Identify what the lock protects
Apple’s Locked Private Browsing adds a local unlock step for private Safari windows. It can help keep an open private window from casual viewing when you step away. It is different from signing out of the website or hiding activity from a network provider. Decide whether the device and account are appropriate for the session first.
Check supported software
Apple documents availability beginning with Safari 17 on supported macOS releases, alongside equivalent mobile features. Inspect the current Safari settings rather than assuming every old private window can lock. The Mac can use its password or supported Touch ID for the unlock method.
Review the preference
In Safari settings, Privacy, inspect the requirement to use Touch ID or a password to view locked private tabs. Apple also documents Window, Lock All Private Windows for a manual action. Configure the preferred state and practise reopening a harmless private page before relying on it during a shared-computer session.
Observe the media exception
Apple’s support article says private windows do not lock while audio or video is playing. Do not walk away from active playback assuming an inactivity rule has hidden it. Pause or finish the session and use the documented lock action as appropriate, then inspect the actual locked state.
Finish the service session separately
When viewing is done, stop playback and use the website’s legitimate sign-out control if needed. A local private-window lock retains an open browser context; it is not account cancellation or a replacement for device security. Describe whether the window was private, locked and playing media if asking why its behaviour differed from expectation.
