Access the server behavior from the Application panel, Server Behaviors -> + -> MX Kollection -> User Login -> Advanced -> Show Login Message.

The user is redirected to the login page, and given a message like the

and also for users who have just completed the forgot
password
page and have been returned to the login page.
