each member needs a unique password

hi. i have a site where there’s a page i want to make private and only accessible to memebers. however i need to give out a unique password for each member because if it’s just one password that everyone uses to login, they could send that around and privacy goes out the window.

what’s the best way to go about this? it seems that when i use the password protect feature for a specific page, it only creates one password that everyone would use.

please advise. thanks!
