Dean, here is some code that will do it, don't remember where it came from,
password set to 123

Private Sub Worksheet_Activate()
Dim strPassword As String
On Error Resume Next
Me.Protect Password:="123"
Me.Columns.Hidden = True

strPassword = InputBox("Enter password to view this sheet", "Password
required !")

If strPassword = "" Then
Me.Previous.Select
Exit Sub
ElseIf strPassword < "123" Then
MsgBox "Password Incorrect", , "Wrong password"
Me.Previous.Select
Exit Sub
Else
Me.Unprotect Password:="123"
Me.Columns.Hidden = False
End If

On Error GoTo 0
End Sub

Private Sub Worksheet_Deactivate()
On Error Resume Next
Me.Columns.Hidden = True
On Error GoTo 0
End Sub

To put in this macro right click on the worksheet tab and view code, in the
window that opens paste this code, press Alt and Q to close this window and
go back to your workbook. If you are using excel 2000 or newer you may have
to change the macro security settings to get the macro to run. To change the
security settings go to tools, macro, security, security level and set it to
medium

To change the security settings go to tools, macro, security, security level
and set it to medium

You will also need to password protect your VBA project so no one can see
the password there

To protect the VBA project, from your workbook right-click the workbook's
icon and pick View Code. This icon is to the left of the "File" menu this
will open the VBA editor, in Project Explorer right click on your workbook
name, if you don't see it press CTRL + r to open the Project Explorer then
select VBA project properties, protection, check lock project for viewing
and set a password. Press Alt and Q to close this window and go back to your
workbook and save and close the file. Be aware that this password can be
broken by third party software

Is it possible to password protect a sheet in Excel so that if a user
clicks
the Tab they are asked for the password before the screen is displayed?

VBA coding could be a possability?

Thanks Dean
