# Implementing your custom Passport app for iOS

Perform the following steps to implement your custom Passport App.

1. Verify that your development environment is set up correctly by successfully [building Passport app](/dpoa/docs/s3suite94-passportapp-customizethepasspoetappforios-building-passport-app-1).
2. [Configure your Authentication Server to work with Passport](/dpoa/docs/s3suite94-passportapp-customizethepasspoetappforios-configuring-passport-on-the-authentication-server-1). You should be able to register and authenticate with Passport. Follow the instructions in [Testing Passport App](/dpoa/docs/s3suite94-passportapp-customizethepasspoetappforios-testing-passport-app-1) to test your changes.
3. Now that you know your environment and Authentication Server configurations work correctly you can [implement your customizations](/dpoa/docs/s3suite94-passportapp-customizethepasspoetappforios-customizing-passport-1). This includes changing text and icons used as well as adding authenticators.
4. [Test your custom Passport App](/dpoa/docs/s3suite94-passportapp-customizethepasspoetappforios-testing-passport-app-1). Use Tutorial Web App and your Authentication Server to test that registration and authentication work.
