Some users may want to restrict access to the login page for their event to only those users who can access it through a specific website or URL. To restrict access to the login page to a list of valid referrers, navigate to GENERAL SETTINGS and then scroll down to “Show Login Valid Referrers”:
Click on “Add a referrer” to add a new line and type in or copy-paste the URL formatted with http:// or https:// and in all lower case. Once you’ve added these lines, scroll down and click on “Submit” to save your changes.
Now that you have configured this feature, only attendees that reach the login page through the valid referrer will be able to access the login page. All other users will get an event login error message alerting them that the referrer they used is invalid. To customize this message, go to EVENT TOOLS > System Text Overrides and scroll down to the bottom of the Event Login grouping:
Click “Submit” to save your changes.
