Works for Octopus Authenticator whether or not it has its own passcode. No download needed.
Touch and hold Octopus Authenticator's icon, tap Require Face ID, then confirm. On iOS 18 and later that puts Octopus Authenticator 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 Octopus Authenticator with Face ID
- Find Octopus Authenticator 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. Octopus Authenticator now asks for authentication every time it opens.
To test it, close Octopus Authenticator from the App Switcher and open it again. You should see the Face ID prompt before any content appears.
Hide Octopus Authenticator in App Library
- Touch and hold Octopus Authenticator'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 Octopus Authenticator?
Octopus Authenticator is a authenticator app, the kind of app that tends to hold personal information you would not want on screen if someone borrows your unlocked phone. Authenticator apps generate the second factor for your logins. The biggest practical risk is not data collection but losing your codes when you lose your phone.
Productivity apps tend to collect the work you do in them — documents, notes and files — so User Content is common. The question is whether it syncs to the developer's servers and how it is protected there.
A lock answers one question — who can open the app on this iPhone. It does not change what Octopus Authenticator sends to its developer; for that, see Octopus Authenticator's full privacy report.
