I have been using invision for a long time and have shared many urls with my clients. However, these urls have not been password protected but I need my prototypes to be private, because I have realized that when I enter a shared url without logging into invision all the prototypes can be seen by anyone. I need to protect them with a password but without changing the URL that I already shared with my clients because they are links from more than two years ago that I would have to update one by one.
Is there a way to change the whole prototype to private without having to do it for each URL?
I hope you can help me.
