    Just wondering if anyone else has had their fingerprint stop working? Today my MacBook Pro touchID stopped working and asked me for a password after it went to sleep, after a few times of this I went into touchID in the properties, and no fingers are configured...I've had the Mac since day one, and had setup one finger, with no problems using touchID till this point...I have not gone in and removed it, and there is nobody else with access to my machine.

    Yep. I came home from work last week and opened up the lid of my MBP only to find a kernel panic. Once it finished booting, I found that my fingerprint was deleted. It's only happened once but I've only had the MBP for 3 weeks.

    My MBP is currently with Apple being "repaired" for a plethora of reasons.

    Had the same problem once, stuck on a black screen after system standby, rebooted the machine and my learned print was gone

    I also have this happening several times now. It just happened now actually. I had to put in my fingerprint again.
    It usually happens when my MBP restarts for whatever happens actually quite often that it just restarts by itself. And sometimes it seems the fingerprint gets lost...very annoying.

    Me too. I hope Apple fix this it is very time consuming to re-enter them and defeats the point of the only really useful thing about the touch bar (which I still hate as I regularly trigger things by accident)

    Aha. Same thing happened today on my 2017 MBP TB 13".

    Been using touchID since day one and this is the first time this happened in five months. I believe there is a reason though.

    My 2 cents: I was trying out a pirated software yesterday. Usually the releases of TNT comes with a Gatekeeper friendly app and it extracts the contents onto the desktop but never requires password; just a simple enter to the 'Yes' does the job. I installed CalcBot yesterday and during the gatekeeper terminal dialogue it asked for password. I've never seen this before. So maybe something happened there? Apple removes fingerprints as a measure of security vulnerabilities, I've read in placed.

    I ran Malwarebytes, KnockKnock and RansomWhere?. Where the last 2 didn't find anything, Malwarebytes found a property List item (*.plist) and quarantined it.

    EDIT: Removed both the pirated app and the quarantined file from my system.

    Might I suggest not stealing software?? And not posting about it online?? Might save you a lot of trouble...with your fingerprint being deleted, as well as other things...

    That's a weird safety feature.
    Your laptop gets stolen and all people have to do is reboot????

    You know that feeling... like you've never done something illicit willingly and then just for once you do break that, hoping that you don't get a backlash for that. I was hoping that this old thread might just avoid the eyes of such people.

    It has nothing to do with pirated software. I have lost a Touch ID as well, and all of my software is either free, or paid for.
