Disable FaceID on iPhone if FaceID has been updated/changed
All my other security/banking apps require logging in with the account login/password if FaceID has changed. These apps do this by disabling FaceID in the apps settings when the FaceID has been changed. Proton allows a new FaceID to access the account without any other verification.
This change will prevent someone who has stolen an iPhone passcode along with the iPhone from accessing the user's Proton account.
