# Configure a FIDO2 Authentication Method

## Introduction

To configure the Nok Nok S3 Authentication Suite to support FIDO2:

1. [Determine your RP ID](/dpoa/docs/s3suite94-determining-an-rp-id).
2. [Authenticate with the user name](/dpoa/docs/s3suite94-authenticating-with-the-user-name). Or [configure your proxy](/dpoa/docs/s3suite94-alternate-step-configuring-your-proxy), if you implemented a replacement for the API Server.
3. For native Android apps, create a digital asset links file so your apps work with FIDO2. For more information, see [Creating Your Digital Asset Links](/dpoa/docs/s3suite94-creating-your-digital-asset-links-file) File. For native iOS apps, list your app in your associated domain file: apple-app-site-association. See [Apple's documentation on supporting associated domains](https://developer.apple.com/documentation/xcode/supporting-associated-domains) for more information.
4. [Configure the FIDO2 authenticators to use](/dpoa/docs/s3suite94-configure-fido2-authenticators).
5. Configure your FIDO2 apps. For more information, see [Configure Apps](/dpoa/docs/s3suite94-configure-apps).
