Apple Expands iPhone Privacy With Face ID App Locks and Passkeys in iOS 18

Q: With iOS 27's privacy-focused AI coming this fall, will manual app locking soon become obsolete?

No. iOS 27’s privacy-focused AI is unlikely to make manual app locking obsolete, because it addresses a different problem. The app-locking and app-hiding tools Apple added in iOS 18 are direct access controls. They stop another person from opening selected apps on a device without Face ID or a passcode, and they can also remove some apps from the Home Screen and suppress their notifications. That is a practical defense against shoulder-surfing, family sharing mishaps, accidental purchases, or someone briefly handling your phone. By contrast, Apple’s privacy push in iOS 27 appears centered on how AI handles data: more on-device processing, tighter controls around Siri and Apple Intelligence, and broader privacy architecture designed to limit what leaves the device or is retained in the cloud. Those measures help reduce data exposure during AI use, but they do not replace the need for a lock on a banking app, messages, or social media if someone has the phone in hand. The searched material also points to new parental controls and Screen Time updates in iOS 27, which may improve automated protections and family management. But that is still different from per-app authentication chosen by the user. The more likely outcome is that AI will complement manual locking, not replace it. Apple may eventually add smarter recommendations or automation around sensitive apps, but explicit Face ID or passcode gates remain the clearest tool for preventing unauthorized human access.

iOS 18 lets iPhone users lock individual apps with Face ID, Touch ID or a passcode, while also hiding their contents from notifications, Spotlight search and system suggestions.
Hidden apps add a second layer by removing icons from the Home Screen and placing them in a biometrically protected App Library folder for more discreet access.
Safari extends the privacy push by blocking third-party cookies, hiding IP addresses from known trackers and locking inactive Private Browsing sessions.
Apple’s Passwords app and passkeys round out the system by storing credentials in end-to-end encrypted iCloud Keychain and replacing passwords with on-device biometric sign-ins.
The broader framework also includes App Tracking Transparency, Safety Check and on-device processing, underscoring Apple’s push to make privacy controls built-in rather than optional.
