Getting started

Let's get started!

In this guide, you will learn how to integrate the Keyless SDK with your mobile application, which will enable your users to enroll and authenticate using the Keyless platform. Since Keyless has more advanced features than just a simple authentication product, the guide is split into multiple functional sections, each explained in more detail and with proper code snippets and examples for both the iOS and Android systems.

Prerequisites

Android
iOS
Android 6.0 (API level 23) and above
Gradle 6.5+
AndroidX
NOTE: to allow Keyless to handle the result of registerForActivityResult, you must call Keyless from an Activity implementing ActivityResultCaller. Your best option should be to extend any androidX activity that implements the interface for you, for example use the generic ComponentActivity or the more widespread AppCompatActivity
Install the following:
  • Xcode 10.1 or later
  • CocoaPods 1.4.0 or later
  • Make sure that your project meets the following requirements:
    • Your project must target iOS 12.4 or later.
    • Swift projects must use Swift 4.0 or later.
  • Set up a physical iOS device for running your app.
  • Enable Camera permissions: add the Privacy - Camera Usage Description key in your project’s Info.plist by adding the following (in XCode under Project > Info):
<key>NSCameraUsageDescription</key>
<string>Keyless needs access to your camera to enroll and authenticate you. Keyless cannot be used without your camera. Please allow camera permissions.</string>
  • Background processing. Enable the Background processing mode under Signing & Capabilities/Background Modes. Then, add the following in your project’s Info.plit (in XCode, under the key Permitted background task scheduler identifiers):
    <key>NSCameraUsageDescription</key>
    <key>BGTaskSchedulerPermittedIdentifiers</key>
    <array>
    <string>YOUR APP IDENTIFIER</string>
    </array>
If you use Progurad add the following rules:
# Keyless Proguard
-keep class io.keyless.sdk.** {*;}
-keepclassmembers class io.keyless.sdk.** {*;}

Installation

Android - Gradle
iOS - Cocoapods
Add the following within the repositories section of the settings.gradle file of your Android application. Replace the YOUR_CLOUDSMITH_TOKEN text with the CloudSmith token for partners provided to you by Keyless.
dependencyResolutionManagement {
repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
repositories {
google()
mavenCentral()
maven {
url "https://dl.cloudsmith.io/YOUR_CLOUDSMITH_TOKEN/keyless/partners/maven/"
}
}
}
Add the following to the dependencies block of your project build.gradle file, typically app/build.gradle.
app/build.gradle
dependencies {
// ...
implementation 'io.keyless:keyless-android-sdk:+'
}
Make sure you have the following options in the android block of the same file
app/build.gradle
android {
// ...
compileOptions {
sourceCompatibility JavaVersion.VERSION_1_8
targetCompatibility JavaVersion.VERSION_1_8
}
// add the following only if you're using Kotlin
kotlinOptions {
jvmTarget = "1.8"
}
}
Step 1: Create a Podfile if you don’t already have one
$ cd your-project-directory
$ pod init
Step 2: Setup Cocoapods to use your Cloudsmith credentials, by running the following commands and replacing YOUR_CLOUDSMITH_TOKEN with the Cloudsmith token for partners provided you by Keyless.
git config --global credential.helper store
echo "https://token:[email protected]" >> ~/.git-credentials
Step 3: Add the KeylessSDK pod to your Podfile
# This is the Keyless repository for partners
source 'https://dl.cloudsmith.io/basic/keyless/partners/cocoapods/index.git'
target 'MyApp' do
use_frameworks!
# Add the Keyless pod
pod 'KeylessSDK'
end
Step 4: Add the following at the bottom of the same file
post_install do |installer|
installer.pods_project.targets.each do |target|
target.build_configurations.each do |config|
config.build_settings['ENABLE_BITCODE'] = 'NO'
end
end
end
Step 5: Install the pods. If pod prompts you for authentication insert the string token as your username and then fill in YOUR_CLOUDSMITH_TOKEN as the password.
$ pod install
Analyzing dependencies
Cloning spec repo `cloudsmith-basic-keyless-partners-cocoapods-index` from `https://dl.cloudsmith.io/basic/keyless/partners/cocoapods/index.git`
Username for 'https://dl.cloudsmith.io': token
Password for 'https://dl.cloudsmith.io': YOUR_CLOUDSMITH_TOKEN

Configuration

Now all the dependencies should be set. To start using the Keyless SDK you just need to configure it.
Android
iOS
First initialize the Keyless SDK in your Application class:
// MainApplication
override fun onCreate() {
super.onCreate()
// Initialize Keyless
Keyless.initialize(this)
}
Make sure to add your application to you Manifest
<application
...
android:name=".MainApplication"
...
</application>
Then configure the Keyless SDK from your MainActivity, ViewModel or any class you use to communicate with Keyless.
Note: configure is asynchronous so wait for the completion callback before calling the next Keyless APIs
The configure method requires aSetupConfiguration as parameter. You should listen to the result as follows:
val setupConfiguration = SetupConfiguration.builder
.withApiKey("apiKey")
.withHosts(listOf("host:port))
.build()
Keyless.configure(setupConfiguration) { result ->
when (result) {
is Keyless.KeylessResult.Success -> {
Log.d("KeylessSDK", "configure success")
// Keyless is ready, you can now call
// enroll/authenticate/deEnroll ...
}
is Keyless.KeylessResult.Failure ->{
Log.d("KeylessSDK", "configure error")
// Inspect result.error for more info
}
}
}
All you need to do to configure the Keyless SDK, is to create an instance object of Keyless.Configuration and pass it to the Keyless.configure method, typically this in done in your app’s application(:didFinishLaunchingWithOptions: method:).
let configuration = Keyless.SetupConfiguration.builder
.withApiKey("apiKey")
.withHosts(["host:port"])
.build()
if let error = Keyless.configure(configuration: configuration) {
print("Keyless.Configure failed with error: \(error)")
}
