What is the meaning of this VBA code snippet from an Access form

Hi Experts,

Please refer to the below code, what does the 'If [n2] = [correct password] Then' line mean?

I can understand the rest but what are the two [n2] and [correct password] values reffering to?

If [n2] = [correct password] Then

   DoCmd.OpenForm "Employee", acNormal
   DoCmd.Close acForm, "LogInForm"

Else

   MsgBox("Password Error")

End If
