Membership site able to detect shared passwords

Hello BHW,

I am needing a simple membership site, or form login with admin panel. My site is free, but has content I don't want found or shared. Right now I have the area protected with Basic Auth through htaccess. Basically its a training site, and my downline members will be given the link. From there they either create a free account, or login if they already created one.

I would like a script that will block brute force attempts (IE - freeze the account for x hours, or prevent that IP from trying again for x hours)

But most importantly, I am needing to keep track of the users. I MUST know if they are sharing the password. Kind of like porn sites do, if there has been too many logins from more than x amount of IPs, it will freeze/suspend the account.

Any ideas of what script will do this?

I guess nobody knows of a secure account management software?? It just needs to help be suspend shared accounts, and protect against brute force attempts.

A script called stopthathacker comes to mind. Never used it but I remember the name. I just checked the site and the copyright is 1998-2003 so it may not have been updated in awhile..... use this as a starting point of research perhaps.

search for a script called pennywize or strongbox
a lot of adult sites use those on their members area
