I just bought a 950 XL and i was thinking about this today. From a security standpoint Windows Hello on the 950 and 950 XL does nothing. Sure it looks cool and it's a novelty feature but if MS is trying to sell Hello as a more secure feature i don't see the reason. It is there in ADDITION to the pin, so if someone is trying to break into your phone or finds out your pin then they can still unlock the phone with or without Hello. I thought Hello would be enabled in place of a Pin then it would make sense. But when i went to enable Hello on my 950 XL it said i must have a pin on my phone then i could set it up and enable it. What's the point of a super secure Iris scanner if it is just an addition to insecure 4-digit pin. I guess in the future it may function differently and thats why its just in beta but as it is...i really dont understand this security feature. Anyone want to chime in here? Or prove me wrong that would be fine too ...just trying to make sense of this.
