32. Evaluation Results – Help Manual authenticateuser This is important logic for ensuring that a user is registered with the intervention and is usually found after the login page. The authenticateuser command can be used in the logic (intervention.lgil) file or in the error message logic. Example after login if (authenticateuser (login.username, login.password)) goto page1 So in the example above the details that the end-user enters into username and password interactions on the login page will be used to check that they are a registered user.
