use drizzleAdapter or Kysely instead (see Quick Start above)
Error #2: Schema Generation Fails Problem : better-auth migrate doesn't work with D1
Solution : Use bunx drizzle-kit generate then wrangler d1 migrations apply
Error #3: CamelCase vs snake_case Mismatch Problem : Database uses email_verified but better-auth expects emailVerified
Solution : Use camelCase in schema or add CamelCasePlugin to Kysely
Error #4: CORS Errors Problem : Access-Control-Allow-Origin errors, cookies not sent
Solution : Configure CORS with credentials: true and correct origins
Error #5: OAuth Redirect URI Mismatch Problem : Social sign-in fails with "redirect_uri_mismatch"
Solution : Ensure exact match: https://yourdomain.com/api/auth/callback/google
Load references/error-catalog.md for all 15 errors with detailed solutions.
Common Use Cases
Use Case 1: Email/Password Authentication When : Basic authentication without social providers
Quick Pattern :
await authClient.signIn .email ({
email : "user@example.com" ,
password : "password123" ,
});
emailAndPassword : {
enabled : true ,
requireEmailVerification : true ,
}
Load : references/setup-guide.md → Step 5
Use Case 2: Social Authentication (45+ Providers) When : Allow users to sign in with social accounts
Supported : Google, GitHub, Microsoft, Apple, Discord, TikTok, Twitch, Spotify, LinkedIn, Slack, Reddit, Facebook, Twitter/X, Patreon, Vercel, Kick, and 30+ more.
Quick Pattern :
await authClient.signIn .social ({
provider : "google" ,
callbackURL : "/dashboard" ,
});
socialProviders : {
google : {
clientId : env.GOOGLE_CLIENT_ID ,
clientSecret : env.GOOGLE_CLIENT_SECRET ,
scope : ["openid" , "email" , "profile" ],
},
}
Load : references/setup-guide.md → Step 5
Use Case 3: Protected API Routes When : Need to verify user is authenticated
Quick Pattern :
app.get ("/api/protected" , async (c) => {
const auth = createAuth (c.env );
const session = await auth.api .getSession ({
headers : c.req .raw .headers ,
});
if (!session) {
return c.json ({ error : "Unauthorized" }, 401 );
}
return c.json ({ data : "protected" , user : session.user });
});

v1.4.0+ new features (database joins, stateless sessions, API keys)
Migration paths, cost analysis, and performance benchmarks
Recommendations by use case and 5-year TCO
Production Examples Verified working repositories (all use Drizzle or Kysely):
zwily/example-react-router-cloudflare-d1-drizzle-better-auth - Drizzle
matthewlynch/better-auth-react-router-cloudflare-d1 - Kysely
foxlau/react-router-v7-better-auth - Drizzle
zpg6/better-auth-cloudflare - Drizzle (includes CLI)
Note : Check each repo's better-auth version. Repos on v1.3.x need v1.4.0+ migration (see references/migration-guide-1.4.0.md). None use a direct d1Adapter - all require Drizzle/Kysely.
Secure Installation When installing authentication packages, follow supply chain security best practices — auth libraries are high-value targets for supply chain attacks:
Block post-install scripts — npm config set ignore-scripts true (or Bun: disabled by default)
Cooldown period — Wait 7 days for new package versions to be vetted by the community
Audit before installing — Run socket package score npm <pkg> or use socket npm install <pkg> to check packages
Load the dependency-upgrade skill for full security configuration including Socket CLI integration, cooldown setup, lockfile validation, and CI enforcement.
Complete Setup Checklist
Check references/error-catalog.md for all 15 errors and solutions
Review references/setup-guide.md for complete 8-step setup
See references/advanced-features.md for 2FA, organizations, and more
Check official docs: https://better-auth.com
Ensure you're using Drizzle or Kysely (not non-existent d1Adapter)
