In PnP PowerShell for SharePoint 2013 site, how to give credentials only once, so that it will not ask credentials again while connecting to different site collections coming from a CSV file input.

Here is the code snippet:

```
$SiteCollections = import-csv -path ".\Source_Destination_URLMapping.csv"

$listTitle = "variation labels" 

foreach($SiteCollection in $SiteCollections) 
{ 
    Connect-PnPOnline -Url $SiteCollection.SiteUrl (get-pnplistitem -list "variation labels").count 
}

```
