    People usually sleep near their phones. Couldn't someone just use your hand while you're asleep to unlock your phone?

    They should add some features that prevent this. Like, your face has to be recognized by iSight camera with your eyes open also. Or, you can set fingerprint unlock to require a passcode between the hours of X and Y, or whenever you have Do Not Disturb activated.

    Obviously you could restart your phone every night before bed then lock it, but that seems draconian.

    If your sleeping with someone who you don't trust to access your phone then you have bigger problems than Touch ID :rolleyes:

    a] a mod should close this thread because this topic has been talked about to death in 35 other threads

    b] are you serious? so now i have to look straight into my phone every time i wanna unlock? that wont add more time or anything...

    c] if you're worried about someone using your finger at night, then you have bigger worries my friend. like how the freak did somebody get into your house? does that not concern you? and if it somebody who you live with, you need to set some boundaries.

    There was a crazy thread like this before.

    Basically, if you can't trust your significant other enough that she would use your fingerprints to go through your phone... then you my friend have bigger things to worry about.

    This is brought up way too often for more people not to call it out as absolutely ridiculous.

    Here are some plausible scenarios, please share if you fear this happening to you:

    1. Someone breaks into your house and creeps into your bedroom and scans your finger to open your phone?
    2. Your son/daughter wants to buy an app and you're on the couch and they sneak over and scan your finger while you sleep?
    3. You fall asleep in a tense business meeting with a competitor and they quietly scan your finger and get all your corporate secrets.
    Anyone else got some 'plausible' situations?

    My wife knows my passcode, she will be given a fingerprint on my new S. Seriously, if your partner is the type where you wouldn't give her access to your phone you have some more serious problems.

    the real flaw is how you can bypass the passcode to access your pics, emails and facebook/twitter account!!!!!!!!!!!!!!!!!!!!!!

    Seriously. If that's a major concern, quit drinking heavily and passing out in random places. :D

    Why are so many people concerned about this? Who would want access to your phone badly enough to try and use your fingerprint while you are sleeping? You people must live with some shady characters.

    Just turn off control center from your lock screen.

    I wouldn't doubt my ex gf doing something like this to me. Meh, I guess we're not longer together for a reason after 4 years together.

    It's your choice to use the feature and which finger you pick. Or use something else. Apparently a guy was able to use his penis.

    At least then you could have a good time when your crazy wife tries to look through your phone at night! :D

    Don't you have better things to spend your time doing, than to judge other people? I'm glad for anyone that doesn't have to worry about this.


    I did not post this in search of relationship advice. You're not my friend. You're a suppressive individual who is just here to ridicule my post and give reasons why my ideas are "bad". However, if so many people share my concern that there are many posts on the topic, doesn't that tend to show that my concern is valid?

    A fingerprint scanner offers a different type of security than a passcode. You don't have to be conscious or aware for the fingerprint scanner to be used. In the 90's, people would get shot for their sneakers. I'm just curious about the implications, and interested in ways of enhancing security. Why don't you either post good, constructive ideas, or just go away?

    You realize that having TouchID will make paranoid people buy this thing right? Then they will realize these various issues and post it here. Then you'll say, "You're just being paranoid." Well, duh! It's still an issue though.

    Whether or not someone's paranoia is justified is not something that can be effectively determined over this forum. I could make up whatever I want to tell you. The reality is we live in a society where a lot of crime and identity theft occurs. A lot of people are in bad relationships.

    Look at the divorce rates. If over 10% of people get divorced, that is quite a lot of people are out there currently sleeping with someone they might not want getting into their phone and e-mail records without their knowledge.

    If Apple sells 1 million phones, that's over 100,000 people who might have this concern, wouldn't you say?

    No, I had another thought. In college there were many pranks done on folks while sleeping. Being able to get into their FaceBook while they were asleep would have enabled a whole new category of super epic pranks. just saying

    Simple solution for anyone who wants to avoid their phone being accessed via TouchID while asleep...

    Turn off TouchID and don't use that functionality.

    Up until two days ago everyone in the world with an iPhone got along just swimmingly without TouchID. I suspect that they could survive just fine without it in the future.

    I do stand by my prior statement; there are many worse things that can happen to you if you sleep in the presence of someone with ill intent.

    EDIT: remember that face-unlock is easily hackable, as is even the blink-check version:

    Reboot your phone before you for you go to sleep. It will ask for the passcode after ever reboot. Seriously if I had a family member or partner do that to me and I caught them there would be a serious ass whooping.

    Lol, are you a Scientologist? That would explain a lot.

    No, I'm just using a term Scientologists use. I learned it, in fact, when I was part of a massive protest against Scientology that occurred a few years back.


    In my house that's what we call a "workaround."


    Why is it a big problem for you, if someone has an idea for how to *improve* TouchID? Hmm?

    Why are you opposed to TouchID being improved by adding additional layers of security? I don't understand that. Why wouldn't you want things to get better? For new features to continue to be added?

    People like you, who shoot down good ideas, are the reason most companies aren't Apple. It's a good idea to add layers of extra security to any security system. Sure, make them optional. Don't hassle people. But make them available just in case.
