Difference between PowerShell cmdlets Open-PWConnection and New-PWLogin

Can somebody explain any differences between Open-PWConnection and New-PWLogin and when you would use one over the other?

It looks like Open-PWConnection has an -admin option and New-PWLogin doesn't.  Wouldn't you always want to use -admin?

  • Here's what I have from my notes regarding New-PWLogin

        #-verbose option displays if working dir exist and what datasource connecting to
        #Forced to administration mode - no non-admin mode
        #Checks for a working dir and if it doesn't exist it creates it without prompting
        #With no parameters GUI is assumed
        #If password is not provided SSO is assumed
        #If username is not provided SSO is assumed
