Disabled state

Disable the entire one-time password input by adding the data-coreui-disabled="true" attribute.

Disabled OTP input

html

<label class="form-label">Disabled OTP input</label>
<div class="form-otp" data-coreui-toggle="otp" data-coreui-disabled="true" data-coreui-value="123456">

  <input class="form-otp-control">
  <input class="form-otp-control">
  <input class="form-otp-control">
</div>

Readonly state

Use the data-coreui-readonly="true" attribute to make the one-time password input non-editable but still selectable.

html

<label class="form-label">Readonly OTP input</label>
<div class="form-otp" data-coreui-toggle="otp" data-coreui-readonly="true" data-coreui-value="123456">

Accessibility

The one-time password input component is designed with accessibility in mind and follows WCAG guidelines for form inputs.

ARIA Labels: Each input field automatically receives descriptive aria-label attributes
Role Attribute: The container has role="group" to indicate related form controls
Keyboard Navigation: Full keyboard support with arrow keys, tab, and backspace
Screen Reader Support: Clear announcements when values change or validation occurs
Focus Management: Automatic focus handling for seamless navigation

Customizing accessibility

You can customize the aria-label generation function to provide more specific descriptions:

const otp = new coreui.OTPInput(element, {
  ariaLabel: (index, total) => `Enter digit ${index + 1} of your ${total}-digit verification code`
})

Keyboard support

The one-time password input component provides comprehensive keyboard navigation support:

Key	Action
`Arrow Right`	Move focus to next input field
`Arrow Left`	Move focus to previous input field
`Backspace`	Delete current character and move to previous field (if empty)
`Tab`	Move to next focusable element (respects linear mode)
`Shift` + `Tab`	Move to previous focusable element
`Ctrl` + `V` / `Cmd` + `V`	Paste clipboard content and auto-fill fields

Usage

Heads up! In our documentation, all examples show standard CoreUI implementation. If you are using a Bootstrap-compatible version of CoreUI, remember to use the following changes:

In the constructor, please use bootstrap instead of coreui. For example, new bootstrap.Alert(...) instead of new coreui.Alert(...)
In events, please use bs instead of coreui, for example close.bs.alert instead of close.coreui.alert
In data attributes, please use bs instead of coreui. For example, data-bs-toggle="..." instead of data-coreui-toggle="..."

Via data attributes

The simplest way to use the one-time password input is through data attributes. Add data-coreui-toggle="otp" to a container with .form-otp class containing .form-otp-control inputs.

<div class="form-otp" data-coreui-toggle="otp">
  <input class="form-otp-control">
  <input class="form-otp-control">
  <input class="form-otp-control">
  <input class="form-otp-control">
  <input class="form-otp-control">
  <input class="form-otp-control">
</div>

Via JavaScript

Create one-time password inputs programmatically with JavaScript:

const otpElement = document.querySelector('.form-otp')
const otp = new coreui.OTPInput(otpElement, {
  type: 'number',
  autoSubmit: true,
  linear: true,
  masked: false
})

Options

Options can be passed via data attributes or JavaScript. For data attributes, append the option name to data-coreui-, as in data-coreui-type="number".

Name	Type	Default	Description
`ariaLabel`	function	`(index, total) => Digit ${index + 1} of ${total}`	Function to generate aria-label for each input field. Receives current index (0-based) and total number of inputs
`autoSubmit`	boolean	`false`	Automatically submit the form when all OTP fields are filled
`disabled`	boolean	`false`	Disable all OTP input fields
`id`	string, null	`null`	ID attribute for the hidden input field
`linear`	boolean	`true`	Enforce sequential input (users must fill fields in order)
`masked`	boolean	`false`	Show input as password (masked characters)
`name`	string, null	`null`	Name attribute for the hidden input field
`placeholder`	string, null	`null`	Placeholder text for input fields. Single character applies to all fields, longer strings apply character-by-character
`readonly`	boolean	`false`	Make OTP input read-only
`required`	boolean	`false`	Makes the input field required for form validation.
`type`	string	`'number'`	Input validation type: ’number’ for digits only, or any other string for free text
`value`	string, number, null	`null`	Initial value for the OTP input

Methods

Method	Description
`clear`	Clear all OTP input fields
`reset`	Reset OTP input to its initial value
`update`	Update the OTP input configuration

const otp = coreui.OTPInput.getInstance(document.querySelector('.form-otp'))
otp.clear() // Clear all fields
otp.reset() // Reset to initial value
otp.update({ type: 'number', masked: true }) // Update configuration

Events

Event	Description
`change.coreui.otp-input`	Fired whenever the OTP value changes
`complete.coreui.otp-input`	Fired when all OTP fields are filled

document.addEventListener('change.coreui.otp-input', event => {
  // eslint-disable-next-line no-console
  console.log('OTP value changed:', event.value)
})

document.addEventListener('complete.coreui.otp-input', event => {
  // eslint-disable-next-line no-console
  console.log('OTP completed:', event.value)
})
