Username and Password in VBS script to be used in VBA

Question

How can I pull my username and password from a vbs script and input that into my vba code. I manually input my username and password into the below, however I am worried others may find my login credentials.

VBA code:

    Public Property Let jiraUSER(Value As String):          pjiraUSER = "username"
                                                        End Property
Public Property Let jiraPW(Value As String):            pjiraPW = "password"
                                                        End Property

VBS:

'Input Excel File's Full Path
  ExcelFilePath = "O:\Export.xlsm"

'Input Module/Macro name within the Excel File
  MacroPath = "JIRARestAPIEngine.scriptGO"

'Create an instance of Excel
  Set ExcelApp = CreateObject("Excel.Application")

'Do you want this Excel instance to be visible?
  ExcelApp.Visible = True  'or "False"

'Prevent any App Launch Alerts (ie Update External Links)
  ExcelApp.DisplayAlerts = False

'Open Excel File
  Set wb = ExcelApp.Workbooks.Open(ExcelFilePath)

'Execute Macro Code
  ExcelApp.Run MacroPath

'Save Excel File (if applicable)
  wb.Save
 
'Reset Display Alerts Before Closing
  ExcelApp.DisplayAlerts = True

'Close Excel File
  wb.Close

'End instance of Excel
  ExcelApp.Quit

'Leaves an onscreen message!
  MsgBox "Your Automated Task successfully ran at " & TimeValue(Now), vbInformation

Thanks.
