As yet, this component isn't as well rounded as some others available, but it is getting better all the time. The more people who use it and give feedback the better it will become.
Unfortunately the documentation for this extension isn't great, but I’ve noticed they’ve improved it recently though.
HsUsers is easy to install, it’s free, there is no middleman and there is no monthly fee.
The most important thing for me is that there is no middleman. There is absolutely no need for a middleman and it is undesirable to have one. The middleman has access to your valuable website data and charges you a fee for it! Furthermore, I think you will find that if the middleman has technical problems your users will be unable to log in to your website.
I had trouble getting this extension to work at first, but that was due a stupid mistake on my part. If you like to edit the html without a WYSIWYG editor then check this one out!
