Was this ever answered? I have the same problem in that I have set it so that when my Members Only Page is selected from the main menu, the screen jumps to a WIX generated screen labelled “Guest Area” with a password “line” to be populated. So, how do I set up a toggle for password visibility on this WIX generated (I appear to have no access to this) screen?
The Password Protected page is a “system page” and isn’t accessible via the edit. It’s not currently possible to change it’s functionality.
