Use a passcode with data protection
For better security, you can set a passcode that must be entered each time you turn on or wake
up iPhone.
Set a passcode. Go to Settings > Touch ID & Passcode (iPhone models with Touch ID) or
Settings > Passcode (other models), then set a 4-digit passcode.
Setting a passcode turns on data protection, using your passcode as a key to encrypt Mail
messages and attachments stored on iPhone, using 256-bit AES encryption. (Other apps may
also use data protection.)
Increase security. Turn o Simple Passcode and use a longer passcode. To enter a passcode that’s
a combination of numbers and letters, you use the keyboard. If you prefer to unlock iPhone using
the numeric keypad, create a passcode using numbers only.

Settings > Touch ID & Passcode. See Touch ID sensor, below.
