Pinput

Pinput is an open-source user interface component designed to collect short codes, such as PINs or verification codes, from users. It is commonly used in authentication flows, account verification, and two-factor authentication.

The component renders a sequence of small input elements, one per code character. It handles focus movement as the user types, supports backspace navigation, and allows users to paste a full code to fill multiple fields at once. It can be configured for numeric or alphanumeric codes and a configurable length.

Accessibility and keyboard support are central to Pinput’s design. The component typically exposes ARIA attributes, keyboard handlers, and proper focus management to work with screen readers and assistive technology.

Usage commonly involves installing the library from a package registry, importing the Pinput component, and supplying props such as length (code length), value (or controlled state), and onChange or onComplete callbacks. Styling can be customized to match an application's design system.

In practice, Pinput is used anywhere short verification codes are required, including login flows, password resets, and multi-factor authentication. It is built to be lightweight and easily integrated into existing forms without requiring a full custom input group.
