Macro Code

Hey all..
I've got this code protecting my macro button. It works but bypasses and runs through and resets my excel sheet what the macro was built to do. In the case of an incorrect password it should end but doesn't.

Where did I go wrong? Help is much appreciated..

Private Sub CommandButton1_Click()
Dim password As Variant
password = Application.InputBox("Enter Password", "Password Protected")

Select Case password
    Case Is = False
        'do nothing
    Case Is = "reset"
        Range("A3").Value = "This is secret code"
    Case Else
        MsgBox "Incorrect Password"
End Select
