You can read more about how passkeys work in the [Android developer docs](https://developer.android.com/design/ui/mobile/guides/patterns/passkeys).

<Callout warning>
Registering a passkey is supported on Android 9 (API level 28) and above.
</Callout>

Using passkeys with Amplify requires following these steps:

1. Deploy a Digital Asset Links file to your website granting the `get_login_creds` permission to your application. See the [Credential Manager documentation](https://developer.android.com/identity/sign-in/credential-manager#add-support-dal) for more details about this file.
1. [Configure your Amazon Cognito user pool](/[platform]/build-a-backend/auth/modify-resources-with-cdk/#override-cognito-userpool-to-enable-passwordless-sign-in-methods) with `WEB_AUTHN` as an allowed first factor, and specify your website domain as the `WebAuthnRelyingPartyID`.
1. Use the Amplify Android APIs to first [register a passkey](/[platform]/build-a-backend/auth/manage-users/manage-webauthn-credentials/#associate-webauthn-credentials) and then to [sign in with WebAuthn](/[platform]/build-a-backend/auth/connect-your-frontend/sign-in/#webauthn-passkeys).

### Managing credentials

{/* quick blurb then segue over to "manage WebAuthn credentials" page */}
Passwordless authentication with WebAuthn requires associating one or more credentials with the user's Amazon Cognito account. Amplify provides APIs that integrate with each platform's local authenticator to easily create, view, and delete these credential associations.
