To promote this as security is laughable. I installed it and rebooted my computer. The only thing this software did was to make my OS horribly slow to boot up and to remove my password. When I booted it up I just gained access to my OS immediately - no password and no facial recognition required.
I wondered if it had just happened too fast for me to notice, so I booted my computer up while pointing the cam at my younger sister. Again, after the long load, it accessed the OS immediately. Just to make sure that the program didn't just think my sister and I are sufficiently similar, I then rebooted my computer while pointing the cam at an empty armchair. Apparently my sister and I look a lot like empty armchairs because that also gained me access to the computer.
So don't bother installing this. Just remover you password instead. It's a lot easier and it has the same result except that you don't have to wait for it to load.
