Apple has quietly added a new scenario for when you’ll need to enter a passcode instead of Touch ID.
Passcodes in the morning
You'll probably need to do this more often.
First noticed by MacWorld, the addition was recently highlighted in the iOS Security Guide.
Here’s the exact wording from Apple:
The passcode has not been used to unlock the device in the last six days and Touch ID has not unlocked the device in the last eight hours.
And if you’re interested, here are the other five instances where you’ll be required to enter a passcode:
• The device has just been turned on or restarted.
• The device has not been unlocked for more than 48 hours.
• The device has received a remote lock command.
• After five unsuccessful attempts to match a fingerprint.
• When setting up or enrolling new fingers with Touch ID.
Macworld found out about the change after trying to answer a reader’s question.
Apple said that the change was added with iOS 9 back in September. The company offered no precise reason for the new rule.
