Device lock screen

The device lock screen is a mobile device feature. Once configured in the system settings, the user has to enter their credentials to unlock and use the device. The type of credentials depends on the operating system of the device. The following table shows the supported credentials and lock screen types.

PlatformCredential / Lock screen type
AndroidPattern, PIN or Password
iOSPasscode

The Nevis Mobile Authentication SDK requires a device lock screen to be set. Secure storage of data is only possible with an active device lock screen. The user can also combine the screen lock with a biometric credential. In this case, the screen lock can be dismissed with the chosen credential, or the biometric credential. The following table shows the supported biometric credentials.

PlatformCredential / Lock screen typeBiometric credential
AndroidPattern, PIN or PasswordFingerprint, Face Authentication
iOSPasscodeTouch ID or Face ID

The SDK still works correctly if the device lock screen is configured to use only a supported credential without a biometric credential.

info

If the device lock screen is disabled and re-enabled, the mobile application must go through all the registration processes again, since all the key materials of the secure storage are deleted. The key materials are deleted by the system because secure storage of data is only possible with an active device lock screen.
