To protect backups of your iPhone, iPad or iPod touch on your computer, you can use password protection and encryption.
The Encrypt local backup option in the Finder, the Apple Devices app, or iTunes locks and encodes your information. Encrypted backups can include information that unencrypted backups don't:
Your saved passwords
Wi-Fi settings
Website history
Health data
Call history
Encrypted backups don't include Face ID, Touch ID or device passcode data.
Your backup isn't encrypted by default. To encrypt a backup in the Finder, the Apple Devices app or iTunes for the first time, turn on the password-protected Encrypt local backup option. The system encrypts backups for your device from then on. You can also make a backup in iCloud, which encrypts your information.
