The probability that a random person could unlock the device with Touch ID is 1 in 50,000 (better than a four digit PIN but not as good as a six digit PIN).


Configure Set Auto-Lock - reduce the period for unauthorised access…

• Settings

• Auto-Lock
• Select an auto-lock time of 2 minutes or less (select ’30 seconds’ for example)

Setting a shorter auto-lock time has two benefits, it saves battery life and reduces the time anybody can access the device.

• Settings
• iCloud
• Turn Find My iPhone (or iPad) On
• Select OK

Turning Find My iPhone (or iPad) on enables the ability to track, send messages to and remote wipe a lost device.
