I have the following to ask the user to log in to show their specific
worksheet in a workbook and hide the rest. This is activated when they click
the OK button in a form that pops up when Excel opens:

bOK2Use = False
bError = True
If Len(txtUser.Text) 0 And Len(txtPass.Text) 0 Then
bError = False
Select Case txtUser.Text
Case "userMe"
sSName = "Me"
If txtPass.Text < "nascar05" Then bError = True
Case "weng"
sSName = "Mine"
If txtPass.Text < "nascar07" Then bError = True
Case Else
bError = True
End Select
End If
If bError Then
MsgBox "Invalid User Name or Password"
Else
'Set document property
bSetIt = False
For Each p In ActiveWorkbook.CustomDocumentProperties
If p.Name = "auth" Then
p.Value = sSName
bSetIt = True
Exit For
End If
Next p
If Not bSetIt Then
ActiveWorkbook.CustomDocumentProperties.Add _
Name:="auth", LinkToContent:=False, _
Type:=msoPropertyTypeString, Value:=sSName
End If

Sheets(sSName).Visible = True
Sheets(sSName).Unprotect (txtPass.Text)
Sheets(sSName).Activate

bOK2Use = True
Unload UserForm1
End If

My question is, how can I modify this so that a manager can log in and see
ALL worksheets, i.e., unhide all worksheets, without getting the "you're not
authorized to view" message? Any help is greatly appreciated. Thank you!!
