Introduction

This article shows how to impersonate a service account from user account credentials. To understand how to set up everything, read the companion article:

Save the following PowerShell script as a file named impersonate_service_account.ps1. This has been tested on Windows 10 with PowerShell 5.1 and PowerShell 7.0

This example implements a web server for Google OAuth 2 user authentication. The user’s credentials are saved to a file, and the credentials are reused. A good example of saving the OAuth Refresh Token to recreate access tokens. Once the user access token is created, a service account is impersonated the new access token is used to display Compute Engine instances.

I plan to release this code on GitHub to make access easier. Watch for an update with more examples in C#, Python, Go and PowerShell.
