If you've been noticing that you want to enter your passcode to release your telephone more often, as an alternative of being allowed to take action with Touch ID, you're now not on my own. With iOS 9, Apple it sounds as if made a security exchange that it is only just lately documented, which would possibly require you to enter your passcode more often ahead of you can use Contact ID once more.
The trade first popped up in Apple's May 2016 iOS Security Guide:
The passcode has now not been used to unencumber the tool within the final six days and Contact ID has now not unlocked the tool within the final 8 hours.
As famous through MacWorld, whilst folks appear to have been encountering this security function more steadily in the previous couple of weeks, Apple says that it used to be added ultimate fall with the release of iOS 9. What Apple has now not made transparent is a explanation why for the trade.
