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.

    2024 and the module still does not support browser authentication making it pretty much useless to companies that use FIDO2 keys...

    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.

    User's image

    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 = "admin@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
