When you're setting up an access code on one of your Builder's pages, you have the option to add an access code message, which will appear to the right of the access code field. If you leave this field blank, the default message will be "Please enter your access code to view this page." If you'd like to set up your own default access code message, you can do so in your Builder's settings.
First, click on the Builder icon and hover over settings, then click on general.
Under Access Code Message, enter the message you'd like to appear next to the access code field then click on save changes.
