What is an OTP Verification Component?

What is an OTP Verification Component?

An OTP Verification Component is a simple React app project that simulates the complete One-Time Password authentication workflow used in modern applications.

It allows users to generate an OTP, enter it across multiple input fields, and provides features such as automatic focus movement to the next input, backspace navigation, and paste support to quickly enter all digits at once.

Once all four digits are entered, the component automatically triggers OTP verification, displays a loading state to simulate an API request, and validates the entered OTP against the generated one.

It also includes resend-OTP functionality with a 30-second countdown timer to prevent repeated requests, along with clear success and error messages to improve the overall user experience and make the verification flow feel more like a real-world authentication system.

Please Note:

Since this is a frontend-only project without a backend service to send real OTPs via SMS or email, the OTP is generated and displayed using the browser's alert() function to simulate the complete verification workflow.
