FlutterFlow and Duo Security integration: Step-by-Step Guide 2024

     

• Create an Account: If you do not already have a Duo Security account, visit Duo Security and sign up for an account.
• Log In: Log into the Duo Admin Panel using your new credentials.
• Set Up Android/iOS: Under the 'Applications' section, select 'Protect an Application' and search for the proper integration SDK, based on whether you're targeting Android, iOS, or both.

   

• Download Duo Mobile: Ensure you have the Duo Mobile app installed on your smartphone. This app will be used for generating the authentication codes and pushing login notifications.

   

• Application Integration Key: Note down the Integration Key (ikey), Secret Key (skey), and API Hostname. You will need these when you integrate Duo Security with FlutterFlow.

   

• Create a Project: Open FlutterFlow and create a new project or open an existing one.
• Add Dependencies: Add the necessary dependencies for using Duo Security’s SDK and APIs. For instance, if using HTTP requests, you would add the http package to your pubspec.yaml file.

dependencies:
  flutter:
    sdk: flutter
  http: ^0.14.0

   

• Import Packages: Within your FlutterFlow project, import the necessary packages in your Dart files.

import 'package:http/http.dart' as http;
import 'dart:convert';

• Create API Services: Write Dart services or utility methods to create HTTP calls to Duo Security’s API.

class DuoService {
  final String ikey = 'Your_Integration_Key';
  final String skey = 'Your_Secret_Key';
  final String apiHostname = 'Your_API_Hostname';

  Future initiateAuth(String username) async {
    final uri = Uri.https(apiHostname, '/auth/v2/auth', {
      'user': username,
      'device': 'auto',
      'factor': 'push'
    });

    final response = await http.post(uri, headers: {
      'Content-Type': 'application/x-www-form-urlencoded',
      'Authorization': 'Basic ' + base64Encode(utf8.encode('$ikey:$skey'))
    });

    if (response.statusCode == 200) {
      var result = json.decode(response.body);
      // Handle success response
    } else {
      // Handle error response
    }
  }

  // Additional functions for verification, and other tasks
}

   

• Design Login Screen: Design your login screen using FlutterFlow’s widgets.
• Add Authentication Logic: Link your UI components to actions that call DuoService methods. For example, on a button press, initiate Duo authentication.

onPressed: () async {
  DuoService duoService = DuoService();
  await duoService.initiateAuth('test\_username');
  // Process the response and navigate accordingly
};

   

• Run Flutter App: Now run your FlutterFlow app and test the integration.
• Monitor Duo Dashboard: Track and monitor the authentication requests from the Duo Admin Panel to ensure everything is operating correctly.

   

• Loading Indicators: Add appropriate loading indicators and user messages during the authentication process.
• Error Handling: Ensure you handle errors gracefully, providing user feedback when authentication fails.

try {
  await duoService.initiateAuth('test\_username');
  // Navigate to the next screen or show success message
} catch (error) {
  // Show error message
  print(error);
}

   

• Secure Storage: Store sensitive keys securely, possibly using a secure storage mechanism like flutter_secure_storage.
• Code Review: Regularly review your code for vulnerabilities and follow security best practices.

   

You’ve successfully integrated Duo Security with FlutterFlow. This integration ensures that your application can utilize two-factor authentication, enhancing its security. Always keep security keys private and perform frequent security audits of your application.
