OTP Input
Design System - OTP input component
The OTP Input component is designed to collect secure, time-sensitive verification codes from users in a clear and accessible way. It emphasises clarity, accuracy, and ease of use across different devices, ensuring a smooth authentication process.
// Sample code
<CheckBox
label="Label"
onChange={(e)=>{console.log(e.target.checked}}
/>Anatomy
Variants
4-characters
Used when the OTP is limited to four digits, offering a compact layout ideal for simpler authentication flows.
6-characters
Common in more secure flows, this variant provides six input boxes for enhanced verification.
Properties
Label Positioned above the input fields (e.g., "Enter OTP"), it provides clear instructions to the user.
Error Displays an error message (e.g., “Invalid OTP”) with a red border and icon to indicate incorrect input.
Masking
Optionally replaces typed characters with dots (●) for added security, particularly useful in shared or public environments.
Property Configuration Table
Each design component offers a range of configurable options. These options are intentionally platform-agnostic, allowing implementations to adapt and tailor them to align with the specific requirements of the chosen framework.

Interaction State
Single Focus In Single Focus mode, only one input box is actively focused at a time. As the user types, the focus automatically moves to the next box, improving usability and reducing the need for manual navigation between fields.
Behaviours
Auto Tabbing
The cursor automatically jumps to the next field as each digit is entered.
Backspace Navigation
Pressing backspace in an empty field moves the focus to the previous box, allowing easy correction.
Paste Handling
Supports pasting a full OTP string, automatically distributing characters across input fields.
Usage Guide
Use Clear Focus State for Better User Guidance
Ensure that the currently active OTP input field is visually distinct so users can immediately recognise where they need to type next. A proper focus state improves accessibility and enhances the user experience by providing clear feedback on input interactions. Users should not struggle to identify which input box is currently active. Lack of clear focus indication can result in hesitation or mistakes, causing frustration.
