Email Verification using OTP in NodeJS

This Article speaks about setting up your node.js server for verifying emails via OTP.

Project setup: The name of the package is two-step-auth

Installation:

npm i --save two-step-auth

Default Usage:

Kindly Provide a Company Name so the mail will be treated as important. (This is optional)
Import the Auth object from the package and use them as mentioned below.

Folder Structure:

Code Template:

const { Auth } = require("two-step-auth"); 

async function login(emailId) { 

  const res = await Auth(emailId); 

  // You can follow this approach, 

  // but the second approach is suggested, 

  // as the mails will be treated as important 

  const res = await Auth(emailId, "Company Name"); 

  console.log(res); 

  console.log(res.mail); 

  console.log(res.OTP); 

  console.log(res.success); 
} 

login("verificationEmail@anyDomain.com");

Once if the operation is success, we will have the OTP in hand, and an Email will be sent to the particular user’s mail ID
Custom Email ID usage :
- Pull the LoginCredentials object from the package and use them as mentioned below
- Prerequisites for using custom Email ID :
  - Make sure you have enabled the allow less secure apps for that particular account before executing the function.
  - Turn them Off when not in use.

Example:

index.js

const { Auth, LoginCredentials } = require("two-step-auth"); 

async function login(emailId) { 

  try { 

    const res = await Auth(emailId, "Company Name"); 

    console.log(res); 

    console.log(res.mail); 

    console.log(res.OTP); 

    console.log(res.success); 

  } catch (error) { 

    console.log(error); 

  } 
} 

// This should have less secure apps enabled 

LoginCredentials.mailID = "yourmailId@anydomain.com";  

// You can store them in your env variables and 
// access them, it will work fine 

LoginCredentials.password = "Your password";  

LoginCredentials.use = true; 

// Pass in the mail ID you need to verify 

login("verificationEmail@anyDomain.com");
