How to fix the issue to connect to SharePoint Online using PowerShell like below?
Because when I am using the PowerShell ISE, and then the command:
Connect-SPOService -Url 'https://CompanyName-admin.sharepoint.com'
I got the error:
Connect-SPOService : No valid OAuth 2.0 authentication session exists At line:1 char:1
Thank you.

MagicHappenZ 41 Reputation points2024-04-02T08:53:25.1566667+00:00 What are you trying to say?
"-UseWindowsPowerShell" parameter only works in a PowerShell 7 window where it won't find the module as its not part of $env:PSModulePath by default.
Furthermore not using the "-Credential" parameter does not make any difference as its still loading the old sign in mask without modern authentication support.

Anindya Kumar Banerjee 75 Reputation points2024-06-12T00:54:12.08+00:00 Strange! Windows PowerShell was for some reason unable to load the sign in page for modern authentication. Sometimes I will just see a blank window but no contents. The error is not thrown immediately but after several minutes.
I tried the above suggestion from @Jessie Sanchez in PowerShell 7 and voila! It worked like magic. @RaytheonXie_MSFT FYI.

RaytheonXie_MSFT 40,471 Reputation points Microsoft External Staff2023-02-20T07:47:09.0833333+00:00 Hi @EnterpriseArchitect ,
Per my test, we will get a windows to log in like following picture after call the cmdlet, and your browser doesn't support this function.
This error means you need to update your browser or download Edge as default browser. As a workaround, you can also use following cmdlet without log with a window. We can write the user account and secret into the cmdlet. Please make a reference
$username = "******@contoso.sharepoint.com" $password = "password" $cred = New-Object -TypeName System.Management.Automation.PSCredential -argumentlist $userName, $(convertto-securestring $Password -asplaintext -force) Connect-SPOService -Url https://contoso-admin.sharepoint.com -Credential $cred

Jo Hemmerlein 5 Reputation points Microsoft Employee2023-06-01T23:28:49.7766667+00:00 this isn't really viable when MFA or passwordless credentials are used.
