Installation

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.
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.

⚠️ 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.
