Works for BigONE whether or not it has its own passcode. No download needed.
Touch and hold BigONE's icon, tap Require Face ID, then confirm. On iOS 18 and later that puts BigONE 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 BigONE with Face ID
- Find BigONE 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. BigONE now asks for authentication every time it opens.
To test it, close BigONE from the App Switcher and open it again. You should see the Face ID prompt before any content appears.
Hide BigONE in App Library
- Touch and hold BigONE'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 BigONE?
BigONE is a digital wallet, the kind of app that tends to hold personal information you would not want on screen if someone borrows your unlocked phone. Wallet apps hold payment details, passes or crypto keys. Financial data on the label is expected; tracking alongside it is the thing to compare.
Finance apps need identity and financial data to function. Expect Contact Info and Financial Info; compare apps on tracking and third-party advertising instead.
A lock answers one question — who can open the app on this iPhone. It does not change what BigONE sends to its developer; for that, see BigONE's full privacy report.
