No. As long as you have your email, Recovery File and 3D FaceLock, you will always be able to recover your account; You can also recover your account by moving from iPhone to Android by using Google Drive with your Zengo Recovery Kit. However if someone gets physical access to your phone with Zengo on it and that same person has access to your device passcode, your Zengo account is at risk as well as all other apps on your phone. It is therefore important you choose a strong device security PIN that is very hard to find to protect the access to your device. For added security, Zengo won’t even let you receive assets until your phone’s device lock is activated.
