When to use it

Use OTP Input for one-time codes: two-factor sign-in, email verification, phone confirmation. Pasting a whole code fills every box, SMS autofill works on phones, and onComplete fires as soon as the last box is filled, so people never have to press Submit.

Installation

How you get it

Paste this into Claude Code, Cursor, Codex or any coding agent. It installs the file and uses it as it is, instead of writing a new one.

Use Liro's OTP Input for this.
Install it: npx shadcn@latest add @liro/otp-input
(the @liro registry is set up in components.json, with LIRO_KEY in .env.local)
Import it from @/components/ui/otp-input.
Do not rewrite or restyle it. Pass my data through its props
and keep its built-in states.

For the full brief with every prop and the mistakes assistants usually make, use Copy prompt above. Free components install through the @liro registry with your CLI token: see the Namespaced tab.

Usage

components/verify-code.tsx
"use client";

import { OtpInput } from "@/components/ui/otp-input";

export function VerifyCode({ verify }: { verify: (code: string) => void }) {
  return <OtpInput length={6} aria-label="Verification code" autoFocus onComplete={verify} />;
}

Accessibility

  • Keyboard reachable throughout, in visual order
  • Focus trapped in overlays, Escape closes them
  • Focus returns to whatever opened it
  • Live regions announce what changed, not that something did
  • Honours prefers-reduced-motion

Responsive behavior

  • Sizes to its container, not the viewport
  • Usable from 320px up
  • Pointer-based interaction, so trackpad and touch both work
  • No hover-only affordances
