How to use Locked Private Browsing in Safari
Lock your private windows, so that you can keep them open and private even when you step away from your device.
Browse privately in Safari on your Apple device
When you use Private Browsing, Safari doesn't remember the pages that you visit, your search history, or your AutoFill information. Private Browsing also protects you from tracking by blocking known trackers from loading and by removing tracking used to identify individual users from URLs as you browse.
For additional privacy, your private windows can lock when you're not using them.
When your device is locked or asleep, or if you aren't actively using Safari, your private windows in Safari will lock.
When you unlock or wake up your device, or start using Safari again, just unlock your private window with Touch ID, Face ID, or your device passcode or password.
Locked Private Browsing is available starting in iOS 17, iPadOS 17, and in Safari 17 on macOS Monterey, macOS Ventura, and macOS Sonoma. If you don't find the option to lock private windows, update your device to the latest software version.
