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" ); |
