Set a simple or complex passcode on your iPod Touch and it’ll prompt you for a required sign-in every time you turn on or wake the device. A simple passcode is four digits, which is enough security for some, but if you want stronger data protection, opt for a complex passcode. Complex codes are alphanumeric so you can set a long code for maximum security. Choose a passcode you’ll remember, as the iPod Touch will be disabled after six incorrect tries. If that happens, you’ll need to reset the device using an app or iTunes.Simple Passcode
Tap the “Settings” icon on your home screen.
Select “General,” and then tap “Passcode Lock” to open the passcode lock settings.
Touch “Turn Passcode On,” and then enter a four-digit passcode. Enter it a second time when prompted.Complex Passcode
Touch the “Settings” icon, and then choose “General.
Tap “Passcode Lock,” and then enter your existing simple passcode if you’ve set one up previously. If you’ve never set a passcode before, you won’t be prompted to enter one.
Slide the “Simple Passcode” slider to “Off” to be prompted to enter your old four-digit code if you’d established one before. Enter the old password a second time, if applicable.
Type in a new alphanumeric passcode when the type screen appears. Choose any combination of letters, numbers or symbols, and then tap “Next.”
Retype the complex passcode, and then tap “Done.
For maximum security, scroll to the bottom of the Passcode Lock screen and slide the “Erase Data” slider to “On.” After 10 failed sign-in attempts, the data on your iPod will be permanently erased.Warnings
If you forget your passcode and the iPod is disabled, reset the device through iTunes or the Find My Phone app. This wipes your data and reinstalls the most recent backup file.
