Works for AuthX Authenticator whether or not it has its own passcode. No download needed.
Touch and hold AuthX Authenticator's icon, tap Require Face ID, then confirm. On iOS 18 and later that puts AuthX 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 AuthX Authenticator with Face ID
- Find AuthX 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. AuthX Authenticator now asks for authentication every time it opens.
To test it, close AuthX Authenticator from the App Switcher and open it again. You should see the Face ID prompt before any content appears.
Hide AuthX Authenticator in App Library
- Touch and hold AuthX 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 AuthX Authenticator?
AuthX 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.
Business apps often handle other people's data — clients, colleagues and customers — so what they collect can affect more than you.
A lock answers one question — who can open the app on this iPhone. It does not change what AuthX Authenticator sends to its developer; for that, see AuthX Authenticator's full privacy report.
