I have some code entered in to protect all the sheets upon close however I
would like to be able to unprotect them all by only entering the password
once as it is the same for all the sheets.

Thanks

Private Sub Workbook_BeforeClose(Cancel As Boolean)

Application.ScreenUpdating = False
Dim N As Single
For N = 1 To Sheets.Count
Sheets(N).Protect Password:="password"
Next N
Application.ScreenUpdating = True


End Sub
