React native module for Twilio Verify

About

Twilio Verify Push SDK helps you verify users by adding a low-friction, secure, cost-effective, "push verification" factor into your own mobile application. This fully managed API service allows you to seamlessly verify users in-app via a secure channel, without the risks, hassles or costs of One-Time Passcodes (OTPs). This project provides a library to implement Verify Push for your react native app.

Dependencies

React native 0.64.1

Installation

• Add the library to your project:

yarn add https://github.com/twilio/twilio-verify-for-react-native.git

• Install the pods for your project

npx pod-install

Enable push notifications

Register your iOS App with APNs

If you want to receive challenges as push notifications, you should register Your App with APNs.

More info here

Add firebase configuration for your Android App

If you want to receive challenges as push notifications, you should add a firebase configuration to your project

• Add a project in Firebase to use cloud messaging for an application ID
• Add the google-services.json file to your project

Add a push notification library

After setting up push notifications for Android & iOS, you should add a react native library to receive notifications from APN for iOS and FCM for Android.

The example app is using react-native-push-notification, you can find the full example source here

Usage

Create factor

import TwilioVerify, { PushFactorPayload } from '@twilio/twilio-verify-for-react-native';

let factor = await TwilioVerify.createFactor(
  new PushFactorPayload(
    factorName,
    verifyServiceSid,
    identity,
    accessToken,
    pushToken
  )
);

Verify factor

await TwilioVerify.verifyFactor(new VerifyPushFactorPayload(factor.sid));

Get challenge

let challenge = await TwilioVerify.getChallenge(challengeSid, factorSid);

Update challenge

await TwilioVerify.updateChallenge(
  new UpdatePushChallengePayload(factorSid, challengeSid, newStatus)
);

Get factors

let factors = await TwilioVerify.getAllFactors();

Get challenges

let challenges = await TwilioVerify.getAllChallenges(
  new ChallengeListPayload(factorSid, 10, ChallengeStatus.Pending, ChallengeListOrder.Desc)
);

Delete factor

await TwilioVerify.deleteFactor(factorSid);

Clear local storage

You can clear local storage calling the TwilioVerify.clearLocalStorage method:

await TwilioVerify.clearLocalStorage();

Note: Calling this method will not delete factors in Verify Push API, so you need to delete them from your backend to prevent invalid/deleted factors when getting factors for an identity.

Running the Sample app

Install the packages in the twilio-verify-for-react-native project

yarn install

Install the packages in the example app

cd example
yarn install

iOS

• Go to example and install the pods

cd example
npx pod-install

• Change the Bundle Identifier to something unique so Apple’s push notification server can direct pushes to this app

• Enable push notifications

• Get the Access token generation URL from your backend (Running the sample backend). You will use it for creating a factor

• Run iOS app in twilio-verify-for-react-native root folder

yarn example ios

Android

• Follow the steps from Firebase configuration, follow steps 1 to 3

  • For step 3.1, the google-services.json file should be copied to example/android/app
  • Google services plugin is included in the sample app, so you don't need step 3.2

• Get the Access Token generation URL from your backend (Running the Sample backend). You will use it for creating a factor

• Run Android app in twilio-verify-for-react-native root folder

yarn example android

Running the Sample backend

• Configure a Push Credential for the sample app, using the same Firebase project you configured for Android, and using the same APNs configuration for iOS
• Configure a Verify Service, using the Push Credential for the sample app (Android & iOS)
• Go to: https://www.twilio.com/code-exchange/verify-push-backend
• Use the Quick Deploy to Twilio option
  • You should log in to your Twilio account
  • Enter the Verify Service Sid you created above, you can find it here
  • Deploy the application
  • Press Go to live application
  • You will see your backend's start page, copy the url and replace index.html with access-token.(e.g. https://verify-push-backend-xxxxx.twil.io/access-token). This will be your Access Token generation URL

Using the sample app

Adding a factor

• Press Create factor in the factor list
• Enter the identity to use. This value should be an UUID that identifies the user to prevent PII information use
• Enter the Access token URL (Access token generation URL, including the path, e.g. https://verify-push-backend-xxxxx.twil.io/access-token)
• Press Create factor
• Copy the factor Sid

Sending a challenge

• Go to Create a push challenge section in your sample backend (https://verify-push-backend-xxxxx.twil.io/index.html)
• Enter the Identity you used in factor creation
• Enter the Factor Sid you added
• Enter a message. You will see the message in the push notification and in the challenge view
• Enter details to the challenge. You will see them in the challenge view. You can add more details using the Add more Details button
• Press Create challenge button
• You will receive a push notification showing the challenge message in your device.
• The app will show the challenge info below the factor information, in a Challenge section
• Approve or deny the challenge
• After the challenge is updated, you will see the challenge status in the backend's Create a push challenge section, as Login request approved! or Login request denied!, below the Create challenge button
