Security

In computing, security is protection against unauthorized access to, or alteration of, information and system resources including CPUs, storage devices and software.

Usage in Apple platforms

 * iOS and iPadOS users can secure their mobile device by setting Face ID or Touch ID along with a passcode.
 * macOS users with administrator permissions can access the Security & Privacy pane of System Preferences. Passwords can be set in the Users & Groups pane.
 * An Apple ID can be used to enable Activation Lock on a supported iPhone, iPad, or Mac for further protection in case it is stolen.
