Anyone find it odd that you can't use only the fingerprint scanner to unlock?

    I find it odd that I have to enable a passcode then set either a 4 digit or other typed passcode to use the fingerprint scanner. Doesn't that defeat the whole purpose of the fingerprint scanner because you cant use it as a standalone?

    I thought you can use it as a standalone entry system?

    I think they have you set a passcode, because after a few scans, if it doesn't read your finger, it gives you the option to put a code in. Just so there is no way that the owner can get locked out.

    But you can use the fingerprint as a unlock, without passcode.

    Try having only prints and either cutting your finger or scratching the reader. This is even a problem with the door-type readers.

    Not only scratching the reader, but what if you cut your finger thus more or less changing your fingerprint?

    It is just a back-up to your fingerprint.

    EDIT - I pretty much replied with the same thing blhoward2 said. I should read better next time...

    touch-id is just a faster way to unlock a passcode enabled iOS device; they don't touted it as a replacement for a passcode, but something to make you want to put a passcode on your iPhone since more than half the people don't use a passcode on their iPhone.

    As someone who has clipped a fingertip with some scissors, the passcode being there is great to have...

    In my case, it will be handy to have the passcode as a backup. I'm an EMS provider and I frequently use the phone (call the hospital, looking up drug dosages, protocols, etc) while I have gloves on. The touch screen works through our thin nitrile gloves, but obviously the fingerprint scanner would not work with gloves.

    The passcode is required after 48 hours without unlocking and the first time after boot. It's an extra security measure.

    I don't know how you could consider it "defeating the purpose".

    Also as far as security is concerned, you can set a long passcode thereby greatly improving security over a 4-digit PIN and then use your fingerprints primarily.

    Ok, but then it should be optional -- more like a back-up if fingerprint doesnt work.

    Agree with everyone mentioning the necessity of a passcode as backup to Touch ID.

    I'm more surprised there is no option to require both Touch ID and a passcode.

    It is optional, you don't have to use it every day. A backup only works if its established before the bad event.

    If you are in a single car crash in a remote area and you finger tip are cut from broken glasses, the 4 digit unlock code will come in handy.

    That would still run into the same problems of what happens if the Touch ID sensor goes bad or an injury to your finger changes the print. If you needed both then it would be impossible to get into your phone.

    A friend of mine was born with no fingerprints. Seriously. So if you *required* it, you're essentially telling him he cannot use an iPhone.

    No, as it has been pointed out already it is not odd at all. If your fingerprint gets damaged you might want to have another way to get into your phone, like a passcode :) Or would you better be locked out of your phone? Your topic name is misleading. Once you have set up the passcode and fingerprint scan you can just go ahead and only use the fingerprint to unlock.

    Of course a requirement would be a bad idea. I meant a user option to require both to unlock the phone. (still a bad idea, see below)

    ----------

    Ha! Good point I should have deduced that one myself.

    a] the phone needs some kind of fallback option.

    b] you have to enter your password after 2 hours of inactivity or you turn off/reset your phone.

    After two hours of inactivity or 2 days? I thought previously I had read 2 days (48 hours)...

    I slept for like 2 hours, but I don't think that really does much for me. So I think I'm in a similar boat as you, haha.

    I think you're looking at the fingerprint as being more secure than passcode, therefore it would defeat the purpose if you can still use passcode.

    This is not what touch ID is, in this case, fingerprint recognition is a way for the device to enter the passcode for you, it's a convenience.

    Now this still allows to make your phone more secure than before: in the settings, change the passcode to a complex password instead, something like frw68wde%$^jydf (as long as you remember it). That kind of strong password, you would never have entered it before because it's way too annoying to type each time you unlock. Now it takes a split second with the fingerprint.

    makes sense?

    You can use it on any part of your body that has lines. I used the lower left corner of my left hand (the place you rest your wrist on) it took a few tries but it worked.

    A guy on YouTube used a cat's paw and it worked.
