    What’s the difference? Was working with a co worker who has a Samsung S8 and I said to him this Face ID is flawless. He said “we’ve that’s nothing new”. He said we have face recognition and Iris scanner and Touch ID.

    Tell your coworker you can’t pass Face ID with a photograph.

    Face ID also does not need to scan irises or even see your eyes staring at it; indeed I can turn the attention required feature off and unlock without really focusing on the phone at all.

    Touch ID is completely unecessary with Face ID, IMO. Why have three things when one works so well?

    I have and S8+ and so does my husband. Over the course of owning our phones there was something about the iris scanner that started hurting our eyes very badly. There have been other MR forum members who concur. But plenty who have not had any problems. My last ophthalmology appointment did not reveal any eye damage.

    The Android implementation of face ID currently does not involve any form of 3 dimensional facial mapping. There is no ability to sense any depth, so it can be fooled by a high quality photograph. All matching is done only on two dimensions.

    This is not to bash Samsung phones, which we like very much. I’m just giving you a reply to your questions.

    Not the same tech. FaceID is a 3d map of your face. Iris scanning just looks at your eyes. Samsung also has a facial recognition option to unlock your phone but, even Samsung doesn’t consider it very secure.

    In my experience with Iris scanning it actually suffers from things that people like to wrongly complain about Face ID for. With Iris scanning you actually do have to have your eyes and phone lined up just right for it to unlock, as opposed to Face ID where you can glance at it from lots of different angles and don't have to line anything up.

    In the real world, I think FaceID is a bit faster and more consistent than Iris scanning on the Galaxy devices, but the difference is negligible. Yes, FaceID is more secure, but I’m willing to bet the average Joe is using biometrics as a convenient way to unlock their phone and not stash their nuclear launch codes.

    Side note: I’m amazed how many people still prefer to use the 4 digit PIN over TouchID/FPS. Different strokes for different folks I guess!

    Apple knows they invested in one primary security feature with Face ID, which they're confident enough to know they don't need three different security features to make a phone secure. Face ID and passcode back is all we need.

    Because one would like to have a back-up or fallback if FaceID fails and one would not like using the passcode, which would be nice

    That! And while we’re at it, why not use a 6digit or alphanumeric code?
    So many people are so lousy/relaxed/uncaring/uninterested with security. In the states there seems to be much more attention for things like identity fraud, over here (EU/Netherlands) even the police detectives don’t seem to take it serious.
    But a phone these days contains so much information about you. Where you have been, what you have bought, your bank account, your insurances, credit cards, birth date, pictures and everything.
