Does Lockdown Mode protect your photos?
Lockdown Mode hardens an iPhone against rare spyware attacks and limits photo sharing. It does nothing about a person who has your passcode.
It protects against a specific threat: highly sophisticated attacks, such as mercenary spyware. In Photos, it removes location when you share, and it removes Shared Albums. It does not lock your library or Hidden collection behind anything new, and Apple says most people are never targeted.
What changes for photos
Apple’s page says that in Lockdown Mode, location information is excluded when you share photos. Shared Albums are removed from the Photos app, and new invitations are blocked.
Your library still opens with your phone’s usual unlock. Lockdown Mode has nothing to do with who is holding the phone.
Who it is for
Think journalists, activists and officials targeted by state-backed spyware. If that may be you, also look for specialist help, since a setting cannot replace that. Protecting a source has more.
How to turn it on
Go to Settings, Privacy & Security, Lockdown Mode and tap Turn On Lockdown Mode. Apple says that for complete protection, all your devices must have it on.
Frequently asked questions
Should I turn it on just in case?
Apple says to use it only if you believe you might be targeted. It restricts apps, websites and features, so everyday use gets worse.
What about wired accessories?
Your iPhone must be unlocked to connect with wired accessories in Lockdown Mode, with a short exception right after you turn it on.
