Protect your inbox with the security of TouchID and FaceID (iOS app only), and require your finger or face to unlock the Email app. Follow these instructions to enable the feature:
- Tap the menu icon in the upper-left corner
- Tap Settings
- Tap Enable TouchID (or Face ID) and ensure Enable is turned on.
- Set your preferred amount of time before the app prompts you for your fingerprint/face to unlock again. You can choose between immediately, after 1 minute, after 5 minutes, after 15 minutes, after 30 minutes, and after an hour.
- Now you'll be required to verify your identity in order to open the app after your preferred amount of time has passed.
