Passcodes protect your iPad from unauthorized use and should be changed frequently for maximum security. If you haven’t forgotten your current passcode but are ready to update it to a new one, you can do so in the Settings app on your iPad. By default, passcodes can be any combination of four digits. In addition to changing your passcode, you can also change passcode settings such as how long it is, what characters it can contain and how long after entering sleep mode you can wait before having to enter the passcode again.
