Digital Red Book: Require an Passcode on iPad

Are you afraid that the contents of your iPad might fall into the wrong hands if it's stolen or lost? You're not alone. As a simple security measure, you change the default passcode that must be entered in order to unlock the iPad.

• Go to Settings > Passcode.

• Open the Passcode section, and tap Change Passcode at the top of the page.

• Type in the current four-digit code.

• You will need to enter the new four-digit passcode you want to use.

• Type it in again, and you're set.
