# Next.js SaaS starter with Email & Password

Ship Email & Password in your Next.js app with sessions, protected routes, and email auth working together. Skip the callback wiring, cookie edge cases, and deploy surprises that stall most OAuth rollouts.

## The problem

Rolling your own Email & Password in Next.js means OAuth callbacks, session storage, CSRF edges, and protected routes that break the first time you deploy to production.

Scaffold Next.js, find a Email & Password tutorial, wire env vars, fix auth sessions, then repeat for billing and email. Most teams lose weeks before the stack deploys cleanly or handles real users.

## Why LaunchFast

LaunchFast is a production Next.js repo where Email & Password already talks to auth, billing, and deployment. Add your keys, customize the UI, and ship while the cross-cutting SaaS plumbing stays done.

### Benefits

- Email and password sign-up with hashed credentials
- Email verification and forgot-password flows included
- Works alongside Google, GitHub, and magic-link auth

## How it works

### Clone and configure

Add your Email & Password keys and provider settings to the included env template. The Next.js app boots with the integration active.

### Customize product flows

Adjust pages, pricing, and onboarding on top of pre-wired routes. Auth, webhooks, and integration helpers stay intact.

### Deploy with included configs

Use the bundled Vercel, Cloudflare Workers, or Node deployment setup. Sessions and webhooks are tuned for production, not just localhost.

### Swap providers later

Client wants a different payment processor or database? Change adapters through config instead of rewriting your Next.js app.

## FAQ

### Is this only about Email & Password?

No. The Next.js kit is a complete SaaS foundation. Email & Password ships alongside auth, billing, email, analytics, storage, and deployment so you are not assembling the stack from scattered tutorials.

### Can I see it working before I buy?

Yes. The live demo runs the same Next.js starter with real auth and billing flows. Open the demo, click through signup and checkout, then compare with your timeline.

### What if I need Astro or SvelteKit instead?

LaunchFast ships the same integration surface in all three frameworks. Related links on this page point to the Email & Password guides for Astro and SvelteKit too.
