# Sign in with Google V0 Template: Fork It & Wire OAuth in 30 Minutes

- Tool: V0 Templates
- Last updated: July 2026

## TL;DR

The Sign in with Google v0 template gives you a polished Auth Card with a Google Sign-In Button, optional email fallback, and loading state — built with shadcn/ui and ready to wire to Supabase or Clerk in about 30 minutes. The prompt pack covers adding GitHub OAuth, full callback handling, and post-login profile creation so you skip the boilerplate entirely.

## Frequently asked questions

### Is the Sign in with Google template free to use?

Yes. Community templates on v0.dev are free to fork. You pay only for V0 credits when you send prompts to customize the template. Forking itself and using Design Mode cost nothing.

### Can I use this template commercially?

Yes. V0 community templates are available for commercial use. The generated code is yours to use in any product, including paid SaaS applications. Review v0.dev's terms of service for the complete licensing details.

### Why does my fork show a blank screen or import error in the V0 preview?

The most common cause is the `@supabase/ssr` import failing in V0's esm.sh preview sandbox. This is a known limitation of the preview environment — the package uses Node.js APIs that can't run in the browser-based sandbox. Click Share → Publish to Production and test the OAuth flow on the live Vercel URL instead. The deployed app will work correctly.

### Do I need a Google Cloud Console account to use this template?

Yes, to enable real Google OAuth you need to create an OAuth 2.0 Client ID in Google Cloud Console and add your Vercel domain to Authorized Redirect URIs. This is a one-time setup that takes about 10 minutes. Both Supabase and Clerk have documentation walking you through the Google Cloud Console steps.

### Does this template work with Clerk or just Supabase?

It works with either. The Auth Card UI is auth-provider-agnostic. The prompt pack includes steps for both Supabase signInWithOAuth and Clerk's authenticateWithRedirect OAuth flow. Choose your provider and follow the corresponding prompt.

### Can I add more OAuth providers like GitHub or Apple?

Yes. The same Auth Card pattern supports any provider your auth library supports. The 'Add GitHub OAuth button' prompt in this playbook shows exactly how to add a second provider button below the Google Sign-In Button, reusing the same Supabase callback route.

### Can RapidDev customize this template for my product?

Yes. RapidDev wires V0 Google Sign-In to Supabase or Clerk, adds protected routes, user profile creation, and production OAuth configuration — typically delivered in 1–2 days.
