    Can "Touch ID" be disabled" after I submit a print? Also, which finger is recommended - thumb or index?

    I just got my 6+ and I'm trying everything out. I attempted a search, but can't find anything on the subject.

    You can turn off the feature at anytime after you turn it on. You can have up to five fingerprints registered on a single device.

    Yes you can disable it. Go to settings/Touch ID and passcode.
    As for which digits to store, I would suggest those that you actually press the home button with on a regular basis. I have stored both index fingers and both thumbs.

    So it stores and accepts more than one fingerprint. I'm afraid to use it because "what if" it doesn't recognize my print later on, then I wouldn't be able to sign back on. You mentioned you had struggled with it.

    Does it allow both PASS CODE and TOUCH ID for added security or only one?

    OK Thanks!

    If you have a fingerprint set up, you must also have a passcode. This way is your fingers are cut off in a freak accident, you can still unlock your device.

    By default, it makes you also create a numeric or complex passcode that acts as a fail safe.

    Or if the Touch ID sensor fails:)
    You can still get in.

    Maybe in the future, Touch ID will encompass the entire screen and people will get better security with their butt crack print. No one can ever rip off your crack. :p

    Much to my surprise, I picked up my bothers iP6 only to have it unlock via my fingerprint. Rather amusing indeed.

    Are you an identical twin? Maybe, you both have the same identical fingerprints.

    No. But this is not unusual nor unique to touch ID. It's been widely reported that others have also experienced it.

    Passcode is also required after a hard reset, even if Touch ID is enabled.

    So you're saying that Touch ID is not that secured since you were able to use your fingerprint on your brother's phone? Interesting…

    There's a 1 in 50000 chance someone elses finger can unlock your phone using Touch ID.

    The default passcode has a 1 in 10000 since it's only 4 digits although you can increase this.

    See end of page 7 for Touch ID information:

    No

    I'm saying it's not unusual for fingerprint readers, not just Touch ID to accept others fingerprints. My example is but one of many. We have very expensive highly secure readers where I work.

    They are used in a wide variety of applications since we do classified work. They are used in combination with 32 character passwords to insure complete security since fingerprint readers alone are not as secure as they're advertised to be.

    Touch ID is secure enough for me. Anything is possible, I guess my 12 character phone password could be guessed as well but I'll take that chance also. Your post is the first I've heard about unauthorized fingerprints unless your fingerprint was already in the phone or identical to your brothers. At any rate I'm not worried my fingerprints are all over the map.

    At any rate, Touch ID can be disabled.
