Version 3+

Basic Usage

import React, { useState } from 'react';
import AuthCode from 'react-auth-code-input';

const App = () => {
  const [result, setResult] = useState();
  const handleOnChange = (res: string) => {
    setResult(res);
  };

  return <AuthCode onChange={handleOnChange} />;
};

Mode

By default you can type numbers and letters in the inputs as the allowedCharacters prop is defaulted to alphanumeric but you can also choose between allowing only letters or only numbers by setting the prop to alpha or numeric respectively.

import React, { useState } from 'react';
import AuthCode from 'react-auth-code-input';

const App = () => {
  const [result, setResult] = useState();
  const handleOnChange = (res: string) => {
    setResult(res);
  };

  return <AuthCode allowedCharacters='numeric' onChange={handleOnChange} />;
};

Focus

By default the first input is focused when the component is mounted, you can opt-out from this by setting the autoFocus prop to false, and then you can handle the focus manually by passing a reference.

import React, { useRef, useState } from 'react';
import AuthCode, { AuthCodeRef } from 'react-auth-code-input';

const App = () => {
  const AuthInputRef = useRef<AuthCodeRef>(null);
  const [result, setResult] = useState();
  const handleOnChange = (res: string) => {
    setResult(res);
  };

  return (
    <>
      <AuthCode
        autoFocus={false}
        onChange={handleOnChange}
        ref={AuthInputRef}
      />
      <button onClick={() => AuthInputRef.current?.focus()}>Focus</button>
    </>
  );
};

Clear

You can clear all the inputs by passing a reference and then calling the clear method.

import React, { useRef, useState } from 'react';
import AuthCode, { AuthCodeRef } from 'react-auth-code-input';

const App = () => {
  const AuthInputRef = useRef<AuthCodeRef>(null);
  const [result, setResult] = useState();
  const handleOnChange = (res: string) => {
    setResult(res);
  };

  return (
    <>
      <AuthCode onChange={handleOnChange} ref={AuthInputRef} />
      <button onClick={() => AuthInputRef.current?.clear()}>Clear</button>
    </>
  );
};

This component supports autofill from SMS's received, tested on Safari and Chrome in iOS.

Changelog

3.2.1

Fix allowing non-numeric characters being introduced in numeric mode on Safari and Firefox.

3.2.0

Add placeholder prop.
Export component props.

3.1.0

Add disabled prop to disable all the inputs.
Make the backspace delete the previous character if the current is empty. Previously it just moved the focus making the user hit twice the backspace to delete the value.

3.1.0

Add autoFocus prop set to true by default to not break current usages.
Expose a focus method using references to handle the focus of the first input manually.
Expose a clear method using references to clear the input programmatically.
Add validations for when not using typescript.
Update React peerDependency to use any version 16+.

3.0.0

Change the way the allowed characters are handled by using 3 predefined modes: alpha, alphanumeric, and numeric, allowing to have more control when validating the values introduced in the inputs.
Improved logic.
Improved tests.
Improved types.
