# Getting started with the Passport App for iOS

## Overview

> To fully understand the information presented here, **we strongly urge you** to first read *Start* [Integration with out-of-band](/dpoa/docs/dpo-integration-with-out-of-band) and [Out-of-band authentication](/dpoa/docs/dpo-ios-app-sdk-implement#out-of-band-authentication) in the *iOS Developer Guide*

Passport App for iOS allows you to use out-of-band (OOB) authentication without incurring the overhead of implementing OOB support in your own mobile app. OOB authentication enables you to use a second device tied to the user, typically their cell phone, to authenticate. Your web app initiates authentication by either:

- Sending a push notification to your customized Passport App that is installed on the user's cell phone. When the user receives the notification, they authenticate with your customized Passport App using a registered FIDO authenticator, like fingerprint.
- Displaying a QR code on the device running your web app. The user scans the QR code with your customized Passport App, then authenticates with a registered FIDO authenticator.

To implement your web app, see the [Developer guide for web](/dpoa/docs/dpo-web-app-developer-guide).

Passport App can also be used to enable credential sharing between one or more of your apps. To try this out using Tutorial App, see [Using keychain sharing](/dpoa/docs/dpo-tutorial-app-for-ios-configuration#using-keychain-sharing).
