This temporary code is generated by a secure algorithm. In 2FA, apart from your email and password, you also have to enter a security code to log in. Now available with push notification support, send code request straight to your phone through the extension (current support only for Android devices).Ģ-factor authentication adds an extra layer of security to your accounts. No need to manually type in the codes ever again! This extension empowers you to easily transfer and access the 2-factor authentication codes from your mobile to your browser. Works with TOTP Authenticator mobile app. This app was kept simple for the sake of the tutorial.Get 2FA OTP instantly from your mobile. Ideally, your website should have an initial authentication method (for example, with a password set by the user), then this method will be used to add an extra layer of authentication.Īlso, secrets in your app should be kept in environment variables and you should handle errors and validation. In this tutorial, you learned how to add authentication with time-based one-time password apps like Google Authenticator. If it's all correct, you'll be authenticated and redirected to the private page. You'll see a form to enter an email and a code.Įnter the email you just used to create the account and the code from the Authenticator app. Try to log out now and go to the login page from the sign up (home) page. If it's correct, you'll be redirected to the private page. Enter that code in the 2FA Code field and click Submit. You'll see a QRCode with a code input to enter the code after scanning the QRCode.Īfter you scan the QRCode in Google's Authenticator app or any other authenticator app, you'll see a 6-digit code in the app. You'll then be redirected to add the 2FA with the authenticator app. You'll see the signup form.Įnter an email and click Sign Up. This will create the SQLite database db.sqlite and start the server at localhost:3000. In index.js add the POST route for login: This form then sends the form data to the /login POST route. Log In Log In Email Code Log In Īs mentioned, this page shows a form with 2 inputs: Email and Code. This page will allow the user to enter their email and the code from the app to log in. Then, you redirect the user to the private page that you'll create later. You set the token in the session to a JWT created by the jwt library. If the check method returns true, it means that you can authenticate the user. This method takes the code as the first parameter and the secret as the second parameter. Then, the code is validated with the secret in the database using authenticator.check method. This function, first, retrieves the user by their email.

Start by creating a directory for our project and changing to it:Ĭonst express = require ( 'express' ) const sqlite3 = require ( 'sqlite3' ) const session = require ( 'express-session' ) const You need Node.js installed on your machine to be able to follow along with this tutorial. You can find the code for this tutorial in this GitHub repository. So, a lot of the necessary details related to 2FA, validation, and security might be omitted from the tutorial. This doesn't only work with Google's Authenticator, but also with Microsoft's Authenticator, or any other TOTP authentication apps.įor simplicity, this tutorial only focuses on authentication with the authenticator app. You'll create a simple website that requires users to enable authentication with an authenticator app when they register and then to enter the code every time they log in. In this tutorial, you'll learn how to implement this process in Node.js. If the code is correct, they're allowed to log in.

When the user needs to log in, they'll be asked to enter the code they see in the app. A 6-digit code will be shown and changed every 30 seconds. Then, the user can scan that QR code with their authenticator app.Īfter the user scans the QR code, they'll start getting time-based one-time passwords (TOTP) in the app.

What happens is that after your user registers or enables 2FA on their account, you generate a secret and create a QR code based on that secret. One form of 2FA is using authenticator apps like Google's Authenticator. Using 2FA, the user can rest at ease that just because someone has their password doesn't mean that they can access their account. 2-Factor Authentication (2FA) adds an extra level of security to your website or app.
