React Native module for Transmit Security Authentication SDK
npm install react-native-ts-authenticationAdd strong authentication with Passkeys to your native iOS and Android applications, while providing a native experience. This describes how to use the React Native module to register credentials and use them to authenticate your users.
This SDK provides a unified solution for implementing both Apple's public-private key authentication for passkeys on iOS and Google's Credential Manager API for passkeys on Android. It enables the integration of FIDO2-based biometric authentication seamlessly into your mobile applications, offering users a native experience instead of a browser-based one. With passkeys, credentials are securely stored by the device, leveraging iCloud Keychain on iOS and Google Password Manager on Android. These credentials are associated with your domain, facilitating secure sharing between your mobile app and website if applicable.
Using this module, you can easily integrate our Authentication SDK into your React Native app for seamless and secure user identity authentication.
Learn more about how you can boost your security with Transmit Security Authentication.
1. From the Applications page, create a new application or use an existing one.
2. From the application settings:
* For Client type , select native
* For Redirect URI , enter your website URL. This is a mandatory field, but it isn't used for this flow.
* Obtain your client ID and secret for API calls, which are autogenerated upon app creation.
* Enable public sign-up if you manage users using an external system (e.g., external identity provider) or if you want to quickly test WebAuthn registration and authentication without first logging in using a different authentication method.
3. Refer to our iOS and Android documentation mentioned above to configure an auth method and associate your domain for Apple and Google.
1. In your project, navigate to example/src/config.ts and configure the clientId, domain, secret and baseUrl using the configuration obtained from the Transmit portal.
2. Ensure you have all the necessary dependencies by running yarn in both the module's root folder and the example root folder.
3. Run the example app on a real device using Xcode or Android Studio. Alternatively, execute yarn example ios or yarn example android.
> Important Security Note: Never store your secret in a front-end application.
>
> The example app utilizes a mock server to manage communication with the authentication platform. This mock server employs the secret you have specified in example/src/config.ts exclusively for demonstration purposes. It is paramount that you safeguard your secret in a secure and confidential location.
``sh`
npm install react-native-ts-authentication
in your project's /ios folder and set your minimum iOS target to 15.0 in your Podfile (e.g platform :ios, 15.0).* Add project Capabilities as described iOS quick start
* Update YOUR Bundle ID and setup associated domains as described in the iOS quick start

#### Note:
As for projects on Gradle 8+ and Kotlin 1.8+ build will fail if the JDK version between compileKotlin and compileJava and jvmTarget are not aligned.
This won't be necessary anymore from React Native 0.73. More on this: https://kotlinlang.org/docs/whatsnew18.html#obligatory-check-for-jvm-targets-of-related-kotlin-and-java-compile-tasksUsage

#### iOS
1. Open your project's
.xcworkspace found under YOUR_PROJECT_PATH/iOS in Xcode.
2. Create a plist file named TransmitSecurity.plist in your Application with the following content. CLIENT_ID is configured in your Transmit server. Make sure the file is linked to your target.`xml
credentials
baseUrl
https://api.transmitsecurity.io
clientId
CLIENT_ID
`
#### Android
1. Open your Android manifest XML file, usually located at android/app/src/main.
2. Update the strings.xml file in your Application with the following content. The CLIENT_ID should be replaced with your client ID`xml
"default_application"
"CLIENT_ID"
https://api.transmitsecurity.io

Instead of using Plist and strings.xml, you can initialize the module with parameters:

2. Custom Domain - Can be null (or undefined if not using BaseURL)
