Live Demo

Installation

To install the latest stable version:

npm install --save react-otp-input

Still using v2?

No problem! You can find the documentation for v2 here

Basic usage:

import React, { useState } from 'react';
import OtpInput from 'react-otp-input';

export default function App() {
  const [otp, setOtp] = useState('');

  return (
    <OtpInput
      value={otp}
      onChange={setOtp}
      numInputs={4}
      renderSeparator={<span>-</span>}
      renderInput={(props) => <input {...props} />}
    />
  );
}

API

You can also pass a function that returns a component, where the function will get the index of the separator being rendered as an argument.

Name	Type	Required	Default	Description
numInputs	number	true	4	Number of OTP inputs to be rendered.
renderInput	function	true	none	A function that returns the input that is supposed to be rendered for each of the input fields. The function will get two arguments: inputProps and index. inputProps is an object that contains all the props that should be passed to the input being rendered (Overriding these props is not recommended because it might lead to some unexpected behaviour). index is the index of the input being rendered.
onChange	function	true	console.log	Returns OTP code typed in inputs.
onPaste	function	false	none	Provide a custom onPaste event handler scoped to the OTP inputs container. Executes when content is pasted into any OTP field. Example: const handlePaste: React.ClipboardEventHandler = (event) => { const data = event.clipboardData.getData('text'); console.log(data) };
value	string / number	true	''	The value of the OTP passed into the component.
placeholder	string	false	none	Specify an expected value of each input. The length of this string should be equal to numInputs.
renderSeparator	component / function	false	none	Provide a custom separator between inputs by passing a component. For instance, <span>-</span> would add - between each input.
containerStyle	style (object) / className (string)	false	none	Style applied or class passed to container of inputs.
inputStyle	style (object) / className (string)	false	none	Style applied or class passed to each input.
inputType	<input> type	false	text	The type of the input that will be passed to the input element being rendered. In v2 isInputNum used to set the input type as tel and prevented non numerical entries, so as to avoid the spin buttons added to the inputs with input type number. That behaviour is still supported if you pass tel to the inputType prop.
shouldAutoFocus	boolean	false	false	Auto focuses input on initial page load.
skipDefaultStyles	boolean	false	false	The component comes with default styles for legacy reasons. Pass true to skip those styles. This prop will be removed in the next major release.

⚠️ Warning

Do not override the following props on the input component that you return from the renderInput prop. Doing so might lead to unexpected behaviour.

• ref
• value
• onChange
• onFocus
• onBlur
• onKeyDown
• onPaste
• onInput
• type
• inputMode

Migrating from v2

The v3 of react-otp-input is a complete rewrite of the library. Apart from making the API more customizable and flexible, this version is a complete rewrite of the library using TypeScript and React Hooks. Here are the breaking changes that you need to be aware of:

• You now need to pass your own custom input component that will be rendered for each of the input fields via renderInput prop. This gives you the flexibility to customize the input fields as you desire. This also means that props like focusStyle, isDisabled, disabledStyle, hasErrored, errorStyle, isInputNum, isInputSecure, data-cy and data-testid are no longer supported. You can achieve the same functionality and more by passing the relevant props directly to the input component that you return from the renderInput prop.

• The separator prop has now been renamed to renderSeparator. This prop now apart from accepting a component that will be rendered as a separator between inputs like it used to, now also accepts a function that returns a component. The function will get the index of the separator being rendered as an argument.

• A new prop called inputType has been added to the component. This prop can be used to specify the type of the input that will be passed to the input element being rendered. The default value of this prop is number.

Migrating from v1

react-otp-input is now a controlled component to facilitate functionalities that weren't possible before from the application using it, such as clearing or pre-assigning values. For v1.0.0 and above, a value prop needs to be passed in the component for it to function as expected.
