Here is all my script. In this moment all works very well , just I want to add 2 users for auth. If 1 fail try other one. Any ideea ? Thank you

I couldn't test this myself, but I think I would go about it like below:

$User         = "SameUser"
$Password     = "Pass1"
$sPassword    = "Pass2"
$Command      = "C:\Info.exe"
$secpasswd    = ConvertTo-SecureString $Password -AsPlainText -Force
$ssecpasswd   = ConvertTo-SecureString $sPassword -AsPlainText -Force

catch {
