Adding SIM Swap Detection to your Android Firebase Phone Auth projects

Requirements

• A tru.ID Account
• A Firebase Account
• A mobile phone with a SIM card and mobile data connection

Getting Started

Clone the repo:

git clone https://github.com/tru-ID/firebase-phone-auth-sim-swap-detection-android.git

Create a tru.ID Account

Install the tru.ID CLI via:

npm i -g @tru_id/cli

Input your tru.ID credentials which can be found within the tru.ID console

Install the tru.ID CLI development server plugin

Create a new tru.ID project within the root directory via:

tru projects:create firebase-android --project-dir .

Run the development server, pointing it to the directly containing the newly created project configuration. This will also open up a ngrok to your development server making it publicly accessible to the Internet so that your mobile phone can access it when only connected to mobile data.

tru server -t --project-dir .

Setting up Firebase for Android

This project uses Firebase Android. To set it up, head over to the official documentation

You will get a Ngrok URL in the form https://{subdomain}.{region}.ngrok.io.

Open the project up in your Android capable IDE, navigate to app/src/main/java/com/example/firebaseandroid/api/retrofit/RetrofitService.kt here and replace the value of base_url with the Ngrok URL.

Finally, connect your phone to your computer so it's used for running the Android project and run the application from your IDE.
