Customizing authentication replacement messages
Customizing disclaimers or other authentication replacement messages involves changing the text of the disclaimer message, and possibly the overall appearance of the message.
Changing the disclaimer in System > Config > Replacement messages is not the same as selecting to customize a disclaimer used in a captive portal. The System > Config location is the default message that all disclaimers inherit. The captive portal location is a customized disclaimer that inherits the default format for the disclaimer message, but then can be customized for this portal.

3. Select the Edit icon. You can select and edit any of the pages. Change your text or layout as needed.
