Software / scripts for Membership section , Login , Password control, on a website

[frankfriend]

Hi,
Can anyone share their experience of scripts, sources of scripts, or software to add a Members only section to a website. It must use secure passwords and user names, and log all entry attempts preferably with the IP address of the person trying to get into the site.

Best regards

I have copied this post to the Scripts etc Forum as I think I should have put it there not here, sorry,
