Techno's dashboard

For the Yola password protect feature on a web-page can you add more than ONE username and password?

on my website sometimes when I go onto my home page (not in yola-site builder) it is not there. I have pressed the update button lots!!. Also when i am in the site builder on my home page editing it, if i click on another tab in the menu to edit it then go back to my home page, my home page has gone i just have a blank page and i do click YES when it ask you to save.
