OneDrive PowerShell Module – New Version with Improved Authentication

A few months ago, I wrote a PowerShell module to access OneDrive. I got a lot of feedback from the community – thanks for that.

This week I published a newer version to PowerShellGallery.com including new features and bugfixes. These are the main improvements:

Bug fixes:

• Filename and paths containing special characters like ‘=’, ‘$’, etc. are now handled correctly
• Enumeration of folders with a file count >200 is now working

Improvements:

• Get-ODAuthentication now supports a “code” based-authentication including refresh of the authentication with a refresh token. This allows an unattended run of long running scripts.

How to log on to OneDrive using a code based authentication?

Hint: There is also a video on youtube showing this example: https://www.youtube.com/watch?v=yZNt0RT5wQs

Register your app/script for OneDrive

First, register your app/script at the Application Registration Portal:

• Go to: https://apps.dev.microsoft.com and login with your Microsoft Account (MSA)
• “Add an app” in the category “converged applications”:
  
• Enter a name and press “create”
  
• Press “Generate New Password“ and save the password (app key)

• Also save the “Application id”
• Press “Add Platforms” and select “Web”

• Check “Allow implicit Flow” and enter a “Redirect URL”. This is not a real URL. Choose a localhost address and note it. In my case I chose: http://localhost/login  
• Press “Save”

Now you have all necessary data for your app / script:

• Client Id: 5dd40b03-0ead-451b-b5e3-f704550e8cca
• AppKey: xqacs8K92MuCJKgciRHQ1Cf
• RedirectURI: http://localhost/login

Get an authentication token

To get an authentication token use:

Hint: Use “-AutoAccept” to avoid the confirmation windows

Test the authentication token

Save the authentication token to an object:

List files in a OneDrive-folder:

Renew the authentication token

An authentication token is valid for an hour. You can get a new “code” based token with the “refresh_token” from the login before:

Install the new version of OneDrive from PowerShellGallery.com

If you have the module PowerShellGet to access PowerShellGallery already installed, you can easily download this module with a single command (“-force” updates the module to the newest version):

You can update the module to a newer version with the same command (add -force). If you don’t use PowerShellGet currently, go to the Gallery on https://www.powershellgallery.com/packages/OneDrive and click on “Get Started”.
