When soft authentication is enabled, carers are required to enter their device passcode after a configurable period of time. This is a measure to prevent unauthorised parties from being able to access the app if the phone is found unlocked.
The app can be unlocked either by using the fingerprint sensor on the device, or the passcode they use to unlock the phone.
Soft Authentication is available in the Android app from version 5.2.0, and iOS version 0.1.8.
