How secure is VeriFace facial recognition software?

I use VeriFace to log onto my Lenovo laptop by default. It is quick and logs me in easily, but I have to wonder how secure it really is. Would some other brown haired, blue-eyed guy in his 30s fool the software on my laptop, for example? I’m a big fan of making things easier for myself, but I do need a modicum of security too.
