How to implement two-factor authentication in Bubble.io: Step-by-Step Guide

Implementing Two-Factor Authentication in Bubble.io for Enhanced Security

Implementing Two-Factor Authentication (2FA) in a Bubble.io application enhances security by requiring a second form of identification beyond just a password. This guide provides a comprehensive, step-by-step walkthrough to set up 2FA in Bubble.io using available plugins and custom workflows.

Prerequisites

• A working Bubble.io account with an app where you wish to implement 2FA.
• Basic understanding of Bubble.io, including workflows and plugin installation.
• Familiarity with authentication methods, including email and SMS verification processes.
• Access to email services or SMS providers to send verification codes.

Understanding Two-Factor Authentication

• Two-Factor Authentication (2FA) requires users to present two separate pieces of evidence to authenticate themselves.
• These factors typically include something the user knows (password) and something the user has (code sent via SMS or email).
• 2FA significantly boosts security by reducing the chances of unauthorized access.

Setting Up Two-Factor Authentication in Bubble.io

• Log in to your Bubble.io account and navigate to the application where you want to implement 2FA.
• Consider which form of 2FA you wish to implement: email-based, SMS-based, or an external authenticator app.

Implementing Email-based 2FA

• Ensure that your app is configured to send emails. You can use services like SendGrid for email functions.
• In your app's workflow, when a user logs in, generate a unique code for the session.
• Create a new data field for users to store the verification code temporarily.
• Use the "Send Email" action to send the generated code to the user's registered email address.
• Create a page or popup for the user to enter their received code, and validate this against the code stored in the database.
• If the code matches, log in the user; otherwise, prompt them to try again or request a new code.

Implementing SMS-based 2FA

• Choose an SMS provider that integrates well with Bubble.io, like Twilio.
• Install the required plugin for your chosen SMS service in your Bubble app.
• Set up an API workflow to communicate with the SMS provider to send verification codes.
• In the user login workflow, generate a unique verification code and store it in your database.
• Trigger the SMS API workflow to send the verification code to the user's phone number.
• Create an interface for the user to enter the SMS code, checking it against the database entry.
• On successful verification, complete the login process and clear the verification code field from the database.

Integrating Third-Party Authentication Apps

• Third-party apps like Google Authenticator enhance security with time-based codes.
• Use a plugin or API service that can generate and validate time-based one-time passwords (TOTP).
• During the user registration or security update, display a QR code that the user can scan with their authenticator app.
• Store the secret key for TOTP generation securely linked to the user's account.
• During login, prompt the user to enter the TOTP generated by their app and validate it using the stored secret key.
• Upon successful match, grant the user access; handle mismatches by allowing retries or alternate verifications.

Testing Your Two-Factor Authentication Setup

• Conduct a thorough test of the 2FA process within your application using test user accounts.
• Simulate different scenarios, including lost code incidents and incorrect code entries.
• Confirm that session handling and timeout policies are effective and that expired codes cannot be reused.
• Ensure that the user interface provides clear instructions and error messages throughout the 2FA process.

Deploying with 2FA Enabled

• After verifying the effectiveness and reliability of your 2FA implementation, proceed to deploy your application.
• Inform users about the new 2FA requirement and provide any necessary instructions or assistance for setting up their accounts.
• Monitor for any user feedback or issues related to 2FA, and be prepared to make adjustments as necessary.

Implementing Two-Factor Authentication in your Bubble.io app ensures enhanced security and user trust by reducing unauthorized access risks. By following this comprehensive guide, you can effectively integrate a robust 2FA system tailored to your specific application's needs.
