to the following syntax what can be added so that I can put a password (2468)
on the protection of the sheet. Right now, this sheet automatically protects
itself and I want to add a password. Can a macro automatically enter a
password (2468) upon its protection of the sheet?

Option Explicit

Private Sub worksheet_change(ByVal target As Range)
Dim rngDV As Range
Dim oldVal As String
Dim newVal As String
If target.Count 1 Then GoTo exitHandler

On Error Resume Next
Set rngDV = Cells.SpecialCells(xlCellTypeAllValidation)
On Error GoTo exitHandler

If rngDV Is Nothing Then GoTo exitHandler

If Intersect(target, rngDV) Is Nothing Then
'do nothing
Else
Application.EnableEvents = False
newVal = target.Value
Application.Undo
oldVal = target.Value
target.Value = newVal
If target.Column = 11 Then
If oldVal = "" Then
'do nothing
Else
If newVal = "" Then
'do nothing
Else
target.Value = oldVal _
& ", " & newVal
End If
End If
End If
End If

exitHandler:
Application.EnableEvents = True

If target.Cells.Count 1 Then Exit Sub
If target.Row < 10 Or target.Row 13 Then Exit Sub
Application.EnableEvents = False
If target.Column = 2 Then
If IsNumeric(target) = False Then
If Len(target) 0 Then
target.Offset(0, 4) = ""
End If
End If
End If
Application.EnableEvents = True
End Sub

Thank You
