Auth30: PIN Keypad Unlock

Full-height numeric lock screen: a row of dots that fill in as digits are entered, a 3x3 numeric keypad with a biometric shortcut and backspace flanking the 0 key, and an optional forgot-PIN link underneath.

Installation

Radix flavor

npx shadcn add "https://ui.beste.co/r/auth30"

Base UI flavor

npx shadcn add "https://ui.beste.co/r-base/auth30"

This installs the block to components/beste/block/auth30.tsx and its dependencies.

Quick start

The installed file exports auth30Demo alongside the block: the exact props behind the preview above. Spread it to get a working PIN lock screen in one line.

import { Auth30, auth30Demo } from "@/components/beste/block/auth30";

export default function UnlockPage() {
  return <Auth30 {...auth30Demo} />;
}

Then replace the demo with your own props. Written out, a trimmed setup looks like this:

import { Auth30 } from "@/components/beste/block/auth30";

export default function UnlockPage() {
  return (
    <Auth30
      heading="Enter your PIN"
      description="Use your 4-digit PIN to unlock your account."
      pinLength={4}
      labels={{ biometric: "Use biometrics", backspace: "Delete" }}
      forgotPrompt={{ text: "Forgot your PIN?", linkLabel: "Reset it", href: "/reset-pin" }}
    />
  );
}

Behavior notes

• The entered PIN is fully internal useState<string>; there is no onChange, onComplete, or any other callback prop, so the component never tells the outside world when the PIN reaches pinLength or what its value is. An integrator wiring this to real auth needs to fork the component to lift that state out.
• Digits are capped at pinLength by append(), but reaching the cap does nothing on its own, no auto-submit, no visual "complete" state beyond all dots being filled.
• The biometric button renders only when labels.biometric is set; it has an aria-label but no onClick handler at all, so it is purely decorative in the shipped code and needs to be wired up.
• The backspace button is disabled whenever the PIN is empty; digit buttons themselves have no disabled state once the PIN is full, they simply stop appending because append() checks the length.
• Digits 1-9 come from a mapped array in a grid-cols-3 layout; 0 is a separate hardcoded button placed in the bottom row between the biometric shortcut and backspace, matching a standard phone keypad arrangement.
