For better security, set a passcode that needs to be entered to unlock iPad when you turn it on or wake it. Setting a passcode also turns on data protection, which encrypts your iPad data with 256-bit AES encryption. (Some apps may opt out of using data protection.)
Go to Settings
Set iPad to erase all information, media, and personal settings after 10 consecutive failed passcode attempts.
