# Implementing Your Custom Passport App

Perform the following steps to implement your custom Passport App.

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