Create a text file named azureauth.json. Paste the JSON output from when you created the service principal.

Save this file in a secure location on your system where your code can read it. Use PowerShell to set an environment variable named AZURE_AUTH_LOCATION with the full path to the file, for example:

[Environment]::SetEnvironmentVariable("AZURE_AUTH_LOCATION", "C:\src\azureauth.json", "User")
