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. IPWorksAuth.Hotp hotp = new IPWorksAuth.2-Factor Authentication (2FA) adds an extra level of security to your website or app. IPWorksAuth.Totp totp = new IPWorksAuth.Totp() Private void sftp1_OnSSHKeyboardInteractive(object sender, SftpSSHKeyboardInteractiveEventArgs e) Within this event the HOTP and TOTP components can be used to retrieve the one time code necessary for authentication. From within this event the Prompt parameter can be inspected to determine the information requested by the server, and the response is sent back by setting the Response parameter. When this happens the SSHKeyboardInteractive event will fire. Sftp1.SSHAuthMode = ĭuring authentication the server will prompt the user for authentication. Within the keyboard-interactive event of the SSH components the HOTP or TOTP component from IPWorks Auth can be used to retrieve the one time code.Īfter creating the component instance set the SSHAuthMode property to keyboard-interactive. The IPWorks SSH Sftp component, when used in conjunction with IPWorks Auth HOTP or TOTP components, allows for two-factor authentication. In that case when connecting a user will be prompted to enter the one time code in addition to the standard credentials. SSH servers may be configured to require TOTP or HOTP based two-factor authentication using libraries like libpam-google-authenticator.
