OTP Forge

A simple library for managing OTPs for all your applications. It helps with the generation, storage and verification of OTPs.

Getting Started

These instructions will give you a copy of the project up and running on your local machine for development and testing purposes.

Installing

Requirements:

• Node.js (version >= 16.0.0)

Install with:

NPM:

npm install @otp-forge/otp-forge

Yarn:

yarn add @otp-forge/otp-forge

PNPM:

pnpm add @otp-forge/otp-forge

pnpm

How To Use

Initialize the OTPManager with the required configuration options:

const OTPManager = require("@otp-forge/otp-forge");

// In memory storage
const passwordResetOTPManager = new OTPManager({
  // Configuration options
  purpose: "password-reset", // Purpose of the OTP
  otpLength: 6, // Length of the OTP
  expirationTime: 300, // Time to live in seconds
});

Generate an OTP:

const otp: number = await passwordResetOTPManager.generateOTP();

Verify an OTP:

const isValid: boolean = await passwordResetOTPManager.verifyOTP(otp);

Warning: The default store is in-memory, which means that the OTPs will be lost when the application is restarted. To use a persistent store, you can use one of the supported stores or build your own.
