I have been struggling with "the password" feature. It was working fine when it was in the development stages, then when we went "live", it would not accept the password we gave it. As instructed by James of the "Page Lines Experience Team", I deactivated all the plug ins, changed the pass word, and then "saved" the permalinks. I even changed the passowrd on every page where it appears to a new one, but it still doesn't work. I do not think this is a plu-in, as it is part of the bulit in password "Visibility" feature on the Dashboard/Pages. Attached is a screen shot of the Plug-ins I have, now, all deactivated.
