How to pass on credentials to windows security pop up for signing in

Basically there is a requirement, where i need to login to a web portal by passing on credentials through windows security pop up (like what we have to login for tomcat admin service console) & then click on a reload button on the next screen.

The script for clicking on the Reload button works fine but the problem is i have to manually login through the windows pop up & keep one active session open all the time & this is not possible when i want to add this script to a task scheduler.

The moment it tries to open http://localhost:9001/test/Admin/RuntimeParameters.jsp this is where it pops up with the windows security box & there is no way known to me to pass on the creds to this section. I need help for this piece.

	$ie = New-Object -com InternetExplorer.Application 
	start-sleep 4
	while($ie.ReadyState -ne 4) {start-sleep -m 100} 
	if ($? -eq "True")
		Write-host "Reload of the Admin page completed successfully" -ForegroundColor green
		Write-output "Reload of the Admin page completed successfully"
		Write-host "Reload of the Admin page Failed" -ForegroundColor red
		Write-output "Error: Reload of the Admin page Failed"

So i need help to know as how can we pass on credentials through PS script to login through a windows security pop up window not sure how PS can interact with this pop up window.

Thanks for checking & providing expert advise.

You can try to pass username and password in the URL.



Just make sure the username and password don’t include the following single characters

: @ /

The other alternative would be to use the Invoke-WebRequest cmdlet if you don’t need to display the page on a screen.

$creds = Get-Credential
$response = Invoke-WebRequest -UseBasicParsing -Uri http://localhost:9001/test/Admin/RuntimeParameters.jsp -Credential $creds
# do something with the response

Thanks Daniel for the response but it seems, current version of IE doesn’t support this method of passing on the creds through URL anymore :frowning:

Hi Daniel, instead of Invoke-WebRequest i tried this which allows to login & allows to fetch the web page code details instead of popping up the web page itself.

$url = "http://localhost:9001/test/Admin/RuntimeParameters.jsp"
$user = "username"
$pass = "pass"
$secPass = convertTo-secureString $pass -AsPlainText -Force
$cred = New-Object System.Management.Automation.PSCredential($user,$secPass)

$data = Invoke-RestMethod $url -Credential $cred

However, is there way to open the web page after it logs in like i had $url.visible=$true using $ie = New-Object -com InternetExplorer.Application & the navigating to this URL. I guess we cannot merge two invoke requests in the same method.

Please advise.

I can use both the invoke methods & assume am able to login fine but that’s all happening in the background.

The requirement is to click on a particular button on this web page after i am logged in into this webpage.

Tried both & get runtime error

$url = "http://localhost:9001/test/Admin/RuntimeParameters.jsp"
$user = "username"
$pass = "pass"
$secPass = convertTo-secureString $pass -AsPlainText -Force
$cred = New-Object System.Management.Automation.PSCredential($user,$secPass)

$response = Invoke-WebRequest -UseBasicParsing -Uri $url -Credential $cred

Write-host $response.StatusCode

Also tried -

$Link=$response.Document.getElementsByTagName("input") | where-object {$_.type -eq "submit"}

I am trying to click The actual button from the html code from the web page is

form action = "#" method="POST"
input type="submit" value="Reload" name="Reload"

Thanks for the update. I think you’ll need to look at Selenium which is web browser automation framework ( and it is free as far as I know.

Have you tried

Get-Credential | Export-Clixml -Path 

This will bring up the UN/PW windows dialogue box. When you enter your credentials, this will write the UN and PW to an encrypted text file (as stipulated by your given path). For instance

Get-Credential | Export-Clixml -Path C:\Cred\EncryptedCredentials.txt

You can then add the content of this file to a variable in your script.

$MyCredential = Import-Clixml -Path C:\Cred\EncryptedCredentials.txt

Which can later be refeferenced by a -credentials parameter in your script.

This works fine for me when running scripts that need to authenticate against an externeal FTP server.

Caveat: The acount you are logged in within when you create the encrypted credentials will need to be the same account you want to run the scripts under.

*need to run the scripts under.
