How to Enable a Passcode for iPhone / iPad
Virtually all iPhone and iPad users should set an iOS passcode for their individual devices. This forces anyone attempting to use the device to enter a password before being able to unlock it or gain access to anything on the device, and it also requires the same passcode before any user is able to make adjustments to certain system preferences. Setting a device access code is very simple, and unless an iOS device never leaves home, work, or school, or doesn’t have any personal data on it, it should be considered an easy yet essential security tip for all users to safeguard their devices and data.
