This was exactly the example I submit when the Year of Code topic was Web.

A commonly needed feature for Web Apps is auto-login. In 2013, Greg wrote about secure login screens on the Blog. This was later adapted into a documentation page, but not updated. For this month’s project, I have created an example that shows how auto-login can be implemented without storing user credentials.

WebPageLogin Opening Event

Sub Opening() Handles Opening
  System.DebugLog CurrentMethodName
  
  #If DebugBuild Then
    TextFieldKey.Text = App.Key
  #Else
    TextFieldKey.Text = Session.Cookies.Value("Key")
  #EndIf
   
End Sub

Ok Button Pressed Event

Sub Pressed() Handles Pressed
  If TextFieldKey.Text.Compare(App.Key, ComparisonOptions.CaseSensitive) = 0 Then
    
    Session.Cookies.Set("Key", TextFieldKey.Text, DateTime.Now + New DateInterval(0,0,7), "", "", True)
    
    Self.Close
    Session.LoggedIn = True
    WebPageStart.Show
    
  Else
    'Wrong
    Attempts = Attempts + 1
    If Attempts> 3 Then
      Me.Enabled = False
      TextFieldKey.Enabled = False
    End If
  End If
  
End Sub
