Yu can't, you don't have that option.
When speaking about iPod Touches, 'passcode' and 'password' are two synonyms for the same meaning. 'Passcode' is used more often, though.
you need to know the actual passcode... settings/general/passcode lock
you can change the apple id password but the ipod's passcode no!
Go to Settings - General - Passcode Lock.
settings-general-passcode-set your passcode(it can be a 4-number passcode or a letter one--to get a letter one, turn off the simple passcode)
if you can remember your password, type it in, and go to settings. Go into general, then passcode lock, then, if you want to get rid of your password and wish to have passcode lock of, then press the "Turn Passcode Off" button. You will have to type in your current password though. if you wish to change your passcode, then simply press the "Change Password" button, and type your desired passcode! that's it!
go to settings then general then passcode lock
Settings>General>Passcode Lock
Settings>General>Passcode Lock Hope I Helped! (:
A PassCode can be set in the General section of the Settings on the Home Screen.
If you mean passcode (safety lock, asks for code on wake up):go to Settings on the Home Screen> General> Passcode Lock> (enter your passcode)> Turn Passcode Off> (enter your passcode again)
1) Tap the settings app. 2) General 3) Passcode Lock 4) Turn on "Simple Passcode"
