Since Touch ID debuted there have been numerous reports of it not working so well for some people. From high failure rates to fingerprints becoming less sensitive over time, there's no denying some people experience problems. Steve Gibson over on TWiT's Security Now podcast recently talked about how to overtrain Touch ID to get better accurate rates. Here's how to try it:
How to overtrain Touch ID for a better accuracy rate
- Launch the Settings app and tap on General.
- Tap on Touch ID & Passcode and enter your numerical passcode when prompted.
- Now tap on Touch ID.
- Here you see a list of all your registered fingerprints. Place one of your registered fingers on the Touch ID sensor. The registered print will pulse grey. Continue placing and lifting each registered finger as many times as you'd like to train Touch ID further.
Supposedly this method overtrains Touch ID further than what the initial registration does which results in better accuracy. I personally have never had issues with Touch ID but I've had friends who have and I've recommended this to them. Some are claiming it has worked but the key is to move your finger in very small increments at a time so each registered print has the best overall image of your print. If you want to hear Steve Gibson's entire explanation of overtraining Touch ID, be sure to check out the podcast in its entirety via the link below.
If you've been having issues with Touch ID accuracy, give this a try and let us know in the comments how it works for you. Did it make it any better or are you still getting high failure rates?
