Lock Your Private Browsing Behind Face ID or Touch ID
This other privacy feature on your iPhone lets you block all your private tabs in Safari. That way, if you open an app in incognito mode, but decide to exit the app, your iPhone will immediately lock all your private tabs behind Face ID or Touch ID.
To use this feature, you need to follow these steps:
- Open the Settings app.
- Scroll down to the bottom and tap on Apps.
- Scroll down and go to Safari.
- Scroll down again and toggle on Require Face ID to Unlock Private Browsing (or “Require Touch ID” if you’re using an iPhone SE).
Like locked and hidden apps, this will fall back to asking for your passcode if biometric authentication fails. However, unlike that other feature, this fallback is still active even if Stolen Device Protection is enabled.
