# Two-Column Login Card V0 Template: Testimonial + Auth Form, Forked in Minutes - Tool: V0 Templates - Last updated: July 2026 ## TL;DR The Two-Column Login Card template pairs a shadcn/ui Card on the left (testimonial quote, customer avatar, or brand illustration) with a shadcn/ui Card on the right (email input, password input, remember-me checkbox, sign-in button). Built with react-hook-form and Zod on Next.js, it's the cleaner card-style alternative to the full-bleed hero panel login. Fork it, update the testimonial, and use the prompt pack to wire it to Clerk or Supabase in under an hour. ## Frequently asked questions ### Is the Two-Column Login Card v0 template free? Yes. Fork it for free with a free V0 account. The generated code is yours with no licensing fees. shadcn/ui, react-hook-form, and Zod are all MIT-licensed open-source libraries. ### Can I use this template commercially in a product I sell? Yes. The code V0 generates is yours to use in any commercial product without restriction. Don't republish the template on v0.dev community as your own creation. ### Why does my fork show a blank preview after I add Supabase? V0's preview sandbox resolves npm packages through esm.sh. @supabase/ssr sometimes fails there with 'Import Error | Failed to load from blob...'. This is a preview sandbox limitation only — click Share → Publish to Production and test on the Vercel deployment where the package resolves correctly. ### Why is the Remember Me checkbox causing a server error? V0 sometimes places localStorage.getItem() directly in the component render body, which runs during Next.js SSR in Node.js where localStorage doesn't exist. Move all localStorage reads and writes into a useEffect hook — this ensures they only run in the browser after the component mounts. ### How do I fix the mobile layout where both cards stack vertically? Change the grid from grid-cols-2 to grid-cols-1 md:grid-cols-2 and add hidden md:block to the left testimonial card. On screens smaller than the md breakpoint (768px), only the right form card shows. Add max-w-sm mx-auto to the right card so it doesn't stretch too wide on tablets. ### What's the difference between this and the Two-Column Login template? This template uses a shadcn/ui Card on the left with a testimonial — more structured and constrained. The Two-Column Login template uses a full-height image panel with marketing copy overlaid on it — more visual impact. Both share the same right-column auth form. Choose card for B2B SaaS trust signals; choose image panel for consumer apps. ### Can RapidDev wire this login card to Clerk or Supabase for me? Yes. RapidDev wires this V0 login card to your auth provider, adds protected route middleware, configures OAuth callbacks, and ships the complete auth flow — typically in 1 day. ### How do I cycle through multiple testimonials in the left card? Use the 'Animate the left card testimonial on repeat' prompt from the prompt pack above. It installs framer-motion, creates a testimonials array, and uses setInterval in a useEffect to rotate through them every 5 seconds with a fade-slide transition — no page reload required. --- Source: https://www.rapidevelopers.com/v0-template/two-column-login-card © RapidDev — https://www.rapidevelopers.com/v0-template/two-column-login-card
