Works for Colored Note whether or not it has its own passcode. No download needed.
Touch and hold Colored Note's icon, tap Require Face ID, then confirm. On iOS 18 and later that puts Colored Note behind Face ID, Touch ID or your passcode; choose Hide and Require Face ID instead to move it into App Library's Hidden folder as well.
Lock Colored Note with Face ID
- Find Colored Note on your Home Screen or in App Library.
- Touch and hold the icon until the quick-actions menu opens.
- Tap Require Face ID (or Require Touch ID / Require Passcode, depending on your iPhone).
- Tap Require Face ID again to confirm. Colored Note now asks for authentication every time it opens.
To test it, close Colored Note from the App Switcher and open it again. You should see the Face ID prompt before any content appears.
Hide Colored Note in App Library
- Touch and hold Colored Note's icon and tap Require Face ID.
- Choose Hide and Require Face ID instead of Require Face ID.
- Confirm. The icon leaves your Home Screen and moves to the Hidden folder at the bottom of App Library.
- To open it later, swipe to App Library, tap Hidden and authenticate.
Hiding also locks the app. To undo either, touch and hold the icon again and choose Don't Require Face ID.
Why lock Colored Note?
Colored Note is a encrypted notes app, the kind of app that tends to hold personal information you would not want on screen if someone borrows your unlocked phone. Notes apps quietly collect some of your most personal writing. 'Encrypted' can mean encrypted in transit, at rest on the server, or end-to-end — only the last keeps the developer out.
Lifestyle apps cover family, home and personal organisation, and often combine location, contacts and photos in one place.
A lock answers one question — who can open the app on this iPhone. It does not change what Colored Note sends to its developer; for that, see Colored Note's full privacy report.
