# Getting started with the Passport App for Android

## Overview

> To fully understand the information presented here, **we strongly urge you** to first read *Start* [Out-of-band integration](/dpoa/docs/s3suite94-integration-with-out-of-band-1) and [Out-of-band Authentication](/dpoa/docs/s3suite94-android-implementing-authentication-in-your-app-1#outofband-authentication) in the *Android Developer Guide*.

Passport App for Android 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 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 [*Web Developer Guide*](/dpoa/docs/s3suite94-web-developer-guide-for-web-1).

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 the [*Using Passport App for Credential Sharing*](/dpoa/docs/s3suite94-configuring-tutorial-app-1#using-passport-app-for-credential-sharing) in the *Android Developer Guide*.
