Lockdown Mode is an extreme protection feature for iPhone. Its protections include safer wireless connectivity defaults, media handling, media sharing defaults, sandboxing, and network security optimizations.
Lockdown Mode is optional and should be used only if you believe you might be targeted by a highly sophisticated cyberattack, such as by a private company developing state-sponsored mercenary spyware. When iPhone is in Lockdown Mode, apps, websites, and features are strictly limited for security.
Here’s how to harden your iPhone from a cyberattack with Lockdown Mode.
Important: Most people are never targeted by attacks of this nature.
When iPhone is in Lockdown Mode, it doesn’t function as it typically does. Apps, websites, and features are strictly limited for security, and some functionality isn’t available, including:
- SharePlay
- Shared Albums
- FaceTime Live Photos
- FaceTime Continuity Handoff
In addition, your iPhone must be unlocked to connect with wired accessories. (Some connections are permitted for a short time after going into Lockdown Mode.)
Turn on Lockdown Mode
Go to Settings > Privacy & Security > Lockdown Mode, then tap Turn On Lockdown Mode.
If you’ve set up an Apple Watch with your iPhone, the paired Apple Watch also gets Lockdown Mode when you turn it on. This requires watchOS 10 or later.
Important: For complete protection, all of your devices must have Lockdown Mode turned on.
