You can use a custom app built using the Guardian SDKs for iOS or Android that relies on vendor-specific push notification services.

1. Create an SNS Platform Application using AWS Management console and note it’s ARN.

2. Create an AWS Access Key ID authorized to create Platform Application endpoints. Guardian automatically creates a Platform Application endpoint with an appropriate device token as part of a successful enrollment.

To receive push notifications from Guardian, it's necessary to override Guardian's default SNS settings.

1. Go to Dashboard > Security > Multi-factor Auth and click on Push via Auth0 Guardian. Click the toggle if it is not yet enabled.

2. Click the down-arrow next to Use a Custom App. The settings page expands.

3. Under Amazon SNS Configuration, enter your AWS Access Key ID and ARN from the AWS Management Console.
