Before you do anything on your iPhone or iPad, you should lock it down. This is how you do it.
Data on your iPhone or iPad is encrypted with a passcode.
Go to Settings > Touch ID & Passcode, and enter your existing passcode if you have one. If not, select Turn Passcode On, and then select Passcode Options. This gives you the option of a custom alphanumeric or numeric code, or the older four-digit numeric code.
