Assume by "pages" you mean "worksheets".

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

Sub UnprotectAllSheets()
Application.ScreenUpdating = False
Dim N As Single
For N = 1 To Sheets.Count
Sheets(N).Unprotect Password:="justme"
Next N
Application.ScreenUpdating = True
End Sub

I can write a macro to protect lots of pages in a big workbook, but they are
protected without a password. How can I password protect them? I use Excel
