Additionally, the guide talks through the following steps to configure and implement.

Example of React Native + Amplify (Sign in with passkeys)

import {Auth} from 'aws-amplify';
import {authsignal} from '../config';
...

let cognitoUser: any;

const onPressSignIn = async () => {
  cognitoUser = await Auth.signIn(userName);
  
  const {token} = cognitoUser.challengeParam;
  
  const {data} = await authsignal.passkey.signIn({token});
  
  await Auth.sendCustomChallengeAnswer(cognitoUser, data);
};

And that's it.

It's that simple with the Authsignal SDKs and guides to get passkeys supported with AWS Cognito and Amplify, the same flows can also be achieved with web browser flows, and we'd cover this in future blog posts.
