Enable encrypted backups in Apple Configurator
Backups are normally not encrypted. However, you may want to use encrypted backups to save users’ passwords. In this way, you make sure that no one without a password can view the backups, even if they have access to the Mac with Apple Configurator installed.
In Apple Configurator , select one or more devices or Blueprints.
Do one of the following:
Choose Actions > Advanced > Enable Encrypted Backups.
Control-click the selected devices or Blueprints, and choose Advanced > Enable Encrypted Backups.
If you selected devices, enter a password and verify it, then click Set Password.
