Works for Email for Hotmail whether or not it has its own passcode. No download needed.
Touch and hold Email for Hotmail's icon, tap Require Face ID, then confirm. On iOS 18 and later that puts Email for Hotmail 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 Email for Hotmail with Face ID
- Find Email for Hotmail 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. Email for Hotmail now asks for authentication every time it opens.
To test it, close Email for Hotmail from the App Switcher and open it again. You should see the Face ID prompt before any content appears.
Hide Email for Hotmail in App Library
- Touch and hold Email for Hotmail'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.

Hiding also locks the app. To undo either, touch and hold the icon again and choose Don't Require Face ID.
Why lock Email for Hotmail?
Email for Hotmail is a secure email app, the kind of app that tends to hold personal information you would not want on screen if someone borrows your unlocked phone. Email apps see every message and contact. Third-party mail clients may route mail through their own servers to offer features like push or AI summaries.
Utilities range from calculators to VPNs, so their labels vary more than any other category. A simple tool that collects identifiers and usage data for tracking is a sign of advertising SDKs.
A lock answers one question — who can open the app on this iPhone. It does not change what Email for Hotmail sends to its developer; for that, see Email for Hotmail's full privacy report.
