Email Verification using OTP in NodeJS

Last Updated : 19 Feb, 2021

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"); 

We have created an OTP verification service.<
