Is there a Coming Soon Page with password control

I’m in the process of building my wordpress site and I’ve got a Coming Soon page which works fine.
But it doesn’t let me allow certain individuals to view my site and give their opinions and suggestions. Is there a Coming Soon page out there that is password controlled and I can give certain people the password to gain access to the site? I don’t want to give them the username and password to my wordpress login cause they could then affect the site, I just want them to be able to view it and give their thoughts.
