I was going to use osTicket as my 'help desk' for my website, however I just got a little bit concerned when I realised that the clients' login details to see their support tickets are only their email address and a ticket ID. I am probably going over the top with security though, which is why I wanted to get some second opinions on how secure osTicket actually is and whether I should use it with my website. I run a software company, so chances are licence keys may be included in support tickets which are obviously sensitive information and valuable - so I want to ensure that the likelihood of a support ticket being hacked is very low.

If there is any plugins/additions to make osTicket more 'secure', I would appreciate it if you could point me to them. Otherwise if there are any more free, more suited, help desk softwares out there please let me know.

Thanks in advance
