I am writing a script in PowerShell that is testing login credentials to a target SharePoint 2013 URL that are passed through to an Invoke-WebRequest command that calls the URL in question. When I use -UseDefaultCredential, the returned status is a 200, but when I replace that and try the following code passed in to a -Credential property of the same command, I get a 401 error:

[string][ValidateNotNullOrEmpty()] $userPassword = "password"
[SecureString] $userPassword = ConvertTo-SecureString -String $userPassword -AsPlainText -Force
[PSCredential] $userCredential = New-Object -TypeName 
System.Management.Automation.PSCredential("userName", $userPassword)
Invoke-Webrequest -Credential $userCredential -uri "https://connect.adler.edu" 
powershell -noexit

Any thoughts as to why I'm getting the 401 Error when using the -Credential property? Thank you!

Thanks, Neko, but still getting a 401 after amending my code after following your link... – Eric K. Jun 22 '20 at 20:41
