| Description | ||||
| The macOS system's ability to automatically synchronize a user's passwords to their iCloud account must be disabled. Apple's iCloud service does not provide an organization with enough control over the storage and access of data and, therefore, password management and synchronization must be controlled by an organization-approved service. | ||||
