About Lockdown Mode
Lockdown Mode helps protect devices against extremely rare and highly sophisticated cyber attacks.
What is Lockdown Mode?
Lockdown Mode is an optional, extreme protection that’s designed for the very few individuals who, because of who they are or what they do, may be personally targeted by some of the most sophisticated digital threats. Most people will never be targeted by attacks of this nature.
When Lockdown Mode is enabled, your device won’t function like it usually would. To reduce the attack surface that potentially could be exploited by highly targeted mercenary spyware, certain apps, websites and features are strictly limited for security and some experiences may not be available at all.
Lockdown Mode is available in iOS 16 or later, iPadOS 16 or later, watchOS 10 or later, and macOS Ventura or later. Additional protections are available in iOS 17, iPadOS 17, watchOS 10 and macOS Sonoma. For a complete set of protections, update your devices to the latest software before turning on Lockdown Mode.
How Lockdown Mode protects your device
When Lockdown Mode is enabled, some apps and features will function differently, including:
Messages — Most message attachment types will be blocked, other than certain images, video and audio. Some features, such as links and link previews, will be unavailable.
Web browsing — Certain complex web technologies will be blocked, which may cause some websites to load more slowly or to not operate correctly. In addition, web fonts may not be displayed, and images may be replaced with a missing image icon.
FaceTime — Incoming FaceTime calls will be blocked unless you’ve previously called that person or contact. Features such as SharePlay and Live Photos are unavailable.
Apple services — Incoming invitations for Apple services, such as invitations to manage a home in the Home app, are blocked unless you have previously invited that person. Game Center is also disabled.
Photos — When you share photos, location information is excluded. Shared albums are removed from the Photos app and new Shared Album invitations are blocked. You can still view these shared albums on other devices that haven’t enabled Lockdown Mode.
Device connections — To connect your iPhone or iPad to an accessory or another computer, the device needs to be unlocked. To connect your Mac laptop with Apple silicon to an accessory, your Mac needs to be unlocked and you need to provide explicit approval.
Wireless connectivity — Your device won't automatically join non-secure Wi-Fi networks and will disconnect from a non-secure Wi-Fi network when you turn on Lockdown Mode. 2G cellular support is turned off.
Configuration profiles — Configuration profiles can’t be installed, and the device can’t be enrolled in Mobile Device Management or device supervision while in Lockdown Mode.
Phone calls and plain text messages will continue to work while Lockdown Mode is enabled. Emergency features, such as SOS emergency calls, will not be affected.

Configuration profiles and managed devices
If a device is in Lockdown Mode, new configuration profiles can‘t be installed, and the device can‘t be enrolled in Mobile Device Management or device supervision. If a user wants to install a configuration profile or management profile, they’ll need to turn off Lockdown Mode, install the profile and then re-enable Lockdown Mode, if necessary. These restrictions can prevent attackers from attempting to install malicious profiles.
A device that was already enrolled in Mobile Device Management before Lockdown Mode was enabled will remain managed. System administrators can install and remove configuration profiles on that device.
Lockdown Mode is not a configurable option for Mobile Device Management by system administrators, as it’s designed for the very small number of individual users who may be targeted by extreme cyber attacks.
